A specialized underlay with low thermal resistance that gives a warm feel to any floor. Duralay Heatflow underlays have a lower thermal resistance, allowing heat generated by underfloor heating to enter the room quickly. They conduct more heat than other underlays, making them an ideal choice for underfloor heating installations, providing greater heating capacity and a lower energy consumption. Interfloor's unique production techniques enable them to produce underlays with higher thermal conductivity and thus lower thermal resistance than usual, while maintaining essential qualities of floor comfort and protection. The low thermal resistance makes it perfect for wood and laminate floors in conjunction with underfloor heating. Sponge rubber underlay for excellent floor comfort. Extends the lifespan of the carpet.
