Product Information

Wunda's thermally dynamic 16mm PEXb-AL-HDPE pipe has an aluminium core that produces a higher heat output than ordinary Pex and Polybutylene pipe and is easy to use. We offer some sizes in a flexible PVC. Flexible PVC tubing is suitable for internal rather than external applications. Rigid or flexible PVC tubes?

Very low expansion and contraction, just 5cm in 100 linear metres which is similar to copper (Ordinary plastic pipe has an expansion/contraction rate of approximately 50cm in 100 linear metres) We offer 16mm multiplayer pipe in a range of lengths to suit your needs, and in a Premium Pex-Al-Pex option for maximum efficiency. Plastic pipe and plastic tube are both hollow cylinders, but they are not identical. Basically, pipe uses the inside measurement and tube uses the outside measurement. How do we measure our plastic tubing?

Using Barbed Fittings

The 5 layer 16mm pert-al-pert pipe is used in all of our warm water underfloor heating kits and offers unrivalled suitability for underfloor heating by combining the best elements of a plastic and metal pipe into one product. PEXb-AL-HDPE pipe is stiffer than a PEXb-AL-HDPE pipe and is not suitable for use in Overfloor heating systems that require tight bends and close pipe spacing. WRAS Approved– This pipe has been tested and certified with full UNITED KINGDOM ‘WRAS’ approval – a rigorous testing procedure which certificates only the highest quality products as fit for use in UK domestic water applications. High temperature resistance- a maximum sustained working temp up to 70°c & maximum transient temperature up to 85°c

If you are not sure which type of plastic tubing you need then you are welcome to get in touch to request samples which we will post to you using Royal Mail. Plastic tubing shapes Our range of premium 16mm pert-al-pert pipe is manufactured to ISO9001 European standards ensuring outstanding performance & reliability in all types of warm water underfloor heating systems. For pipes, the inside diameter (ID) is of primary importance as it defines the capacity of the pipe. Whereas, for tubes the outside diameter (OD) is more important. Due to the manufacturing process, it is very difficult to achieve both a precise ID and OD. Due to the natural flow of the raw material either the ID or the OD can be consistent, but not both.

The WRAS approval determines that this product can be used in all UK domestic plumbing applications including drinking water installations – as well as central heating and underfloor heating applications. There is an important but often misunderstood difference between tube and pipe, which we explain in our blog. The main difference is how the profiles are manufactured and measured. EVOH pert pipe can only be used for underfloor heating and without the metal layer is extremely easy to bend making it physically less taxing on larger projects.
