Multi-foils have been caught out in recent years lying through their
teeth about the performance of their materials....Real world
testing has been done proving that anything more than 1.7mēK/W is
bull****.
So no better than a rather thin sheet of Celotex?
Equivalent to a 40mm sheet, yes. Which means that, when installed
properly with a 25mm airgap either side, it is thicker than PIR
insulation.
Well OK. For this project, (i.e. not a controlled development),
40-50mm Celotex would be fine and it isn't really necessary for there
to be an air gap at the front. Plus I believe that the foam is less
expensive. It is certainly easier to fit and seal.
