WATER CAN’T RUFFLE OUR FEATHERS

With its strong conductivity, water can significantly undermine the thermal effectiveness of insulation. However, the closed-cell structure and impermeable matrix of Rmax® Below Grade foam board resists water absorption, making it an ideal selection for below-grade uses. To that point, it meets ASHRAE 90.1 below-grade water absorption requirements, demonstrating
0.3% max water absorption per
ASTM C272.

WHY RMAX® BELOW GRADE

• High R-Value per Inch

• High Compressive Strength

• All-Around Protection

• Familiar Installation Method

• Thinner Profile

• Water Resistant

LESS MATERIAL.
LESS IMPACT.

Reduce Environmental Impact with Polyiso.

HIGHER R-VALUE allows for less volume of material needed. Insulating with Polyiso, instead of XPS means:

25% FEWER Truckloads/Trips
to the job site for the same square foot of wall

25% LESS Volume of Material
needs to be produced for the same square foot of wall

25% LESS Floor Space
for the same turnover in distribution/use of floor space
