The Advanced Radiant Floor Panel System

Heat-Sheet is a unique insulation panel designed especially for hydronic heating applications. Its primary functions are to conserve energy and reduce cost and labour. Heat-Sheet provides an efficient thermal barrier between the heated slab and the underlying ground. Heat-Sheet permits fast and accurate room temperature response to temperature controllers.

Heat-Sheet panels are made with high-density expanded polystyrene (EPS) designed to support the weight of cast-in-place concrete, and more importantly foot traffic during the installation of tubing and rebar placement. The nodules placed 3” on-center create channels that accommodates multi-direction placement of 1/2″, 5/8”, and nodules placed 4” on-center for 3/4″ I.D. tubing.

Heat-Sheet is manufactured in a 2ft x 4ft panel with interlocking edges to ensure a stable fit between panel joints. Panels are available in a variety of thicknesses to achieve R-Values ranging from R4 to R16.1.

Heat-Sheet will reduce project costs and speed installation because the usual method for positioning tube by tying it down to wire mesh has been replaced. The tube is simply ‘stepped’ into the Heat-Sheet panels, saving a great deal of back-breaking labour. The cost to purchase and install wire mesh may also be eliminated.
