THERMAX™ Metal Building Board and Sheathing have a reflective aluminum-foil facer to slow radiant energy

Reveal the Efficiency Within

It’s no secret: Rigid foam insulation from Dow installed in THERMAX™ Metal Building Board and THERMAX™ Sheathing, with an R-value of 6.5 at 1", have a reflective aluminum-foil facer to slow the radiant energy through the roof surface. They also provide excellent heat flow characteristics, especially when used in conjunction with standing seam roofing. Both can be used on concrete or metal decking.

STYROFOAM™ Brand Square Edge Insulation provides exceptional water resistance, thermal performance (R-value of 5.0 per 1") and high compressive strength (25 psi). It is an ideal choice for over concrete or metal decks with covers of membrane and standing seam.

For continuous protection against air and moisture, don't forget FROTH-PAK™ Foam Insulation and GREAT STUFF PRO™ Gaps & Cracks Insulating Foam Sealant.
