Conservatory wood frame split

[DIYspanner]

Its a brick base with wood window frame and roof frame.

The columns in to photo have split apart, presumably from the heat and the roof beams pushing on them.

I'm looking at new poly-carbonate sheets for the roof but will need to remove the glazing to repair the columns.

Is it worth putting a skylight in one of the roof panels to vent the hot air?
It gets damn warm when the Sun's on it.

The columns I would guess are half frame jambs -ie the jambs on each frame are machined with an angle on them so when butted together they form the angle of the conservatory.

Maybe those joints are opening up.

I would check to see if the roof has pushed the frames out -where you see a crack, check to see if the frame is vertical.

If its not you need a tie bar fixed across the hips

I fitted a roof vent to my lean to conservatory - well worth it.
I did it when I reroofed.
Previously I added three solar powered extract fans but they died after a few years

I used DIY plastics (in Oxford I think?)

Put a lightweight roof on it - we have a very similar wood framed conservatory and are looking into doing just that. Should sort the heat issues.

I can't see how the rafters (potentially pushing outwards) can spilt frames (sideways) - and frames that are screwed together at that.

The weight of the rafter beams is causing the pushing.

The only support they have at the apex is the mutual pushing on the center beam that's 90 degrees to the house wall.

Basically, due to their own weight, they push out on the window frames.

I need to pull the capping strips of the window frame column to see what the joints are.

I thought a tie bar was necessary in conservatories to stop the roof from spreading ?

Does anyone know what the best colour of polycarb sheet is for deflecting sunlight heat?

I going to fit a coup of opening vents when I put the new roof sheets on. Probably 25mm sheets.

To repair the split window frame columns, I'll lift the center beam of the roof apex with a jack and post which take the weight and help pull the window frame back in.

Presently sourcing roof materials.

I fitted a smooth brown roof to mine.

Yep my last one had exactly that.

Having a conservatory is one of those things, a bit like laying blocks in a trench below dpc... you need to do it once in your life to realise how much you never want to do it again.

Nose you can't put that brown stuff on your conny silly boy

You can if you get rid of that rubbishy plastic stuff between the roof and the masonry.

True but I bet it goes by a posher name now tho!

I've found Opal HeatGuard sheets for the job.

The roof structure wouldn't support slate or tiles.
