About This Product
The Sika Rmax ISO R-13.1 2 in. x 4 ft. x 8 ft (32 sq. ft.) Pro Select R-Matte Plus-3 Rigid Foam Board Insulation, like other Sika Rmax Pro Select R-Matte insulation boards, is a versatile, high-performance foam panel designed for a wide range of interior and exterior applications. Featuring a durable, non-glare white reinforced aluminum facer on one side and a reflective aluminum facer on the other, these boards provide both thermal and radiant insulation benefits.
Ideal for use in stud walls, cavity walls, masonry, stucco systems, attics, crawl spaces, foundations, and more, this ENERGY STAR® qualified insulation delivers an R-value of 13.1 in a 2 in. x 4 ft. x 8 ft. panel. Lightweight and easy to handle, it’s a practical solution for both professional and DIY projects requiring reliable, non-structural insulation.
