Heatflow Underlay

A Unique range of low-tog underlays from Duralay bring a warm glowing feeling to any floor. Duralay Heatflow underlays all have lower 'tog' ratings which allow the warmth generated by underfloor heating to pass quickly into the room. They conduct more heat than other underlays, making them the ideal choice for installations with underfloor heating, bringing greater heating efficiency and the potential of reducing heating bills.

Using the new Thermylin process developed by Interfloor, a combination of additives and manufacturing technique allow the production of underlays with higher thermal conductivity and hence lower thermal resistance than normal, whilst retaining the essential qualities of underfoot comfort and protection.
