Anyone changed their conservatory roof from glass to celotex and batons.

@vbgr Yes I did go to the top of the ridge. (I wanted to maintain a high ceiling) I fitted the new roof under the original lead flashing where it joined the house. We fitted new 4x2 wooden joists which supports the weight.
The window frames are steel lined and the original frame top beam stayed in place. The 4x2 timbers created a nice space to fit celotex insulation.
There's several ways that you can achieve a new roof and I guess the first consideration is to ensure the windows can take the weight of a new timber construction. Most modern conservatories are designed to support a ton of snow so that's a start!

 

@vbgr Here is picture from above.
It was a complex shape and that's why we opted to follow the exact model and retain the alloy roof and just add the 4x2 timber joists to give strength. You'll notice I fitted two velux type roof windows to keep things bright and airy ☺

 

I wished I had put at least one velux in as the plants don't grow as well as they used to.

It's in the summer you notice it most as in the winter the sun is coming in at a lower angle.

 

hi There, many thanks for all the input you are giving us. I’ve rung the wonderful company who are getting everything together for us, Southern Timber @ Newton Abbott, and they are trying to find UPVC cladding instead of the plaster board so it will be easier. We have only spent about a thousand up to press so have quite a lee way to go. May have to clad the aluminium roof support with wood as you did JR to give it strength. But have to remember the weight. V

 

I have PVC cladding on the ceiling, I could have had plaster but my thinking was any shrinkage or movement could cause the plaster to crack.
I also wanted it done quick.

 

I don’t know if this is a brilliant thought but, if I’m leaving the glass in and I have rather nice pale green pleated blinds inside, why don’t we just paint the celotex white on the side that is next to the glass and that’s it. Less weight and less work. I can quite understand the dorma window idea, but I’m quite used to having just a thick polystyrene up next to the glass to insulate the conservatory so I’m used to having no windows up there and it was ok with the room next to it having a window, but many thanks for bringing this to my attention.

When I had a polycarbonate roof I put a piece of celotex on the underside and left it in full sun the poly got red hot but you might get away with it with glass.
I tried it out because some companies actually just do that and put the insulation on the inside and then just board it over with pvc cladding.
I guess it works .
Celotex is usually silver with writing all over it, not sure if it would paint well but you can try.

 

OK I’ll keep that in mind. Hopefully, when it comes I will have a brilliant idea. V
