Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tapered EPS is a cost-effective way to build slope into a low-slope roof, and the 1.25 pcf C6 density is a common choice under single-ply systems. Order the taper slope (e.g., 1/8 in. or 1/4 in. per foot) to match your drainage plan and confirm the membrane manufacturer allows EPS in your assembly. Store panels flat and off the ground, protected from sunlight, until installation.
EPS is combustible; keep heat, open flame and hot work away from exposed panels and follow FM/code requirements for the covering assembly.
Order InsulFoam C6 tapered EPS roof insulation today and build slope that lasts.
