Insulated Sheathing Applications
ThermalStar® Siding Underlayment and ThermalStar® XTR™ provide insulation, as well as backer, for siding or stucco. Since these products offer a continuous insulative barrier, they eliminate thermal bridging — a common source of lost energy in a building. The ThermalStar® product line includes products used in a wide variety of exterior, interior and cavity wall applications.

 

Versatile, lightweight ThermalStar® rigid insulation installs easily and offers higher, long-term R-value, exceptional moisture protection and termite resistance. Many of the products in the ThermalStar® product line are available in a variety of compressive strength grades — from 10 psi all the way up to 60 psi!
