HotMetalPRO4X is a simple patent pending one-piece roof edge ice melt system engineered to install on all new construction or re-roof projects on roof edge below corrugated, pro-panel, and standing seam metal roofs. Specially designed three sided angulated raceways securely hold commercial grade self regulating heat trace cables in place for a direct heat transfer for maximum performance and achieve a minimum 40 inch melt back . The benefit of a direct heat transfer is less heat trace cable is needed to prevent ice dam and icicles formations on roof edges. Less heat trace cable means lower energy costs. In addition, comparative thermal analysis completed by an independent third party helped to determine the optimal distance between heat cables to achieve maximum melting capacity. Easily installs around gutters and downspouts.
