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.
Please assess the TOG rating on each product. For Underfloor heating, lower TOG values provide better performance (although other considerations may be appropriate also)
