Planning and fitting
Divide your required area by 15 and round up to whole rolls. Allow for cutting and fitting waste. Dimensions and weights are nominal.
Your fitter should check the underlay against your carpet backing, subfloor and intended use. For underfloor heating, check the combined carpet and underlay tog with the heating supplier. Laboratory test figures describe the tested product; the complete fitted floor affects performance.
