Roofing and Snow: Everything You Need to Know – Part One

What to consider when designing and building in snow-prone areas.

While properly-designed metal roofs historically perform well in winter, heavy snowfall can be detrimental to buildings of all kinds. Those who live and work in and around them are also at risk when snow and ice cause dangerous situations. Even though winter doesn’t formally begin until late December, colder weather is upon us. And while you might not be expecting snow or ice yet, keep these roofing and snow tips in mind when designing, constructing and maintaining structures in areas where there’s a chance for snow and/or ice over the course of the year.

Considerations for Snow-Bearing Roofs:

  1. Anticipate Snow Load

Snow accumulates on every roof type, and as this happens, it increases the amount of weight your structure is bearing. This increased weight (snow load) can pose several threats to the structure and those in and around it. For example, when the weight of snow or ponded water from melted snow exceeds the structure’s limits, the roof or even the entire structure can collapse. Be sure you’re aware of the weight your structure can bear and remove snow to keep it within its limits. Consult the International Building Code (IBC) as well as state and local codes for guidance based on your location.

  1. Prevent Ice Dams

Most ice dams are the result of air barrier flaws in buildings. If warm indoor air escapes through the roof floor, it warms the roof sheathing and melts the underside of the layer of snow on top. This water then moves down the slope of the roof toward the eaves, where it freezes into ice. As this process continues, the ice gets thicker and thicker, resulting in ice dams. The presence of these dams allow water to back up and form a reservoir that can cause major damage.

To prevent ice dams, you should:

  • Seal all air leaks at the attic floor
  • Ensure proper insulation
  • Provide adequate attic ventilation

Another tip is to use a peel and stick membrane on the roof deck extending from the eave to about 3’ up-slope from the exterior wall. For more specific details on the ice dam prevention tips above, read our recent blog post.

  1. Prevent Sliding Snow

Gravity can cause accumulated snow to slide down the roof’s slope (shedding), potentially injuring people and damaging property below. Despite this, snow shedding must occur to keep the snow load from accumulating beyond the buildings structural limits. Balancing snow load and shedding is important and requires that you consider geographical and building material and roof design factors.

Ice and snow sliding down the main roof has damaged the roof panels and the valley trim on this connector roof.

Roof slopes of 45 degrees (12:12) or more, can accelerate sliding snow with sometimes immense and dangerous consequences. For example, if snow accumulates and then falls onto an exterior gas line, pipes could rupture. From there, the smallest of ignition sources could set the structure ablaze. In addition, the weight of sliding snow can propel any icicles formed on eaves can be propelled down by the force and weight of sliding snow onto people and property below.

On slopes less than 45 degrees (6:12 to 9:12), low amounts of friction (like on smooth roof surfaces) means it offers less resistance to sliding. Striations and embossing on roofing materials like metal panels add a small 3D profile and improve the resistance to sliding, especially when they run traverse to the slope.

This can get complicated, but in general, installing metal panels with snow retention devices on a steeply-sloped roof is recommended. This approach will naturally shed snow and ice, and protect your structure from excessive snow loads. If you have a low-sloped roof, be sure it’s design supports snow as shedding won’t occur naturally. Including enough snow retention devices from ridge to eave is also imperative for this design.

  1. Use Retention Systems

A variety of retention options, such as snow fences, bars or guards, are designed to make snow and ice melt completely or fall from roofs in small amounts. This helps reduce risks associated with sudden rooftop avalanches while maintaining the clean lines of the roof. It is important that snow retention systems are carefully engineered and properly installed. Models like S-5!’s snow-retention device design resource allow you to input your roof dimensions and expected snow load to adequately engineer snow fence assemblies.

  1. Protect Roof Attachments

The weight of sliding snow can be powerful enough to take off attachments like exhaust vents. To combat this, reduce the shear load by installing rigid vent pipes securely and as high up on the roof slope as possible. If this is not possible, protect the pipes with a snow retention system.

