Enlarging a loft opening

Postby Lawrence » Thu Jul 19, 2007 9:45 am

I want to increase a loft opening to approx. 1000mm x 700mm.
This will invlove cutting across anther joist

Are there any regs I need to follow in constructing a trap door e.g. can it be made out of 18mm plywood or dioes it need to be specially treated fire retardant material? Does it need insulation as well?
