Warmup AL-PE-RT pipe


The PE-RT/AL/PE-RT pipe is a 5 layer composite pipe, incorporating layers of PE-RT and adhesives, encasing an aluminium core.

Key benefits


Oxygen barrier

The aluminium core prevents oxygen entering the system via the pipework.


Easy to lay

AL/PE-RT can hold and maintain its shape, when formed by hand.


Corrosion free

The coatings stop oxygen from entering via the pipework minimising the risk of corrosion to the system.

Aluminium Core

The aluminium core acts as the oxygen barrier, preventing corrosion within the system from oxygen that would otherwise enter via the pipework. The aluminium core also allows the pipe to be positioned and shaped by hand, to maintain this shape.

This means that the pipe requires less overall securing to the subfloor or insulation and is less prone to sagging where it is unsecured.
