How To Cut Metal Panels

Posted on October 21, 2020May 31, 2023 by Tyler Roose

Even with an accurate materials list, cutting metal roof and wall panels on-site is often a necessary part of the installation process. To avoid damaging your metal panels, it’s important to use the correct tools and overall best practices. Learn more about how to cut metal panels.

Safety Precautions

Before cutting your metal panels, take appropriate safety precautions to avoid getting hurt. Use gloves to protect your hands from being cut by the sharp metal panel edges. If metal filings fall on the surface of your metal panel, try to blow them off instead of touching them with your hands. Put on safety goggles to protect your eyes from airborne metal filings.

Tools

To avoid damaging the panels or their coating, it’s important to use proper tools. Snips are generally recommended for trim work while shears and nibblers are used for the panels themselves. Some of the best tools to use include:

● Aviation Snips: Good choice for small cuts, including cuts near pipe penetrations.
● Electric Shears: Ideal for lengthier cuts along steel.
● Mechanical Shears: Add-on tool that fits into an impact or screw gun. Ideal for use on standing seam panels at hips and valleys.
● Nibblers: Also known as turbo shears, they’re ideal for cutting openings for windows and doors.

Skill saws can also be used if this is the only resource available. Be sure to use a blade that is specifically designed for metal panels. Turn the panel upside down so that the painted side is facing the ground to make sure filings don’t stick to the paint coating.

Avoid Using:
● Torches
● Cut-Off Saws
● Reciprocating Saws
● Hacksaws
● Grinders

These tools heat up the metal panel and can melt or damage the edge that was cut. They can also cause metal filings to go airborne, creating a safety hazard. If those metal filings stick to the panel’s painted coating, they can cause surface rust.

Cutting Metal Panels

Marking the Panels

Before cutting your panels, be sure to measure and mark the cuts you’re planning to make. To mark your panels, lay them down flat with the painted side down. Make sure the panel is stable by clipping the panel in with c-clamps.

Do not mark on the finished side of the panel to avoid marring the visible surface. Avoid using a pencil with graphite lead as this is a dissimilar metal and could cause your metal panel to corrode. Instead, use a chalk line or magic marker. Use a straightedge or combination square to draw a straight line.

Cutting Technique

Before making a cut, be sure to line up the snip blade with the marking. Keep the blade perpendicular to the metal sheet you’re cutting. Work slowly and make steady and consistent cuts for smoother lines. Keep your cuts short to avoid jagged edges. For quicker, straighter cuts, use nibblers or mechanical shears.

Improve Efficiency by Planning Ahead

Cutting metal panels and trim in the field is easily one of the most time-consuming parts of the installation process. To avoid extra cutting in the field, it’s important to create an accurate materials list upfront. To do this, plan out how your panels will cover the roof or wall areas. Make sure the coverage width and count of the panels ordered is sufficient to cover the area you are installing. Consider which side of the building you will start with and how the ends of the wall or roof will be finished. It is possible that you may be able to avoid splitting a panel lengthwise if you do proper calculations in advance. Additionally, some panels are only able to be installed in one direction. Next, review the standard trim details such as valleys, hips, and around doors and windows. Be sure you have appropriate panels to cover these areas as well, and order to the closest pre-cut length available.

Tips for Installing Metal Roofing Accessories

Posted on June 24, 2020May 31, 2023 by Tyler Roose

A properly-installed metal roof is expected to last 60 years or longer. However, incorrectly-installed roofing accessories can cause serious damage and decrease the life of your metal roof. The key to a long-lasting metal roof is correctly selecting and installing metal roofing accessories.

Considerations

When selecting and installing metal roofing accessories, it’s important to consider several factors.

Type of Construction– Consider the roofing substrate when selecting accessories. The fasteners used for installation will vary depending on the material that the panels and trim are attached to, such as framing or plywood sheeting.

Geometry of the Roof– When examining the geometry of the roof, look for symmetry and protrusions. If the roof has a chimney, skylight or other feature, flashing will be necessary to prevent leaks.

Roof Pitch & Slope– Since each panel profile channels water differently, it’s important to consider the slope and pitch of your roof when selecting metal roof panels. The recommended trim and accessories will depend on the panel profile selection.

Next, you can consider the aesthetic appeal of the available panel profiles and accessories for your building project.

Selecting Metal Roofing Accessories

Once you’ve examined your roof and selected the appropriate panel profile, you can choose metal roofing accessories to go with it. Each panel series has specific installation resources with a product checklist that outlines the standard accessories that should be used.

