Thanks to the intermediate layer of aluminum, the pipes are diffusion-tight. They are also straight and stiff, almost like a metal pipe, although they weigh much less and are thus easier to handle. They are perfect for visible installations and vertical or horizontal main risers. The pipes are available in dimensions 16-75 mm in straight lengths and in coils up to dimension 40 mm.
