The system requires no screed and is designed to be used with Warmup’s 12mm PEX-A pipe, which is inserted into the insulation boards. Warmup 12mm PEX-A pipe is at the heart of our system because it is strong, flexible and kink-resistant and comes with our best warranties and guarantees.

With Total-16’s build-up of only 16mm and the straight insulation boards supplied with integrated aluminium heat diffuser plates for greater radiant heat conductivity, the installation time is significantly reduced. This makes Total-16 ideal for new-build and refurbishment projects where floor height is at a premium and installation speed is of the essence.
