RAISE YOUR EXPECTATIONS OF
BELOW-GRADE INSULATION
RMAX® BELOW GRADE INSULATION FOR EXTERIOR WALL AND FOUNDATION
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
The tools you need to get the job done.
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
