Hot floors are proud to offer Rifeng multilayer piping. The multilayer pipe is a five-layer composite pex-al-pex pipe that combines the advantages of copper and plastic and eliminates their disadvantages.

The aluminium core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating through the surface. It compensates and reduces snap-back forces and heat expansion with changes of temperature.

The pipe offers the latest in innovation and technology, providing a working life of over 50 years, a working temperature range from -45 to +95 degrees centigrade and a minimum burst pressure range from 7.0 MPa to 3.5 MPa (1 MPa=145psi=10bar). Also with a 100% diffusion barrier it helps eliminate corrosion and the build-up of micro-organisms in the pipe and fittings. The pex-al-pex multilayer pipe system has been awarded certifications throughout the globe including WRAS certification here in the UK. This means that as well as central heating and underfloor heating applications it can also be used in potable (drinking) water applications. As an underfloor heating pipe, it offers a time and cost saving solution with its ease of installation.
