Whilst a wool-rich carpet is a great insulator on its own, we do often get asked if a Brintons Carpet can work in conjunction with an underfloor heating system.
The Carpet Foundation carried out some research with the Underfloor Heating Manufacturers Association (UHMA) and proved conclusively that most carpet can be used over underfloor heating without impairing the performance of the system. This showed that a carpet/underlay with a combined thermal resistance of less than 2.5 togs allows underfloor systems to operate efficiently.
Our 80% wool/20% nylon carpets have a tog value somewhere between 1.4 and 2.3. The tog value is displayed on each of our carpet pages and on our tog values page. We always recommend you give the information on the tog values for your choice of underlay/carpet to the heating manufacturer so they can ensure that the heating system can perform properly. Copies of test reports are also available on request.
THINGS TO THINK ABOUT
This information is given as a service to our customers only. Suppliers of the flooring timbers, underlays and adhesives together with the underfloor heating manufacturer should be made aware of the combined tog values of the carpet/underlay so that the correct settings and calculations can be used.
