The PE-RT-AL-PE-RT heating pipe is a very strong PE-RT pipe with a thin aluminium layer in between. The aluminium layer serves as an oxygen barrier, which stops the diffusion of oxygen through the polymer matrix. This ensures that even at temperatures of above 80 degrees °C, no oxygen dissolves in the water preventing the metal components of the system to corrode. PE-RT-AL-PE-RT pipes combine the advantages of copper and plastic, but have none of their disadvantages.

Construction of the PE-RT Alu PE-RT heating pipe

a. PE-RT inner layer
b. Adhesive layer
c. Aluminium layer
d. Adhesive layer
e. PE-RT outer layer
