1-1/2 in. x 4 ft. x 8 ft. R-10.3 ECOMAXci® Fire-Resistant Ply Thermal Polyiso Insulation Board | FMP2.1-EBCI58-48-RM

Rmax's ECOMAXci® FR Ply Thermal Polyiso Insulation Board simplifies continuous insulation installation by combining insulation and sheathing in a single panel. Its rigid polyiso core reduces thermal bridging, improves energy efficiency, and helps maintain consistent interior temperatures. The fire-rated plywood face ensures strength for fastening exterior cladding, while the board's dimensional stability resists warping and moisture-related expansion. This all-in-one system streamlines construction workflows and enhances long-term building performance.

• Applied to wood or metal framing with the wood to the exterior in order to provide a conti nuous layer of thermal insulati on and a suitable substrate for the mechanical att achment of many diff erent kinds of cladding systems
• Laminated to 5/8 in. fire-rated plywood for structural support
• Rigid polyiso core reduces thermal bridging in wall assemblies
• Lightweight, uniform panels for fast, easy installation
• Suitable for commercial and residential exterior wall applications
