Carpet And Underlay Tog Rating

So we ll also.

Carpet and underlay tog rating.

Buying the lowest tog is also an important factor when making your purchase decision. Underfloor heating requires low tog rated underlay and flooring material to ensure that as much heat as possible makes it into the room above. The carpet underlay tog rating is determined by the composition density and thickness of carpet underlay. Extensive research has shown that this calculation gives a more realistic value of the total tog value.

This is to prevent the underlay carpet molding itself to the levels of the shape of cables in the matting so that they can be seen on the carpet. We recommend that the combined tog rating of carpet and underlay doesn t exceed 2 5. A real thermal insulation figure of 2 5 tog is now considered a realistic maximum limit for carpet and underlay combined. The maximum tog value quoted by the system manufacturer should be adhered to we always recommend that you consult with the heating manufacturer to ensure that the carpet underlay combined tog value.

We do however recommend that underlays with tog values of less than 1 3tog are used. There are many factors that contribute to an individual carpets or underlays tog rating including thickness and construction. Carpet underlay tends vary from 1 0 to 4 0 tog rating. So rest assured that carpet can be used over underfloor heating systems and will not impair their performance.

Although a rating of less than 1 0 is normally sufficient the lower the tog value of the underlay the better. The tog of the carpet tells you how insulated it is generally the lower the tog the less insulation it provides so opt for a low tog carpet if you have underfloor heating. If you are looking for an underlay for underfloor heating in combination with a carpet this is quite a specialist requirement. The lower the tog rating the better in these scenarios because more heat can rise up through the flooring and into the room.

To determine a working approximation the tog rating of both carpet and underlay should be added together and 1 0 tog subtracted. There are two main choices when it comes to tog rating in regards to flooring underlay and material with said choices revolving around budget and whether underfloor heating is present. In fact 90 of our customers buy theirs based on the tog rating alone. Carpet at 1 70 underlay at 1 40 1 70 1 40 1 0 2 10 tog suitable for floors 2 11 tog and.

We would only recommend a maximum tog rating of 2 5 for underlay and carpet combined for use with underfloor heating. A higher tog rating on the other hand means greater level of heat insulation which is perfect for use. We would suggest a target tog should be 0 8 or less. The higher a material s tog rating the more effective it will be at retaining heat and the better it will be as an insulating material.

The tog rating is a measure of heat insulation and the higher the tog rating the better an insulator the underlay should be.
