Our high quality PEX-Al-PEX pipes, or PEX/Aluminium/PEX are unrivalled in their suitability for underfloor heating systems and, due to their high specification, are equally suited to drinking water installations (for which they are WRAS approved and certified). They are made of a layer of aluminium sandwiched between two layers of PEX. The metal layer serves as an oxygen barrier, stopping the oxygen diffusion through the polymer matrix, so it cannot dissolve into the water in the tube and corrode the metal components of the system. It also bends better, because the shape memory of the PEX is offset by the aluminium.
