Johanna Constantinou, Interior Trends Expert at Tapi said your choice of flooring could help keep energy bills down long-term, as up to 20% of heat loss in the home occurs through the floor. ‌Jo said: “The best type of flooring to reduce energy costs is carpet, as carpet fibres trap cold air, reducing draught and acting as a natural insulator. The denser the pile of your carpet, the greater the thermal insulation, leading to reduced heating bills. So, carpet, and especially wool carpet, is worth considering for long-term financial savings. At Tapi, we use a 'TOG Rating' where 1 TOG = 0.1 R-value.”As well as considering your visible flooring, you should also look at carpet underlay too.
