Roofing Recover Board

Insulation is a vital component of a building’s envelope and contributes to the overall energy efficiency performance. For building designers requiring the highest quality rigid insulation, ThermalStar® Laminated Roof Insulation (LRI) has been designed specifically for recovery board applications with factory-applied film facings that are compatible with single-ply membrane roofing systems.

ThermalStar LRI can be applied directly over existing roof membranes and structural roof decks providing a one-step recover board insulation resulting in reduced material and labor costs of roofing.
