Unilin FR/TP 26mm Flat Roof Insulation Board

The Unilin FR/TP 26mm is a composite thermal panel engineered for flat roof applications, featuring a 20mm polyisocyanurate (PIR) core bonded to 6mm WBP plywood decking. This integrated design delivers both insulation and structural support in a single product, eliminating the need for separate installation steps. The composite construction incorporates foil facings on both surfaces, creating a gas-tight barrier that enhances thermal performance and weatherproofing capabilities.

The 26mm Unilin FR/TP was previously known as 26mm Xtratherm FR/TP.
