I am building a 4metre deep single storey rear extension, it will have a pitched roof at about 13 degrees. I want a flat ceiling but I'm guessing that 4x2's will be too weak to span that distance without sagging?
The binder doesn't have to be 8m long - do it in two or three pieces.Thanks Wood. The room will be 4m out by 8m wide, I presume I can't use binders cos at 8m wide I can't get a single timber binder long enough to sit on the walls at each end, or can I bolt a couple of 5m binders together to give me the 8m span? if so, what size would the binders have to be?
