The carpet underlay tog rating is determined by the composition density and thickness of carpet underlay.
Carpet and underlay tog rating.
Underfloor heating requires low tog rated underlay and flooring material to ensure that as much heat as possible makes it into the room above.
Carpet underlay tends vary from 1 0 to 4 0 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.
Both underlay and carpet carry a tog rating.
In fact 90 of our customers buy theirs based on the tog rating alone.
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.
We would suggest a target tog should be 0 8 or less.
So in this article we re showing you which are the best underlays for the highest tog on the market today.
We do however recommend that underlays with tog values of less than 1 3tog are used.
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.
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.
So we ll also.
The tog rating is a measure of heat insulation and the higher the tog rating the better an insulator the underlay should be.
So rest assured that carpet can be used over underfloor heating systems and will not impair their performance.
Extensive research has shown that this calculation gives a more realistic value of the total tog value.
The lower the tog rating the better in these scenarios because more heat can rise up through the flooring and into the room.
Buying the lowest tog is also an important factor when making your purchase decision.
There are many factors that contribute to an individual carpets or underlays tog rating including thickness and construction.
Carpet at 1 70 underlay at 1 40 1 70 1 40 1 0 2 10 tog suitable for floors 2 11 tog and.
Although a rating of less than 1 0 is normally sufficient the lower the tog value of the underlay the better.
If you are looking for an underlay for underfloor heating in combination with a carpet this is quite a specialist requirement.
We would only recommend a maximum tog rating of 2 5 for underlay and carpet combined for use with underfloor heating.
To determine a working approximation the tog rating of both carpet and underlay should be added together and 1 0 tog subtracted.
A real thermal insulation figure of 2 5 tog is now considered a realistic maximum limit for carpet and underlay combined.
We recommend that the combined tog rating of carpet and underlay doesn t exceed 2 5.
