Here you will find all our wood flooring underlays that have a low TOG rating, and are suitable for use with warm water underfloor heating systems. All of these underlays are non-insulating and have a TOG rating of less than 1 (R Value of less than 0.1), however for best practice and to improve efficiency we recommend wood flooring underlay with a TOG rating of less than 0.5 (R Value of less than 0.05) Our premium products with a TOG of less than 0.5 are also included below.
VERY IMPORTANT NOTE:
Please assess the TOG rating on each product. For Underfloor heating, lower TOG values provide better performance (although other considerations may be appropriate also)
