The beauty is in the details.

BTRboard™ features a medium density polyurethane fire-rated Class 1 foam, creating a monolithic bond to the sheathing substrate. The interior surface can be finished with either fir veneer or fiberglass facer, both of which offer superior resistance to moisture and biological growths such as mold. The final material thickness is 1 ⅝ inches with fir veneer and 1 ½ inches with fiberglass facer.

Introduction

BTRboard™ is an innovative, patented insulated sheathing panel designed to enhance the insulating value of standard wood frame sheathings. With an insulation value of up to R-8.35, these structural panels effectively integrate thermal protection, significantly improving the insulation value of studs, which typically represent the lowest insulation point in a wall assembly.

BTRboard™ is tailored for wall applications and can replace traditional substrates such as OSB, plywood, and drywall.

Installation

BTRboard™ is installed in the same manner as traditional sheathing. Since the finished frame wall presents a similar surface to a conventional wall, the installation of sheathing membrane and cladding can proceed as usual, ensuring compatibility with standard construction practices.

BTRboard™ utilizes existing certified structural sheathing components, ensuring the highest quality in the final panels. This product offers a significant enhancement in insulation and structural integrity for modern construction needs.