While metal roofing responds well to harsh winter weather, it is imperative to take the time to keep snow, ice and moisture from causing issues. No matter the roofing design or material used, keeping people and property safe from overhead dangers should be a priority when designing, installing and maintain your structure.

In part two of this roofing and snow series, we’ll review additional considerations. It contains tips on roof layout, color, weathertightness and maintenance, which also play important roles in winter weather protection.

Advancements in Metal Roof and Wall Panels

The evolution of metal roof and wall panels in the steel building industry.

ABC Blog | Advancements in Metal Roof and Wall Panels

Metal roof and wall panels are commonly used in today’s building industry and are highly valued for their versatility, durability and aesthetic features. This wasn’t always the case, though. Over the last several decades, the metal building industry has evolved and the use of metal panels and coordinated metal building components is now a major boon for builders as it helps them provide on-time, on-budget, attractive project to a wide-ranging customer base.

To meet changing demands and standards, the industry has continued to develop and progress since the Industrial Revolution. This era saw more than just an increase in the use of iron as a construction material. In the late 1880s, metal became a profitable option well-suited for steel-framed buildings, skyscrapers and train stations. During WWII and in the decades that followed, modern steel became the universal standard. Common uses included military shelters, oil storage, churches and private buildings—including landmarks like the Empire State Building.

 1940s – 1950s:

During the 1940s and 1950s, industry sales centered around standardized buildings (pre-engineered)—mostly to the agricultural, industrial and government markets. Typically unpainted and unattractive, these metal roof and wall panels simply met their functional purpose. However, their ability to be ordered, delivered and installed quickly and easily made them very valuable.

1960s:

The innovation of pre-painted wall panels in 1959 transformed the metal building industry. Formerly focused on agricultural and industrial end-uses, the additional color options made metal panels more appealing to commercial markets. In the late 1960s, the innovative standing-seam metal roof panel delivered advantages previously unheard of. As seen with American Building Components’ LokSeam® panel, this design features fewer seams that are raised above the panel. With fasteners situated above the panel level, the risk of damage from moisture that can collect there is reduced. Standing seam metal roofs are also designed to allow for expansion and contraction that naturally occurs as a result of changing temperatures. This provided owners, designers and contractors with a high-quality roof that can be specified and used for large buildings. Their low upfront cost and superior performance and lifespan made metal buildings the preferred solution for low-rise, non-residential buildings.

1970s – 1980s:

In the 1970s, the metal panel industry primarily focused on commercial, industrial and agricultural buildings of 10,000 sq.ft. or smaller. In the 1980s, the industry continued to grow in response to customer and market needs. New coating technologies were introduced to provide better corrosion resistance, making metal buildings a more viable long-term option. Technological advances in wind loading for walls and wind uplift for roofs also addressed structural engineering concerns previously held.

1990s:

In the 1990s, metal building construction nearly doubled because metal had proven to be flexible, cost-efficient and time-saving. As a result. the industry expanded to include retail buildings and civil/service facilities, such as schools and hospitals. Emerging metal panel technology, such as snow load solutions, was beginning to be investigated and addressed. In particular, the advancement of computer technology helped create more robust design systems. This enabled manufacturers and contractors to quickly price and deliver detailed preliminary design drawings with greater efficiency and accuracy.

Early 2000s:

The first two decades of this century brought more diverse product and service offerings to the market. These included practical and aesthetic innovations like insulated metal panels (IMPs) as well as new roofing finishes. This decade also saw a new focus on metal building safety in response to dangerous California earthquakes. To help mitigate the risks, research into the structural implications of seismic activity was conducted, resulting in updated building standards. Customer requirements also drove energy performance optimization and engineering guidelines for tapered structural components, and new exterior finishes and styles for metal roof and wall panels were introduced. This included the use of horizontal instead of vertical siding systems and smooth-surface panel faces.

Today…and Beyond:

The dramatic and innovative industry advancements of the past have given way to the full and complete metal panel solutions for a wide range of building types—including unconventional ones like custom residences—that we enjoy today. Continued research, partnerships and collaboration are further driving industry expansion and diversification—a trend that shows no sign of slowing.

