Profix™ Insulation Panels
Profix™ Insulation Panels are laid over the floor area to be heated, within edge insulation positioned around the perimeter which provides a barrier against heat loss and to allow for expansion. The continuous pipework is laid out in circuits and secured to the Profix™ Panels using specially designed “U” shaped plastic staples secured to the panel by means of a purpose made fixing tool. The screed is then applied to the required depth.
Profix™ Insulation Panels are manufactured with either a Cross-Woven Aluminium Foil (Profix™ E) or a High Density Polyethylene (HDPE) Woven Split Film (Profix™ S) laminated to the upper surface. The panel size is 2400 x 1200mm.
Profix™ E is suitable only for use with sand / cement screeds and is an economy product designed for use in domestic projects. Profix™ S is suitable for both sand / cement screeds and liquid flow screeds and is a premium product suitable for use with all screeded floors incorporating warm water underfloor heating systems.
