Rmax TSX-8510 is an energy-efficient thermal insulation board composed of a closed-cell polyiso foam core bonded to glass fiber reinforced aluminum foil facers on both sides. The exposed side of the board has a heavy, embossed 12mil facer with a white modified acrylic coating. The other side is marked in production to ensure proper installation.

Just like TSX-8500, this product is designed for use without a thermal barrier (up to 4.5” on walls or 12” on ceilings) to provide an attractive interior finish.
