Hi All
I have just had a detached garage built with a room above and need t fireproof the garage ceiling and stairs. I was told by the building inspector to use two layers of plasterboard, but will one layer o Fireline plasterboard do the same job?
I also want to fit cavity insulation, what types can be used now tha the walls are up and roof on. If I use one of the blown-in types, ho do I seal the cavity tops bearing in mind that the inner block leaf i around two courses higher than the outer brick leaf?
Cheers
Garet
