Details

Celotex PL4025 is a high-performance insulated plasterboard designed for trade professionals who require efficient, reliable internal wall insulation combined with a quality plasterboard finish. This product is tailored for builders, site managers, and contractors working on both new builds and refurbishment projects where thermal performance and installation speed are priorities.

Application

Celotex PL4025 is suitable for dry-lining applications where thermal insulation and plasterboard are needed in one solution. It can be mechanically fixed or adhered to timber frame studs, masonry walls, and cavity walls to upgrade thermal efficiency.

The aluminium composite facing also acts as a vapour control layer, contributing to condensation risk management when installed according to BS 5250 guidelines.
