76mm Unilin FR/TP Flat Roof Insulation Board

The 76mm Unilin FR/TP is a composite insulation panel engineered for flat roof applications. It features a 70mm polyisocyanurate (PIR) core bonded to 6mm WBP-grade plywood, delivering both thermal performance and structural decking capability. This integrated design eliminates the need for separate insulation and decking layers, streamlining installation on new builds and refurbishment projects.

The 76mm Unilin FR/TP was previously known as 76mm Xtratherm FR/TP.
