Key Benefits of using Roofing Insulation
Choosing the right roofing insulation is essential to building performance, long-term savings, and occupant comfort. At All Star Foam Inc., our high-quality EPS roofing insulation products are engineered to deliver efficiency, durability, and protection for both new builds and retrofits.
Energy Efficiency
Proper insulation can significantly reduce heating and cooling costs by maintaining optimal indoor temperatures.
Durability
High-quality materials ensure long-lasting performance and resistance to environmental factors.
Moisture Control
Effective insulation prevents condensation and moisture buildup, protecting the roof structure.
The Perfect Solution Roofing Insulation
EPS roofing insulation plays a critical role in enhancing the thermal performance, durability, and energy efficiency of a building. Here are some of the most common and valuable ways it’s used across industries and project types:
-
Commercial Flat Roofing Systems
EPS insulation is widely used in low-slope or flat roof assemblies on commercial buildings like office complexes, retail stores, schools, and hospitals.
-
Residential Homes
For pitched or flat residential roofs, EPS sheets and foil-faced panels help reduce thermal transfer, lower heating and cooling costs, and add comfort in homes year-round.
-
Roof Retrofits & Re-Roofing Projects
EPS fan fold or sheet insulation is frequently installed during roof replacement or retrofits to provide a new thermal barrier without tearing off the entire roof.
-
Metal Roof Systems (Flute Fill)
EPS flute fill is used to level the gaps in metal decking prior to applying membrane or rigid insulation, creating a smoother and more efficient roofing assembly.
-
Drainage Control Around Roof Features
EPS roofing insulation supports energy-efficient envelope designs in large-span buildings where climate control and utility savings are essential.
Using EPS flat sheets from All Star Foam has significantly improved the way we approach roof insulation on our commercial builds. The sheets are lightweight, easy to handle, and provide exceptional thermal performance, helping us meet energy codes without adding extra structural load.
Frequently asked questions
Our standard EPS insulation boards come in sizes like 4’x8’ and 2’x8’, with thicknesses ranging from ½” to several inches, depending on your R-value requirements. We also offer custom-cut tapered panels, crickets, and flute fill pieces to meet the exact specifications of your roof design.
Need something specific? Just send us your plans and we’ll fabricate it to fit.
The required R-value depends on your climate zone, local building codes, and type of roofing system. For example, a flat commercial roof in New Mexico might require an R-30 or higher, which translates to roughly 6–8 inches of EPS insulation. Our team can help you determine the best thickness for your project.
We sell directly to contractors, roofers, builders, and property owners. Whether you’re managing a large commercial project or a small residential retrofit, we’re happy to work with you and offer volume pricing for larger orders.
Fast local fabrication means you get what you need—when you need it.
We have in house inventory for all your roofing projects. Custom orders usually take a few days, depending on inventory and customization needs. For larger or highly custom tapered systems, lead times may vary—but we always strive to meet your project schedule.
Need it sooner? Give us a call—we’ll do our best to expedite it!
Yes! EPS insulation is suitable for new construction, retrofits, and re-roofing applications. Products like fan fold and flute fill are especially useful for upgrading insulation without a full tear-off.
You can improve energy efficiency and drainage without rebuilding your entire roof system.
