GDeck Insulated Flooring

Gdeck Insulated Flooring

The Gdeck EPS Panel System is a revolutionary new way to insulate ground floors. The system comprises of Longley prestressed concrete beams and Gdeck EPS insulation panels. The silver infill insulation panels provide high thermal performance which are then combined with high density white EPS rails which gives the floor its strength. Unlike competitors’ flooring solutions, the Gdeck system does not require any additional sheet insulation, thus significantly reducing installation time.

EPS Infill Blocks & Load Bearing Rails

The EPS infill blocks and load bearing rails enable a floor to meet the design U-values specified in the documents supporting the Building Regulations and can contribute to minimising the risk of interstitial and surface condensation in floors.

The blocks and rails are stable, rot-proof and durable and will remain for the life of the building in which it is installed.
