A pre routed, cement coated XPS panel, for use with water based underfloor heating systems.Our overlay panels are manufactured from high density XPS 300kPa which is thermally insulated, waterproof and covered with a reinforced cement coating. The panels provide a quick and easy solution for the placement of pipework when doing a retrofit installation. The lightweight, reinforced cement facing, provides a robust surface that is ideal for direct bonding of tiles. Many other types of finishes such as engineered wood, carpet, vinyl etc can also be used if they are covered with a flexible latex self levelling compound.The panels are ideal for fitting onto solid floors i.e. concrete or screed and also suspended timber floors that have been boarded with suitable floor boarding. The panels are easy to cut and install, and should be laid with the panel joints staggered in a brick bond style. The routed channels are compatible with most flexible low-pressure underfloor heating pipes. The panels are designed for use over existing floors providing a low height build up, insulated floor.The panels are available for use with 12mm pipes with centres at 150mm. At the end of each panel is a series of pre formed return loops and 3 x routed channels which allow flexibility and versatility for multiple heated zones to be fitted.Board Specifications1200mm x 600mm (0.72m²)18mm/2.6kg150mm CentresFor 12mm Pipe0.033W/mKEuroclass E
