6inch gap to plaster around patio door.

[peaps]

9.5mm PB will suffice.

sticking a board beside floating give two dissimliar materials and you are introducing a straight vertical joint that you need to scrim, but which is not present if you float it with solid material.

Definitely! More bother than it's worth,,, i'd bring it out flush with Hardwall/Bonding etc,, anything but plasterboard.

So it's better to introduce plaster that isn't any good with moisture and slap it around a window..?

Thanks to everyone's help, I now have a couple of solutions and will check what will best for me and the gap with the thickness depth double checked.

The room was skimmed, ceiling boarded and skimmed (by a plaster) in Jan but now mother has decided she wanted the patio door replacing before she moved in! She could have told me before

Just as a matter of interest, did the window area come upto the finished plaster? looks like the window was fitted further forward..... Whats above the window?

doesn't retain moisture in the way bonding and the like does from condensation. Or you could just get some 9.5 moisture board....
