MultiAI Pipe (PE-RT/AL/PE-RT)

MultiAI Pipe (PE-RT/AL/PE-RT)

Multi-layer pipe for heating systems only, made from a 5-layer composite material using PE-RT as the inner and outer layers coupled with a 0.25mm thick aluminium core. The two further layers are adhesive, to band the aluminium to the inner and outer PE-RT layer. PERT/AL/PE-RT Alpert multilayer can run straight from a distribution point to an outlet point without the need to cut the pipe. This reduces the requirement for joints thus reducing the possibility of leaks.

Multi-layer pipe has no memory so it doesn’t spring or resist when laying and is ideal for single installer.
