We would only recommend a maximum tog rating of 2 5 for underlay and carpet combined for use with underfloor heating.
Carpet and underlay tog rating.
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 carpet underlay tog rating is determined by the composition density and thickness of carpet underlay.
So in this article we re showing you which are the best underlays for the highest tog on the market today.
If you are looking for an underlay for underfloor heating in combination with a carpet this is quite a specialist requirement.
The tog rating is a measure of heat insulation and the higher the tog rating the better an insulator the underlay should be.
Who thought tog rating would be such a significant factor in making your decision when choosing an underlay.
Underfloor heating requires low tog rated underlay and flooring material to ensure that as much heat as possible makes it into the room above.
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.
We recommend that the combined tog rating of carpet and underlay doesn t exceed 2 5.
So rest assured that carpet can be used over underfloor heating systems and will not impair their performance.
Carpet at 1 70 underlay at 1 40 1 70 1 40 1 0 2 10 tog suitable for floors 2 11 tog and.
The lower the tog rating the better in these scenarios because more heat can rise up through the flooring and into the room.
Although a rating of less than 1 0 is normally sufficient the lower the tog value of the underlay the better.
In fact 90 of our customers buy theirs based on the tog rating alone.
There are many factors that contribute to an individual carpets or underlays tog rating including thickness and construction.
Buying the lowest tog is also an important factor when making your purchase decision.
A higher tog rating on the other hand means greater level of heat insulation which is perfect for use.
Both underlay and carpet carry a tog rating.
We would suggest a target tog should be 0 8 or less.
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.
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.
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.
Extensive research has shown that this calculation gives a more realistic value of the total tog value.
We do however recommend that underlays with tog values of less than 1 3tog are used.
A real thermal insulation figure of 2 5 tog is now considered a realistic maximum limit for carpet and underlay combined.
