Tog Rating Of Engineered Flooring

A lower tog rating allows the warmth generated by underfloor heating to efficiently pass through the duralay heatflow underlay evenly distributing across the floor and into the room saving energy and reducing heating bills.

Tog rating of engineered flooring.

Most wood flooring underlays are marked with their tog rating and also a clear indication as to whether they are suitable for use with under floor heating or not. Better still it s competitively priced compared to solid hardwood flooring. If you ve already started reviewing your options in the hardwood flooring market then you ll be well aware that engineered hardwood flooring is an increasingly popular product. And the good news is all our engineered floors are rated between 1 and 1 2 meaning they re well within the recommended range.

In more technical terms a tog equates to ten times the temperature difference measured in c between two surfaces of a given material when the flow of heat is equal to one watt per square meter. This is because the heat needs to be transferred from the underfloor heating system to the chosen floor covering so the least thermal resistance is needed. Therefore in the case of a flooring underlay the tog rating refers to the difference in temperature between the top and bottom layers. This is a measurement of the thermal resistance in the floor.

When choosing a wood floor to pair with underfloor heating consider its tog rating. Upwards of 2 20 per square foot for engineered hardwood compared to upwards of 3 40 per square foot for solid.
