Logix Insulated Concrete Forms Ltd. is pleased to announce the launch of Heat-Sheet a new lightweight radiant floor insulating system designed for slab-on-grade, sandwich slab, snow-melt, retrofit and overlay applications. Compact 2 x 4 ft Heat-Sheet panels are made with Type 2 or Type 3 EPS, come in six thicknesses and offer R-values from R4 to R14. Heat-Sheet's tough preformed nodules resist jobsite breakage and form the convenient 3 in multi-directional tubing channel grid. With Heat-Sheet, 1/2, 5/8 or 3/4 in radiant floor tubing easily walks into place and stays in place without ties, clips or staples in most cases.
