What is a good tog rating for a carpet.

A tog rating indicates the effectiveness of a materials heat insulation. We recommend that the combined tog rating of carpet and underlay doesn t exceed 2 5. A low rating is perfect for use with under floor heating while a high rating means the carpet and underlay already offer good insulation and therefore isn t suitable for under floor heating. A tog rating is a measure of heat insulation and when it comes to flooring it s a great indicator of which underlay is good for use with underfloor heating.

If using underlay with underfloor heating you won t need anything above a total rating of 2 5 tog. 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 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. A tog is the unit of measurement we use to show a material s or carpet s thermal insulating property.

Both the carpet and the underlay will have a separate tog rating and a combined rating over 2 0 isn t really suitable for underfloor heating. Therefore in the case of a flooring underlay the tog rating refers to the difference in temperature between the top and bottom layers.

To determine a working approximation the tog rating of both carpet and underlay should be added together and 1 0 tog subtracted.

Extensive research has shown that this calculation gives a more realistic value of the total tog value. In short form the higher the tog value material or carpet has the more it will retain heat and the better it will be at insulating.

Underlays come with a tog rating the higher the tog the better the insulation. What is carpet tog. Carpets with a lower tog rating are ideal for rooms with underfloor heating whereas higher tog ratings are better for typically colder areas. 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.