What You Need to Know About Insulated Metal Panels

Insulated Metal Panels (IMPs), simply put, are the insulated version of single-skin (uninsulated) metal panels. As the name suggests, IMPs provide insulation and, therefore, thermal control and barrier protection to structures. This helps ensure air, heat and moisture stay outside of a building, reducing the chances of mold, corrosion and rotting.

ABC Blog: Insulated Metal Panels (IMPs)A versatile and practical choice, IMPs are designed for many roof and vertical and horizontal wall applications—including ceiling panels and wall partitions for commercial, industrial and post-frame building types. IMPs are ideal for sustainability-minded designs, offering excellent R-values (indicating their insulating power) and improving energy efficiency. What’s more, they’re available in various colors, thicknesses, widths and finishes, providing many customization options to choose from.

Here, we’ll take a look at some of the many benefits of using IMPs. Plus, we’ll review some factors to consider when deciding if IMPs are the right choice for a building project.

Choosing IMPs:

There are several important factors that go into the decision to use IMPs. While they offer tremendous benefits, it’s always good to research the product to ensure it meets your needs. The manufacturer, as always, is a great resource to help determine the optimal material and product, given all the parameters. Here are some of the main factors to consider.

 Benefits of using IMPs:
  • Installation and Maintenance: IMPs have similar requirements to single-skin in terms of time and labor.
  • Longevity: IMPs can enhance the building lifespan, as they protect from unwanted and damaging heat and moisture.
  • Versatility: Available in a range of panel colors, thicknesses, widths and finishes, IMPs offer many customization options.
  • Energy Savings: Because they help regulate interior temperature, IMPs are more effective at energy conservation as compared to single-skin panels.
  • Energy Performance: Contractors and builders can use IMPs to achieve necessary energy performance levels with this single-source enclosure, providing a continuous blanket of protection.
  • R-Value Performance: IMP tests show thermal performance values up to R-8.515 (roof panels) and 7.08 (wall panels) per inch of panel thickness. i.e., a 2.5-inch-deep panel would easily meet the International Energy Conservation Code and ASHRAE minimums.
  • Cost: While generally more expensive than single-skin panels, this cost is often offset by long-term savings.
  • Tax Savings: Federal, state and/or local governments often offer incentives for using sustainable or “green” products that meet energy-efficiency requirements. Your personal tax advisor can share more information on any currently available incentive programs.
How to know if you need an insulated metal panel:
  • Building Type/End Use: Any structure that will hold people or goods should consider using IMPs. Specialized facilities that require reliable temperature and moisture regulation are excellent candidates for IMP use. These include refrigerated warehouses, research laboratories, government facilities, defense contractors, technology companies, MRI clinics and food production facilities, to name a few.
  • Geography and Weather: Depending on region/weather considerations, IMPs might be the best choice. To help determine if that is the case, you can calculate the functional amount of insulation needed in your area by using the minimum rated R-values method or the maximum U-factor assembly calculation. [For IMPs, the Maximum U-Factor Assembly calculations is recommended and can be tested using ASTM C1363.]
  • Meeting Fire Rating Requirements: To become fire-rated, IMP manufacturers can submit full-size product samples to a testing laboratory like Underwriters Laboratories (UL). The products are then tested according to standard, agreed-upon procedures such as ANSI/UL 263, “Standard for Fire Tests of Building Construction and Materials.” The manufacturer can provide confirmation as to whether a particular IMP meets the requirement for your project.

All things considered, the advantages IMPs offer often make them ideal for many building applications. This is particularly true when it comes to energy efficiency and sustainability for the post-frame, commercial, industrial and institutional markets. For more information on IMPs, check out ABC’s IMP resources or reach out to an ABC representative in your area.

