Tog Rating Of Engineered Flooring

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.

Tog rating of engineered 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. 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. If underfloor heating is being used then the underlay should be suitable for use with the underfloor heating product and therefore have a low tog rating such as 0 35 tog. When choosing a wood floor to pair with underfloor heating consider its tog rating.

This is a measurement of the thermal resistance in the floor. Therefore in the case of a flooring underlay the tog rating refers to the difference in temperature between the top and bottom layers. Upwards of 2 20 per square foot for engineered hardwood compared to upwards of 3 40 per square foot for solid. Anything under 1 5 will allow a great heat output.

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. When it comes to wood flooring underlay again you should be looking for an underlay with a tog rating of 0 5 or lower to make sure that the heat can pass successfully.
