What are Insulated Plasterboards?

The 112.5mm XT/TL-MR insulated plasterboards ( 100mm insulation + 12.5mm Moisture plasterboard ) combine plasterboard with an integrated insulation layer, typically PIR foam. This bonded construction creates a single multi-purpose panel offering both thermal performance and a finished surface. These panels improve thermal and sound insulation, whilst streamlining installation timescales. Common applications include walls, ceilings, and floors, with options available in various sizes and thicknesses to match specific building needs.