Metal Panel Color Selection—What to Consider

Choosing a metal panel color can feel daunting these days. With the number of available metal building colors having expanded from the usual white, tan and Galvalume to more than a couple of dozen options, where do you begin? What factors should influence your decision? Read on for recommendations on key questions to ask to help you make the best decision for both the desired aesthetic as well as longevity, durability and energy efficiency of your metal project.

What colors are metal products available in?

This is the most obvious consideration and can be answered with a simple search of the metal product manufacturer’s website. Authorized dealers also often have physical metal panel color charts,  samples or chips from metal product manufacturers for in-person review. While metal panel color options used to be limited to standard stock colors like white, tan and Galvalume, today, many manufacturers are able to offer many more color options outright as well as additional custom colors. These new metal panel color options now include metallic paints, as well as ones with metal flecks that add sheen and sparkle, giving the panel color more depth and durability.

How can I be sure I’m getting the exact metal panel color I think I’m getting?

Upon request, most metal panel manufacturers are more than happy to provide actual color chips so you can see the exact color in person. While the chips on color charts are a close facsimile, getting color chips from the plant is ideal to ensure a perfect match. Additionally, you can view images of completed projects on the manufacturer’s website as seen in ABC’s Project Gallery. This section not only shows you photos of real-life building projects using our metal products so you can see how colors look in different combination and on different building types, but it also provides details on the products and colors used with additional resources to help you make your selection.

In addition, ABC’s Color Visualizer helps you envision your actual project before you even order your metal panels. You can upload your own photo or choose from our sample project photos to pick your ideal panel type and color. While it’s useful to review the manufacturer’s website and color visualization for project images and ideas, keep in mind that colors may look a bit different on your computer than they do in real life.

ABC Metal Panel Color Resources

How to select the right color for optimal energy efficiency?

Cool metal roofs have been shown to be among the most sustainable and energy-efficient choices out there. They are designed to reflect more of the sun’s energy (and heat) back into the atmosphere to keep your building cooler and reduce your air-conditioning bills. (Read more about cool metal roofs in our blog post.)While lighter colors are generally the best option to optimize cooling effects, it should be stated that improved energy performance is a result of much more than just the roof’s color. The Cool Roof rating of paints and coating systems used by metal panel manufacturers are generally listed with the color choices on the manufacturer’s website. For detailed information, a great resource is the Cool Roof Rating Council, which maintains a products directory that lists solar reflectivity and thermal emissivity values for many roofing brands.

ABC offers the most sophisticated silicone polyester coating paint system in the industry. It offers optimum exterior protection and superior resistance to chemical corrosion and ultraviolet radiation, and most of our paint coatings are ENERGY STAR® qualified.

Can I paint over my metal panels?

If you’re considering painting your metal panels, trim or accessories, you should first check with the metal product manufacturer to ensure you won’t be voiding any warranties. You can also ask the manufacturer about touch-up paint and the correct way to apply it if small corrections need to be made. If you do decide to completely re-paint your panels, it’s best to get the panel manufacturer’s recommendation on the best paint and application products/methods to use to ensure you don’t damage the steel underneath the paint.

What if my paint isn’t performing the way I expect it to?

Most manufacturers offer a limited warranty on their paint systems. Before you buy, be sure you understand the limits of the warranty. If you think your situation warrants a claim, take pictures of the product and send them to the manufacturer to start the process. Do not attempt to correct or cover any issues as this will likely void your warranty. The manufacturer will likely send someone out to look at your material and will keep you informed throughout the process.

Armed with the right questions, resources and, hopefully, color charts and samples, choosing a color for your new metal roof can be an exciting part of the process. Your job is to take the time to review the options to make the most practical and aesthetically appropriate decision. ABC representatives are always ready with the resources and information you need, so feel free to contact one of our team members with your questions.

Using Personal Protective Equipment (PPE) to Safely Install Metal Roofs

Anyone who has installed a metal roof knows it can be a dangerous business. With risks ranging from slips and falls to debris and even skin damage as a result of sun exposure, the installer needs to be cognizant of all safety considerations to mitigate personal injury. The good news is that wearing the proper Personal Protective Equipment (PPE) can greatly reduce the risk—and severity—of potential injuries.

