How does Invizimelt achieve 100% heat utilization?

Once Tuff Cable is snapped into the Invizimelt panel channels, aluminum tape is applied over the cable and panel surface. Aluminum’s high thermal conductivity means heat from the cable spreads rapidly and evenly across the full panel face, with no heat lost downward into the sub-roof below. The result is that essentially 100% of the electrical energy consumed by the Tuff Cable is converted to useful heat at the panel surface — making Invizimelt one of the most energy-efficient under-roof heating configurations available.
