Wall finish in attached garage

[vivienz]

Whilst I wait for a reply from my BCO, does anyone know what building regs require as the finish on the garage wall once the fire rated plasterboard has gone up? The BCO has already confirmed that a single layer of pb is fine, but someone raised a query about whether the inevitable gaps between the boards need to be sealed in some way.

 

We don't want to plaster it, if avoidable, and the BCO was fine with this but he didn't mention anything further about the finish.

I think it’s all about what your BCO will accept, there seems to be no national standard for a lot of building regs stuff.

The joins need to be filled to achieve the fire rating.

I always believe it needed to be 2 sheets of the 15mm fireline plasterboard, with the joints in the second layer staggered from the first layer.  At least that is what I have done.

 

As to finish, taped and filled and then painted.

It’s as Dave says 

Two layers of 15 mil FL

Joints taped and perimeter Gyp sealed

Thanks all. My BCO is generally very relaxed, perhaps a little too much on this occasion. Will get some more PB in!
