Rmax ECOMAXci FR Air Barrier is a high-performance insulation board designed for exterior walls that demand energy efficiency, durability, and reliable air control. Built for builders, contractors, and homeowners who want fewer hassles on site, this board blends strong insulation with a robust exterior facing for long-lasting performance.

Key Features & Design

• Core & Facers: Closed-cell polyisocyanurate (polyiso) foam core bonded to glass fiber reinforced aluminum foil facers on both sides.
• Durability & Fire Performance: Glass fiber reinforcement on both faces for enhanced durability, dimensional stability, and fire performance.
• Exterior Surface & Protection: Printed side, exposed to the exterior, has a robust embossed 12mil facer with an aluminum reflective surface and clear coating for limited protection against oxidation ensuring Jobsite security and enhanced radiant heat protection.
• Size & Availability: 4 ft x 8 ft sheets with thicknesses from 0.75" to 3.5" (see table for pallet quantities).
• Thermal & Air Barrier: Energy-efficient thermal insulation board that helps reduce air leakage and thermal bridging on exterior walls.