Installing Metal Roofing Accessories

When installing metal roofing accessories, it’s important to use caution when penetrating the roofing panels and select compatible materials. In most cases, the roofing contractor will be responsible for proper installation. All penetrations should be added to the project specifications and approved ahead of time by the roofing contractor.

Our manuals recommend detailed accessory installation instructions for each of the roof conditions mentioned above down to the trim, sealant and fasteners. For the longevity of your metal roof, it’s crucial to follow the standard details for your roofing conditions. Make sure to use the equipment offered by your manufacturer to preserve the weathertightness warranty.

Here are some things to avoid when installing metal roofing accessories:

Using dissimilar materials – Accessories made of dissimilar materials such as lead, copper and graphite can cause damaging reactions and corrosion.
Penetrating the roof before coordinating with the roofing contractor – To maintain the weathertightness warranty, all pipe penetrations should be coordinated with the roofing contractor.
Choosing the wrong clip for your insulation thickness – There are several different clip systems available that vary depending on the roof substrate.
Using an abrasive saw – Make sure to use the recommended tools. Using an abrasive saw could damage the cut edge, causing premature corrosion to the panel or trim, and likely damaging the paint system. This will void any finish warranty and create a potential spot for the roof system to leak. Instead, use snips or hand shears.

How To Prepare for Metal Roof Installation

Posted on May 11, 2020May 31, 2023 by Pat Thostenson

Metal Roofing Installation Prep

If you’re looking to replace your current roof, metal roofing is a durable, low-maintenance alternative to asphalt shingles. To make the most of your investment, it’s important to plan ahead for the metal roof installation process. Learn about the steps that you and your contractor should take to prepare for metal roofing installation.

Consider Metal Roofing Options: Profiles, Gauge, Color, Etc.

Consult with a local distributor to select metal roofing materials for your building project. They’ll be able to provide resources such as product information, color charts, technical literature and product samples.

There are several factors to consider when selecting metal roofing panels. The most important consideration is the roof pitch. Make sure to choose a metal panel profile that will perform best with the pitch of your roof in order to keep it weathertight. Once you’ve selected the panel style, choose from a variety of profiles and colors depending on your budget and aesthetic preferences.

For residential applications, the Imperial Rib® panel, an exposed fastener panel, offers rustic charm. The SL-16® panel, a concealed fastener panel, provides a clean, sleek aesthetic.

Choose a Contractor

Next, you’ll need to select a contractor. During this process, it’s important to choose a contractor that has experience installing metal roofing. In many cases, your local distributor can provide references to narrow down your search.

Building Owner Prep Work

Although the contractor will be responsible for most of the heavy lifting, there are a few things you should do to prepare for metal roof panel installation.

Clear the Space

Make sure to clear the space around your home or building to prepare an adequate workspace for your contractor. For commercial properties, you may want to set up barriers to keep your customers safe. For residential buildings, you should remove items from the yard, patio, deck or balcony to keep them from being damaged. Consider protecting landscaping that’s in close proximity to the building by covering it with a tarp.

Alert Your Neighbors

As a courtesy to your neighbors, consider warning them about the loud noises that will likely occur during the metal roofing installation process.

Make Arrangements

Make arrangements for any individuals that may be disturbed by the noise. For residential buildings, you should also make arrangements for pets that may need to go outside during the day.

Contractor Prep Work

Measure the Roof & Create a Materials List

Once you’ve hired a contractor, they’ll begin their prep work by measuring the roof to create a materials list and determine order quantities. This list should contain all of the necessary materials including:

Panels
Trim (Edging)
Screws
Closure Strips/Closures
Venting Material
Other Roofing Accessories

Before the materials list is finalized, you should discuss with your contractor whether or not to vent the ridge cap. In residential situations, this is necessary to circulate air throughout the house.

Order Materials

In most cases, your contractor will be responsible for ordering the roofing materials through the local distributor. Before the order is placed, consider which warranty option is best for you. While a 40-year warranty is the most common choice, some of the lighter gauge materials offer a 20-year warranty option.

Inspect Material

Once the roofing materials are delivered, it’s important to inspect them. Your contractor should do the following:

Check the bill of lading to make sure that all materials have been delivered
Check the materials for damage including dents and scratched paint
If something is wrong with the order, contact the distributor to order replacement materials

Remove Old Roofing and Repair Damage

Remove the existing roofing down to the decking. After the existing roofing materials have been removed, the installer should check for bad decking and make any necessary repairs. All ice and water shields and underlayment should be removed and replaced as well.

