What are Insulated Plasterboards?

The 47.5mm XT/TL-MR insulated plasterboards (35mm insulation + 12.5mm moisture resistant plasterboard) combine plasterboard with an integrated insulation layer, typically PIR foam. The insulation bonds directly to the plasterboard, creating a unified panel that provides both thermal performance and a finished surface. These panels improve thermal and sound insulation while streamlining installation. They suit walls, ceilings, and floors in various thicknesses to match specific building needs.