Here we’ll review gear that can help ensure personal safety on jobsites and recommend equipment to always have on hand.

Standard Construction Safety Equipment

 

Safety Gear Recommendations:

Gloves—the thicker the better for optimal protection from cutting one’s hand on the sharp edges and corners of sheet metal. According to the Metal Construction Association’s (MCA’s) Metal Roof Installation Manual, clean leather gloves that allow for a good grip are the the best injury protection. (Dirty gloves can soil and scratch the panel surface.) Gloves also protect hands from burns when handling materials heated by sun exposure.

Hard Hats—according to OSHA, when exposed to the possibility of head injuries, hard hats should be worn. Roof work, especially handling metal materials, does raise the possibility. It is critical to ensure the hard hat fits properly to maximize their protective effectiveness.

Eye Wear—ensure protective eyewear features side shields to prevent metal shavings or any other airborne debris from damaging the eyes.

Fall Protection—slips and falls are, perhaps, the most obvious risk when installing metal roofs. Recommended gear includes a tie-off safety harness, non-skid footwear and mesh netted “Fall-Saver” insulation laid underneath the roof to help prevent falling through.

Toe Protection—in addition to being durable and having non-slip soles, steel-toed boots can help protect installers’ toes from injury.

Forearm Guards—Even lightly brushing against an exposed metal panel edge can result in serious injury. Forearm guards made of chainmail or Kevlar are recommended to prevent wounds.

Reflective Vests—these are a key piece of safety wear critical for alerting others to a workers’ presence. This is particularly important if there are vehicles or mobile machinery on site.

Proper Clothing—perhaps the most obvious recommendation is to wear fitted clothing. Loose clothing can get caught on sharp material and in machinery, which can cause serious, irreversible injury. Long-sleeved shirts and pants should be worn to protect skin from metal shavings and sun damage.

 

 

 

General Construction Site Safety:

In addition to the specific PPE listed above, the saying “Better safe than sorry.” can’t be overstated. The following is a checklist of common-sense equipment and other items that should always be on every construction site:

  • First-Aid Kit
  • CPR/AED kits
  • Fire extinguisher
  • Working access to /communication with Emergency services
  • ICE (In Case of Emergency) contact information for all personnel
  • Water
Additional Resources:

To learn more about PPE and safeguarding against injury when installing metals roofs, OSHA construction site safety guidelines and Metal Construction Association’s Metal Roof Installation Manual (Chapter 9: Safety Issues) are great resources. You can also learn more about metal panel installation considerations from our recent blog post. And, of course, the American Building Components team is always available to answer questions and provide guidance.

 

When to Call a Metal Panel Manufacturer: Part II

In Part 1 of this series, the success of a metal roof or wall project can rest heavily on the installer’s ability to recognize issues. When that happens, calling the manufacturer is not just suggested, but imperative to ensure any potential problem is averted before it’s too late. In addition to issues like damage to the physical panel or problems with the fasteners discussed previously, let’s take a closer look at a few other common circumstances under which ABC recommends reaching out to the manufacturer:

Alignment and Substrate Issues

The installer is responsible for verifying the condition of the substrate and checking for proper alignment before attaching any sheeting materials. If the installer notices any issues like this (either before installation or once they begin laying panels), they should stop and address them immediately. This might include oil canning or other irregularities in panel appearance. The installer should investigate the source, and—if unable to identify and properly remedy the situation on their own—they should call to the manufacturer’s support team. They may be able to suggest ways to identify source of the problem—whether it be installation or manufacturing—and from there, make suggestions on how to best address the situation.

 

Accessories

Adding penetrative accessories such as snow guards or mechanical curbs to a roof or installing doors, windows or louvers to walls can impact the system, its weather-tightness and appearance. Oftentimes, accessory installers with little or no knowledge of metal sheeting systems come onto the job to perform accessory installation. In these cases, it’s wise to visit with manufacturer prior to installation of these accessories and to alert the non-metal panel installer of precautions the manufacturer suggests be taken.

