I have recently purchased some custom fit wooden blinds to fit to a square (or box) bay window. I followed the measuring guide diligently, and now the blinds have arrived it is time to fit them. What the measuring guide and fitting guide neglected to mention is what to mount the fitting brackets to. This is also something I should have thought about before purchasing them.
The blinds are to be fitted in the following arrangement:
The question is: What do I mount them to?
The ceiling of the bay is (I'm 95% sure) plasterboard. The largest of the three blinds is pretty heavy. I'm not convinced that the plaster board will support the weight of the blind even with a heavy duty plasterboard fixing.
Another option I've read about, is screwing a batten to the joists and mounting the blind to that. I believe the joists run towards the back blind. This shouldn't be a problem for the back blind, but might be a problem when mounting the side blinds as I'm not sure if there'll be anything to screw the batten to.
Mounting the blinds to the window frames is not an option as the windows have protruding handles.
I can't be the only person to have this problem, but there's a surprising lack of information on the internet.
Any help or guidance would be extremely appreciated.
