We only use high quality European standard Pert-Al-Pert pipe in all our water underfloor heating systems.



Our range of pert-al-pert pipe is manufactured to ISO9001 European standards ensuring a lifetime of outstanding performance & reliability.

Five layer 16mm pert-al-pert pipe is used in all of our warm water underfloor heating kits and offers unrivaled suitability for underfloor heating by combining the best elements of a plastic and metal pipe into one product.

The aluminium core provides strength and importantly acts as an oxygen barrier to stop the ingress of oxygen into the system causing premature wear (corrosion) to the manifold. The aluminium layer also makes the pipe form-stable, making it very easy to work with by eliminating spring back for easier installation.
