 SP+ five layer pipes are a combination of aluminum and polymer, the product integrates the positive advantages of both plastic and metal , while eliminates their disadvantages. five layer pipe is basically made of a layer of aluminum, sandwiched between  two layers of Pex/Pert. two adhesive layers join the metal part to the internal and external plastic pipe. The metal layer which is overlap welded along the length of pipe, serves as an oxygen barrier, stopping the oxygen diffusion through the polymer  matrix. It also compensates and reduces snap-back forces and heat expansion with changes of temperature.
our five layer pipes are unrivalled in their suitability for under floor heating systems and due to their high specification are equally suited to drinking water installations. We also offer PE/AL/PE pipes for cold water supply.
