THERMAX™ Sheathing is a nonstructural, rigid board insulation consisting of a glass-fiber-infused polyisocyanurate foam core laminated between two 1.0 mil, smooth, reflective aluminum facers. The glass-fiber reinforcement contributes to improved fire …

2018年12月8日 · My recollection is that you generally want to insulate to the ground and then insulate on the ground for a couple of feet next to the foundation. Poly ISO is better performing per inch but XPS is likely fine for this application.

Thermax ™ Metal Building Board. A polyisocyanurate foam core with an embossed aluminum foil facer on both sides. These aluminum foil facers serve to dampen the noise resulting from the system’s movement when outside temperatures change. Available from 1/2″ to 4-1/4″ thick. Can be installed exposed to the interior without a thermal barrier.

THERMAXTM Sheathing is a non-structural, rigid board insulation consisting of a glass-fiber-reinforced polyisocyanurate foam core laminated between 1.0 mil smooth, reflective aluminum foil facers on both sides. The glass-fiber reinforcement, along with chemical modifications, contributes to improved fire performance and dimensional stability.

Thermax™ NH Insulation Series features: • Class A, non-halogen, safer-by-design formula • Consistent, high-performance R-value at both 75°F and 40°F
