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.

Tog rating of engineered flooring.

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. 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. Better still it s competitively priced compared to solid hardwood flooring.

Anything under 1 5 will allow a great heat output. 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. When choosing a wood floor to pair with underfloor heating consider its tog rating. 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.

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. Upwards of 2 20 per square foot for engineered hardwood compared to upwards of 3 40 per square foot for solid.
