Celotex 37.5mm Thermal Laminated Insulated Plasterboard 2400mm x 1200mm x 37.5mm PL4025

Celotex 37.5mm Thermal Laminated Insulated Plasterboard 2400mm x 1200mm x 37.5mm PL4025

The Celotex PL4025 Thermal Laminated Insulated Plasterboard combines thermal insulation with drylining in one easy-to-install board. At 37.5mm thick (25mm PIR insulation bonded to 12.5mm plasterboard), it is designed to provide excellent thermal performance while also creating a smooth surface ready for finishing.

This board is ideal for internal wall and ceiling applications where insulation and a plaster finish are required in a single product. It helps reduce heat loss, improves energy efficiency, and saves installation time compared to fitting insulation and plasterboard separately.

• Standard 1200 x 2400mm boards


• 25mm PIR insulation bonded to 12.5mm tapered edge plasterboard


• Paper facing


• BBA approved – certificate 16/5357 (Plasterboard Thermal Laminate)


• Improves energy efficiency and reduces heat loss