Metal Roofing Installation

After all of the prep work is completed, the metal roof installation process can begin. During the installation process, it’s important to communicate with the main contact for your project about any concerns you may have. Once the installation process has been completed, make sure the work is done to your liking. Be sure to finalize payment and warranty information as well.

Metal Roofing and Hurricane Season Part 1: Securing the Roof

Posted on June 11, 2019May 31, 2023 by Marc Carolan

For customers who live and work in coastal areas, preparing for hurricane season is vital. This preparation helps mitigate the risks and damage tropical storms can cause to their homes and businesses. Most hurricane-preparedness tips include making a hurricane emergency kit, reviewing insurance policies and outlining family emergency and evacuation plans. While these are all important activities, there are few that focus on the impact roofing material can have on the safety and security of your customers and their property. In this two-part blog series, we’ll evaluate the performance of metal roofing in coastal areas and provide practical tips to help your customers protect their assets during storms.

First, we’ll review one of the most vulnerable parts of your customers’ structure: the roof. Roof cover damage accounts for most non-storm-surge-related insurance claims during a hurricane. Damage to this vital building element can be dangerous and devastating since even partial damage can leave the entire structure vulnerable to wind, water and other structure- and property-damaging elements. To help prevent these ill-effects, selecting a roof material that can stand up to tropical weather is essential.

Metal Roofing Performance in Coastal Communities

Metal roofing is made of interlocking panels that provide unique strength and durability. When properly installed, some can withstand abuse from hurricane-force winds up to 140-mph as well as wildfires, hailstorms and tornadoes. American Building Components (ABC) metal panels feature UL 580 Class 90 Wind Uplift Resistance, UL Class 4 Hail Impact Resistance and Class A Fire ratings to support this. Metal roofs also have fewer seams as compared to traditional asphalt shingle roofing. Fewer seams means fewer entry points for water that can soak attic insulation and cause ceiling collapse and other damage.

Many metal roofing panel profiles adhere to strict approval codes designed to prevent property loss and damage from high winds. One example is the Miami-Dade County Approval—one of the most stringent building codes in the industry. To help your customers meet these strict requirements, panels like ABC’s PBR and 5V Crimp profiles, as well as most insulated metal panels can be specified to qualify for Miami-Dade County-approval. To ensure your customers’ roof adheres to Miami-Dade standards, be sure that the panel meets guidelines for thickness and features a Miami-Dade approval sticker. Even if a Miami-Dade approved panel is used, if not installed properly using correct fasteners, it will not be effective. Remind your customers that the manufacturer’s installation instructions should provide all necessary details to ensure proper function and protection.

The True Savings of Metal Roofing

By choosing metal roofing, your customers can save money in the long run. Although other roofing options are cheaper up-front, customers who install metal panels benefit from their superior design and durability. This pays dividends in the form of lower maintenance costs and insurance premiums over the life of their metal roof. A properly-installed, thick-gauge metal roof can last up to 50 years. That’s more than double the lifespan of traditional asphalt shingle roofs many customers are familiar with. In addition, some manufacturers back the durability and lifespan of their metal roofing products with industry-leading warranties that provide peace-of-mind.

How to Prevent Ice Dams on Metal Roofs

Posted on January 10, 2019May 31, 2023 by Ken Buchinger

Those in areas prone to below-freezing temperatures are likely familiar with ice dams and the costly damage they can cause. With winter weather already upon us, it’s important to ensure your building is protected against the dangerous and expensive effects of ice dams.

What Causes Ice Dams to Develop?

Most ice dams are a result of building air barrier flaws. When warm indoor air escapes through a rooftop, it warms the roof sheathing. This rise in temperature melts the underside of the layer of snow on top. The melted snow then moves down the slope of the roof toward the eaves, where it freezes into ice. As this process continues, the ice thickens, resulting in ice dams. These obstructions can cause water to back up and form a reservoir that can damage ceilings.

How Can Ice Dams Be Prevented?

To prevent ice dams, follow these four steps:

Seal Air Leaks: Sealing air leaks between the warm building interior and the attic or ceiling is imperative to prevent increased sheathing temperatures that can lead to ice dams. If your roof leaks every winter, it’s likely that an air leak is to blame. And, getting a new roof is not likely to help—even if it features more ventilation. The simple way to determine if you have air leaks is to get into your attic and check. Leaks can likely be easily sealed with two-component polyurethane spray foam. And extending any exhaust fans that don’t reach outside can help adequately seal the structure.

