Hi All,
I know the topic of insulating a garage has been covered many times but I can't find the answer I am looking for so here goes.
I have a garage with a room above. The garage ceiling is boarded in fire retardant sheet to provide protection to the room above. Unfortunately the void between the ceiling and the room above is not insulated.
I know that I could take up all of the carpet and T&G chipboard above, stuff it with the itchy stuff and then replace everything but that would actually be quite a bit of disturbance. From a building regs, safety or general practically point of view, is there any reason I couldn't overboard the garage ceiling with celotex or similar, leaving the fire proof board in situ thus maintaining fire protection for the room above. I would probably stick the PIR up temporarily with spray adhesive and then mechanically fix through the PIR, through the fireboard and into the ceiling joists. Tape and seal seems between boards.
Thanks in advance.