The image at left represent several installation issues that could have been avoided by calling the metal manufacturer prior to installation. The piping used is not compatible with metal roofing and was not installed in such a way to prevent issues with roof performance, including leaking and water damage.

Manufacturer recommendations can vary based on the panel type and building slope, as well as on the accessory and fastener type, and installation location.

Another factor to consider when adding accessories to your metal building is that some material types can react negatively with the installed metal system and lead to damage as well as void manufacturers warranties. Since accessories can be make of many different types of material, any potential accessories should always be researched prior to installation to ensure the material type is compatible with your metal roof and/or wall system.

 

Panel Engagement

Panel systems are designed and engineered to attach and engage one another to ensure optimal performance. These specification are outlined in the manufacturer’s installation manuals and project drawings. If at any point the panel does not engage as depicted in the details, installation should be halted and reviewed to determine the cause. This can require a call to the manufacturer to help determine if the matter is site- and/or substrate-related or if it’s a manufacturing issue requiring replacement material.

Panel engagement issues that warrant ceasing installation and making a call to the manufacturer include:

  • laps are not nesting properly
  • clips are not engaging as they should
  • panel modularity can’t be controlled
  • panels aren’t “resting” on the substrate—causing excessive bowing and stress

Once the material is completely installed, it is much more difficult to determine the cause of a problem and is potentially more expensive to remedy. Additionally, in many cases, full installation constitutes acceptance of the product and the manufacturer’s hands could be tied or extremely limited in being able to assist in remedying after the fact.

By knowing when to be proactive with a call to the manufacturer, installers can mitigate many types of potential pitfalls. And if you’re just not sure, it’s best to call.

When to Call a Metal Panel Manufacturer: Part 1

Each metal building installation is unique and even the most experienced of installers can run into trouble on a job. Whether a panel isn’t engaging properly, it’s not meeting stated tolerances or fasteners are missing or not working, anyone who takes on the task of installing metal panels needs to know when to call a metal panel manufacturer for support, guidance and resources at any time to ensure the success of their project.

ABC Blog: When to Call a Metal Panel Manufacturer

Manufacturer Resources:

While it’s not the manufacturer’s responsibility to guarantee their panels are installed correctly, reputable manufacturers should set installers up for success. They can do this by providing product resources and recommendations on how to alleviate or mitigate potential pitfalls, and by sharing tips on how to avoid common mistakes that other installers have made.

  • Product Installation Manuals and Construction Drawings: Before installation begins, the product installation manual and detailed construction drawings should be reviewed by the installer—especially if this is his or her first time working with the product. These resources contain all the product information needed as well as installation best practices. American Building Components makes product details and installation information available to metal panel dealers and distributors through shop.abcmetalroofing.com. If you’re a dealer or distributor, click here to learn more and sign up for an account!

Installation techniques can vary based on the unique dimensions of the panel as well as on the actual building design. When an issue arises that is beyond an installer’s expertise, it’s in the best interest of everyone involved to call a metal panel manufacturer for input before permanent mistakes are made.

When to Call a Metal Panel Manufacturer

Examples of when American Building Components recommends that an installer immediately call a metal panel manufacturer are:

  • Product Damage: Building owners may not always be able to recognize material damage and understand how it can be detrimental. Therefore, installers should always evaluate all building materials before any installation begins. If—after review—damage is suspected, the building owner should take pictures of the damage and notify the manufacturer immediately. The manufacturer will advise if the issue is minor and installation can begin, or if the panels should not be installed. The last thing you want to do is install damaged panels and have to uninstall them and wait for new materials. The impact of removing and replacing panels like this will significantly increase cost and delay the construction schedule.
  • Fastener Issues: The type of fastener used depends on the material they will be fastening to (substrate). If the substrate differs from what’s stated in the project details, check with the manufacturer to verify that the provided fasteners can be used. If the screws aren’t engaging properly, or there any problems with the fastener type. The manufacturer can advise how to move forward based on the project details. In short, substituting fasteners with ones not supplied by the manufacturer is never recommended.

