The panel uses 12mm pipe, the hollow construction allows Latex screed to flow within forming a solid screed around the pipework in about 24 hours.
An adhesive layer on the underside of the panels ensures panels stay in place while the screed is being poured. The design enables very thin screeds to be poured over the panel to give the lowest possible screed build up with an underfloor heating system of just 20mm.
A Warmis screed system will provide the highest heat output of all systems, furthermore, they are the cheapest to purchase, as in most cases the pipe loops are secured to foil faced insulation and then covered with a 65mm screed, this method effectively turns the building slab into the heat emitter.