Ensure Proper Insulation: Many buildings don’t have adequate insulation levels to prevent ice damming. Building codes based on your geographic location can help you determine how much insulation you need. If the structure’s design doesn’t allow for adequate insulation, we recommend installing as much closed-cell spray polyurethane foam as possible. If replacing your roof, you can also install additional rigid foam insulation on top of the existing roof sheathing before you install the new roof. When taking that approach, make sure all products used are compatible with your new roof and adhere to manufacturer’s recommendations. It’s also imperative that attic insulation completely covers the top plates of a building’s exterior walls.

Improve Ventilation: Improving ventilation alone will not prevent air leaks that cause ice damming and should never be your first or only defense. In fact, improving ventilation without sealing air leaks and installing adequate insulation can increase heating costs and make ice damming problems worse. Despite this, if combined with steps one and two above, addressing your roof ventilation can’t hurt. The best ventilation options include soffit and ridge vents. It’s important to remember that all attic ventilation systems require an insulation dam (blocking) between the trusses and ventilation baffles at the attic’s perimeter, facing the soffits, to maintain a ventilation channel from the soffit to the attic and protect against wind-wash.

Use Underlayment: Covering your roof sheathing with two or more layers of rubberized membrane underlayment is another protection method that is far less effective if not used in concert with steps one and two. To use properly, it should extend from roof eaves to a point that’s three feet higher than your exterior wall.

Additional measures like framing your roof with raised-heel trusses can also help prevent ice dams. Additionally, avoiding including valleys as well as gutters that are at or above the roofing plane is ideal. Taking these steps can help ensure people and property are safe from overhead dangers. This should be a priority when designing, installing and maintaining your metal roof.

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

Posted on November 13, 2018May 31, 2023 by Ken Buchinger

Additional considerations for working with metal panels in winter.

In part one of our series on metal roofing and snow, we covered five of the most important elements to consider when preparing structures for winter weather. In this post, we’ll review four more ways to prevent unexpected, costly damage of metal panels in winter.

Consider roof material and surface color

Metal roofs absorb heat quickly and radiate it effectively. Darker panel colors can enhance this solar absorption effect, which can save you money year-round. But because UV light can pass through 3-5 inches of snow, when combined with heat loss through the roof, it becomes more difficult for snow to stay solid. To minimize the chance of ice damming, you should ensure your roof system is properly sealed and insulated. If not, ice damming may occur and the melting and re-freezing of snow throughout the day can result in icy layers that promote snow sliding—no matter the roof material or color.

Review weathertightness factors

For low-sloped roofs (less than 3:12), it is especially important for panel seams to be watertight to prevent water (melted snow) from leaking into the structure. This can be problematic when snow gathers and stays on a roof. Architects, designers and specifiers, therefore, should consider using panels that have passed the ASTM 2140 water head test or FM 4471 Appendix G water test. Water-resistant underlayment should also be considered for all roof slopes.

A close-up of this dormer roof illustrates how the impact of sliding ice and snow can damage panel seams.

Consider your roof layout

Design elements like valleys and slope changes cause snow to collect and increases your snow load. Also, when dormers extend from a large roof area and one area is significantly bigger than the other, the structure is susceptible to experiencing unbalanced sliding snow. This imbalance can actually tear open standing seams and displace panels. Also consider that drifting snow may accumulate behind HVAC units, at perimeter walls, and behind solar and photovoltaic (PV) panels.

Ensure Proper Roof Maintenance

One of the best ways to prevent snow and ice issues is to regularly inspect and maintain your roof. In addition to cleaning and inspecting your roof for possible issues, properly removing standing snow and preventing ice dams is a vital part of avoiding damage to your metal panels in winter. This often requires that you get into your attic to inspect for air leaks—the leading cause of ice dams. Read more about how to properly maintain and remove snow from your roof in this blog post.

If an issue is discovered, consult your roofing material manufacturer for recommendations as well as advice on warranty claims. Additionally, you can reach out to a trusted roofing professional in your area. These professionals can thoroughly inspect your roof system to help you determine ways to rectify any potential issues. You’ll want to do this before damage and/or injury occurs and before you pay for sub-par or ineffective repairs.

If you missed part one of this series, click here for our top five considerations. These include managing snow load and sliding snow, preventing ice dams, using retention systems and more!

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

Posted on October 4, 2018May 31, 2023 by Ken Buchinger

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:

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.

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.

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.

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.

Protect Roof Attachments

This pipe penetration is protected from sliding ice and snow by a small section of S-5! ColorGuard to the panel seams immediately up-slope from the pipe.

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

Posted on July 26, 2018May 31, 2023 by Marc Carolan

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

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

Posted on June 28, 2018May 31, 2023 by Tyler Roose

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.

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.