Remember: no problem is too small to call a metal panel manufacturer for advice! In part two of this series, we’ll share more situations when calling the manufacturer will save time, money and headache.

Concealed v. Through-Fastened Metal Roof and Wall Panels: How to Choose

All metal panels—whether for commercial, residential, industrial or agricultural applications—are attached to the structure using either fasteners, clips or a combination of both that keep them in place. Vertical panels, in particular, are often categorized by the type of fastening method used to attach them, which is most often either using hidden/concealed fasteners or using an exposed (through-fastened) method. Here we’ll look at the benefits your customers can experience when using these common fastening types, as well as their differentiators, including price/budget, durability, aesthetics and ease of installation.

Concealed-Fastened Roofing Panels

Concealed-fastened panels are attached to the substrate with clips, which means the panels are not pierced to secure the connection. The clips and fasteners, therefore, are concealed underneath the metal panels when properly installed—arguably making the roof more aesthetically pleasing. These panels are offered in various styles, depending on which options your customers choose and additional job-specific considerations. This method is common in architectural and residential applications where a clean appearance and protection from environmental exposure are priorities.

Through-Fastened (Exposed) Roofing Panels

Through-fastened panels are generally attached with screws or nails, which puncture the overlapping roofing sections to lock the panels into place. They are also installed using washers, which provide leakage protection around the puncture hole. The fasteners are on the outside face of the panel and are visible even after the installation is complete.

So, how do your customers decide which option is right for their project? See below for some factors that can help them choose between a concealed- or through-fastened approach.

Key Considerations

Price/Budget:

Concealed: Typically, concealed-fastened panels can be more expensive overall due to the longer installation time required. In addition to increasing the labor cost, this installation method also takes longer, which affects your customer’s project schedule. However, ABC’s SL-16® panel can be installed faster and for about the same cost as exposed-fastened panel systems.

Through-fastened: While less expensive, through-fastened applications are more prone to issues. For example, if a washer fails, the screw can pop, which allows water in and can cause leaks and corrosion. While washer material is of a higher quality and more dependable than in the past, this is still a concern.

Durability:

Concealed: Because concealed fasteners have limited weather exposure, they therefore generally have a longer lifespan than panels with exposed fasteners. Additionally, there is less wear and tear since concealed panel fasteners are not as affected by the metal panel expansion and contraction that occurs when temperatures fluctuate as exposed-fastened panels are.

Through-fastened: Because concealed fasteners have limited weather exposure, they generally have a longer lifespan than panels with exposed fasteners. Additionally, there is less wear and tear since concealed panel fasteners are not as affected by the metal panel expansion and contraction that occurs when temperatures fluctuate as exposed-fastened panels are.

Aesthetics:

Concealed: Aesthetically, the main question is whether your customers want the screws to be visible or if it’s important that they are hidden. A concealed-fastened application is considered more aesthetically pleasing, as the lack of visible fasteners, creating a smooth, clean appearance. Generally, residential and architectural buildings favor concealed-fastened roofing panels.

Through-fastened: As stated, the hundreds of fasteners required to secure panels are exposed and visible on the outside of the panels. This method is often used on agricultural and industrial buildings, as clean aesthetics are usually less important for customers in these markets.

Ease of Installation:

Concealed: Installing concealed-fastened metal panel systems is time-consuming and complicated as compared to through-fastened. In fact, the complexity of the process dissuades many DIY installers from taking on the task.

Through-fastened: Exposed-fastened metal panel systems require less installation time as each fastener is drilled directly onto the outside of the panels. This makes it the method of choice for the majority of DIY installers. Overall, this method works well with simple structures but can be difficult to use on more complex projects. It should also be noted that through-fastened panels should be installed with care so that there is proper sealing. There also may be length limitations due to thermal movement.

