What thickness of Thermafleece should I use?
This will depend on where the insulation is to be fitted and the desired U value that you need to achieve for the property. If you are upgrading your loft, basically the more insulation you can put in the better, but whatever you can put in will help significantly – as a guide a 250 mm thickness will achieve current Building Regulations. For further advice and to calculate U values, please ring our Technical Help Line on 0844 800 9953.
