Wool carpets have a higher tog rating naturally than other fibers as do foam underlays over felts.
High tog rating carpet.
If using underlay with underfloor heating you won t need anything above a total rating of 2 5 tog.
Other considerations such as to the weight of the carpet should also be considered when buying.
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.
Underlays come with a tog rating the higher the tog the better the insulation.
Both underlay and carpet carry a tog rating.
Put simply the higher the tog rating the greater the insulation.
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.
Carpets with a lower tog rating are ideal for rooms with underfloor heating whereas higher tog ratings are better for typically colder areas.
A tog rating indicates the effectiveness of a materials heat insulation.
Every home is different so ask our experts in store to help you understand exactly what it is you need.
A material with a high tog value would make an excellent winter coat as it would retain a large proportion of your body s heat while wearing it while a coat manufactured from a low tog rated material would be better suited for use in warmer seasons as it would allow a far greater amount of your body s heat to radiate away while being worn.
