Roofing crew placing Insulfoam EPS panels on a commercial roof

For Commercial Roofing Contractors

Lower installed cost on your next commercial roof.

Lightweight EPS from Insulfoam can go down in one layer, up to 40 inches thick, or in much fewer layers compared to stacked polyiso or XPS. Less material, faster installs, less labor, stable R-value.

Up to 30% less than full polyiso systems
Lightweight and easy to install, so crews finish faster
Stable R-value; 100% 20-year thermal performance warranty

Where EPS cuts cost and install time

Four commercial roof assemblies where EPS does the work of stacked polyiso or XPS.

METAL ROOF RECOVER

Flat, code-compliant surface in one pass

Insulfoam FL flute fill is factory-cut to the metal profile, so the new membrane goes over a smooth surface with no added insulation needed.

INSULFOAM FL →

FLAT ROOF RECOVER

About 20% less than 1-inch polyiso

R-Tech panels and fanfold bundles go under single-ply membranes with no slip sheet. Fanfold cuts material handling time by 60% or more.

R-TECH FANFOLD →

TAPERED ROOF

Up to 30% less than full polyiso tapered

Factory-cut to any slope, up to 40 inches thick, with crickets, saddles and sumps built in. Usually one layer, so crews skip the stack.

INSULFOAM EPS TAPERED →

HYBRID ROOF (EPS & POLYISO)

Double-digit savings per square foot

EPS as the fill layer under a top layer of polyiso: code-required R-value with a fraction of the polyiso.

"Cost was one of the biggest reasons we went with EPS insulation. Whenever you can save on insulation and get the same R-value, that’s a huge benefit. EPS also led to labor savings, as the insulation is easy to use and easy to cut."

James Fiscus, Estimator, Capitol Roofing Service, Sandy, Utah

New to EPS, or haven’t looked in a while?

While polyiso is often specified, here are three things that set expanded polystyrene (EPS) apart on commercial roofs:

Fewer layers, up to 40" thick

EPS is factory cut to specified thickness and slope, enabling crews to install fewer layers or a single layer, more quickly.

98% air, easy to install

Panels are light enough to load from the ground and easy to cut on the roof, so fewer hands place more insulation.

R-value that stays put

EPS holds its R-value with no thermal drift, and is eligible for a 20-year thermal performance warranty.