Conclusion

The type of fastener system your customers choose for a given metal panel project will depend on a wide array of factors—budget, durability, aesthetics and ease of installation. Making the right choice is one step in ensuring the success and integrity of their building for years to come.

Proper Ventilation for Metal Roofs and Walls

Selecting metal roof and wall panels is a strategic investment for the life of a building. To protect their investment, it is key that your customers ensure the proper ventilation system is installed. Optimal air movement not only promotes temperature regulation and energy efficiency but also reduces the risk of moisture-related issues like condensation build-up. Here, we look at some of the main ventilation considerations and resources your customers need to ensure success.

ABC Blog: Proper Ventilation of Metal Roofs and Walls

Why is proper ventilation important?

Proper ventilation helps optimize the performance and efficiency of metal buildings by:

  1. Controlling condensation

Condensation can wreak havoc on metal, causing corrosion, reduced thermal performance of insulation, mold and mildew growth, and even insect infestations. For example, in warm and humid areas, outside air that enters a building without moving through a ventilation system can bring with it large amounts of humidity. This humid air can create an uncomfortable environment, accelerate panel weathering and increase the possibility of mold growth. This issue is worsened when the outside temperature falls below the inside temperature, creating a perfect breeding ground for condensation development.

  1. Regulating temperature

Regulating and maintaining ideal interior temperature can help cool the building in warmer months, keeping the structure comfortable to occupy. Temperature regulation also helps protect the integrity of the building from excess (and premature) metal panel expansion and contraction. This movement can weaken the integrity of fasteners, which are designed to keep panels from detaching/pulling away from the substrate.

  1. Preserving air quality inside the building

Proper ventilation helps remove volatile organic compounds and other air pollutants that are detrimental to human health and productivity. The Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) have published guidance on indoor air quality standards in commercial/institutional buildings. These standards help determine ventilation needs that need to be met to ensure compliance.

Who Needs Ventilation?

As expected, most structures require proper ventilation in accordance with their geographic location, contents and/or building end-use. Structures housing chemicals or moist substances require more ventilation than those storing dry goods in relatively arid environments. Ventilating a building that stores ceramic in the desert is very different than ventilating an indoor sauna in practically any geographic location. Agricultural facilities in particular must employ proper ventilation to mitigate the dangers posed by ammonia and other corrosive airborne fumes. (See our Animal Housing blog post for more.)

How to Ensure Proper Ventilation:

Similarly, the ideal amount and type of ventilation your customers need depends on their building’s unique specifications and end use. Generally, structures larger than 2,400 sq. ft. may require more than one type of ventilator to allow air to move between them (cross-ventilation). Structures that house people, animals and/or valuable material also benefit from cross-ventilation using ridge vents near the roof and a louver vent located closer to the structure’s floor. In these cases, it is recommended that your customers work with design professionals and building engineers who can help determine the building ventilation requirements. These professionals can recommend the appropriate, high-quality metal panels and components that suit the unique requirements of their project.

So, what ventilation options are available for your customers? Ventilation solutions fall into two main categories: natural (unpowered) and mechanical (electrically assisted):

  • Natural ventilation methods include installing a ridge and eave vents that enable air to circulate naturally through the building. Your customers can also use vents that capitalize on the natural vacuum created when air moves quickly over angled surfaces like roofs. The lower pressure in this vacuum draws air out of the building—most often through ridge vents. This choice will depend on your customer’s aesthetic preferences and/or installation location limitations.

 

  • Mechanical or power-assisted ventilation helps draw more cubic feet of air into and out of the space per minute. Powered fans with curved blades and/or louvers are often used to achieve greater air flow. As previously noted, air flow is vital in preventing condensation, so this is particularly helpful in naturally humid environments.

Conclusion

In conclusion, proper ventilation is a critical component of any high-quality building. As metal panels are becoming more popular, understanding how to achieve an effective ventilation system can help ensure the success of your customers’ building projects.
