About Envirostrap Rigid foam Insulation

Envirostrap is a rigid insulation board made from closed cell Expanded Polystyrene (EPS) with three integrated furring strips on one side. This highly effective combination of materials offers a 2-in-1 solution incorporating insulation and finish attachment surfaces that can be used for both above grade and below grade interior applications. The furring strips can either be fully recessed inside the foam for interior finish installation or can protrude from the surface of the foam by ¾” (19mm), creating an air gap that is needed for exterior cladding installation.

The three furring strips are located every 16” (406mm) on each panel and are 2.5” (63mm) wide and make for an easy installation of finishes such as siding or gypsum board (drywall). The combination of the thicker strips (1” (25mm)) with the spacing and width provides the user with the widest range of warranty compliance by the various siding manufacturers.

Envirostrap

The furring strips are made from plywood in order to eliminate bowing and warping that can be found in typical dimensional lumber. For instances where wood cannot be used due to potentially increased moisture issues, the panels can be ordered with plastic strips giving the user excellent flexibility.
