Our Profix overlay panels are available in two options: the 15mm Profix panel, a low-profile rigid plastic system ideal for retrofits and keeping floor build-up to a minimum, and the 20mm Profix™ PLUS panel, a self-adhesive board with enhanced pipe retention and higher heat output, perfect for both suspended and solid floors. Both options provide a fast-fit, efficient solution for warm water underfloor heating using 14–17mm pipe.
