Product Options

Roll Size

A low-tog underlay, made in the UK by Duralay and specially designed for use with underfloor heating. With a thermal resistance of 0.75 - 0.80 togs and a sound impact reduction value of 31db, this carpet underlay will soften the sound of footsteps and help suppress noise transference.

Suitable for areas throughout the home and for heavy contract use.

Important note:- Due to limited availability of Duralay branded Heatflow, we recently took into stock Tredaire branded 'Defender' which is from the same manufacturer and produced in the same factory and on the same machinery and matches the product description shown below. For a limited time you may receive this product with either branding.
