Yes. Web Dynamics advocates the use of multi-foils with a further layer of insulation. In 2008 the LABC issued a new guidance note over the use of multi-foils and strongly recommending the use of British Board of Agrment certified (BBA) multi-foils and that they should be used as part of an insulation system, and not as a single layer, in order to meet the normal roof U-value requirement of 0.2.
