I'm thinking of using a Multifoil Insulation in the roof
of a new job, now there seems to be some uncertanty
on this product... anyone have an opinion??
There seems to be a significant amount of controversy regarding these types of product: that in practice they do not live up to the claims of the producers.
I think it might be covered more in depth on the Boards.ie website - either in house building or the eco section.
