DCT Thermalcheck XPS Insulated Plasterboard


Designed to facilitate fast installation of plasterboard liner and thermal insulation simultaneously, DCT Thermalcheck consist of extruded polystyrene  thermal insulation pressure bonded to gypsum plaster board. This economic, easily installed lining system allows you to insulate and line walls in one simple operation, using normal fixing methods. Suitable for stud, brick and masonry walls and ceilings, DCT Thermalcheck has a high compressive strength and moisture resistance, providing unique thermal insulation properties.

DCT Thermalcheck is lightweight and can be easily installed using the same fixing methods as ordinary plasterboard. The need for battens and separate insulation is eliminated, thereby speeding up construction time and providing a durable internal lining system. No special tools are required, as boards can be cut using standard handtools.

Renovating an older home becomes less of a challenge now that DCT Thermalcheck provides a fast, trouble free method of plastering and insulating walls and ceilings, including suspended ceilings.

DCT Thermalcheck provides unrivalled resistance to water vapour or moisture, thereby solving problems with slightly damp areas, such as bathrooms.

An extremely effective thermal insulator, DCT Thermalcheck insulated XPS board’s high insulating properties will assist in maintaining controlled temperature conditions for the life of your home.
