Was going to fix battens using self tapping screws into the aluminium. As long as it's in the centre, should be ok, seen others do this.Doubt you could fix to them without shattering glass , very little space or depth for fixing .
Good point. What do you think?I think the question you've not asked is would they be strong enough to take plasterboard and snow?
Yes. There will be new lighting and our kitchen will be opened into the space.Is that a picture of your conservatory? A lot to consider there, Your house becoming very dark for one!
It was already there when we moved in. It's around 10 years old.Did you have that conservatory built? it doesn't look that old.
The bars flex a bit (more than l thought) l noticed when cleaning, which worried me adding the extra weight of plasterboard, being glazed too, would it collapse. Plus the natural movement may crack the plaster.9.5mm plasterboard and skim weighs nothing. uPVC cladding even less. Is there a reason for the boarding? Generally it's heat loss/gain and involves insulation. Have you considered retaining a bit of the glazing (using a bit of uPVC trim to form a frame) as "skylights" to provide a bit of natural light?
I'm probably going to build a timber frame underneath, independent of the bars so l don't put any extra stress on the existing structure. I'll still batten and superquilt first, then celotex between my new joists so l have the best of both then.I have seen people using pvc hollow soffit cladding for the inside instead of plasterboard which would be lighter and more flexible.
I personally wouldn't go down any route involving keeping the old bars and glazing, I would build a new timber roof and insulate it with the usual celotex/kingspan and then probably use rubber for ease and weight, and if you want to save some of the glass you could use those as skylights.
