STYROFOAMâ„¢ Brand WALLMATEâ„¢ Insulation is designed as a quick, easy-to-install and durable option for insulating interior basement walls and other areas of the home. When butted together, slotted "rabbet" edges on long edges form a slot between the extruded polystyrene foam boards to accommodate a wood nailing strip, which is used for attaching the boards to the basement wall or ceiling rafters. It also provides a nail base for drywall.
Building Code Compliance
Complies with ASTM C578 Type X. Meets CAN/ULC S-701 Type 2 and CCMC 12083-L. Meets IBC/IRC requirements for foam plastic insulation. See ESR-2142, BOCA-ES RR 21-02, ICBO-ES ER 2257. UL Classified, see Classification Certificate D369. Calif. Std. Reg. # CA T064. Florida Building Code FL 3835.

(1) Not all product sizes are available in all regions. (2) R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2• h•°F/Btu. R-value determined by ASTM C518. (3) Vertical compressive strength is measured at 10% deformation or at yield, whichever occurs first. |
