This product is suitable for Underfloor Heating.

Duralay Heatflow underlay uses the Duralay's Thermylin™ process. It is specifically designed for use with normally operated underfloor heating systems (those that produce floor surface temperatures of not more than 29 degrees centigrade for central areas and 35 degrees centigrade for peripheral areas)

Heatflow underlay conducts more heat than other underlays, making it an ideal choice for installations with underfloor heating , with a low tog rating of 0.33. Prevents overstraining of joints in wood and laminate board. Creates a receptive surface, helping mask slight unevenness and minor blemishes found in the screed surface. High density resilient rubber underlay laid under wood and laminate flooring will keep noise to a minimum, making your environment a much more peaceful place to be.
