Hi guys
Just a quick question.
I need to insulate my porch (which is of a single skin block construction)and I have a few sheets of 50mm kingspan & foilbacked plasterboard which I intend using.
My question is does there have to be an airgap between the external wall & the kingspan, or can I have the kingspan touching the wall on one side & the plasterboard on the oposite side.
It is quite a narrow porch so cant afford to loose to much floor space by making the walls thicker.
Cheers Jim
