greenhouse damage!

[chilli_grower]

Hi VC, laminated glass is literally 2 panes of glass stuck together with a piece of laminate sandwiched in the centre, to stop it smashing everywhere.

Toughened is the stuff that crumbles into tiny pieces when smashed (like a car windscreen).

Yes g/h glass is 4mm, but 6mm will fit, it just means that the glass will sit a little 'proud'.

At least I hope it will fit!

6mm is the smallest laminate available.

If the laminate is no good, then I will have to just stick with polycarb.....

I agree that "thicker" will fit, and the W-clips are springy, so I assume they will hold it in place.

What about the Z-clips that hold each overlapping pane though? (Some greenhouses have a single floor-to-gutter and, presumably, gutter-to-ridge pane. Heavy to put into place though ...)

Hi Kristen,


Yes I am basing my theory largely on the fact that the clips are springy. And as the glass is 6mm and not 4mm, it should infact apply more pressure to the pane.

Someone else mentioned that I could have used 2 x square panes along with z clips. And yes that is a good idea. I might well end up doing that.

But for now I have one piece arriving.

My existing polycarb panes are one piece floor to gutter, andone piece gutter to apex.

THe other minor issue is that the existing 4mm polycarb fits into a slot/groove along the roof line. This of course will not be possible with thicker glass. So I will just butt the glass up and silicone it in.

I dont foresee any problems!!!!!!! Yet....

Could you swap one of the side polycarb panels into the roof and use the laminated stuff on the side?

[chilli_grower]

now that is a very good idea!!!!

If necessary I will do exactly that!

I am pretty sure they are the same size

Good thinking!

[Kristen]

Are the sides silicon'd in? IF so I think they may be hard to get back out again.

[chilli_grower]

nope. I only siliconed over the clips.

I can flip them out easy with a screwdriver.

Photos to follow on the weekend, when I can actually see what I am doing.

I leave my house at dark, and get home at dark, so I cant see a thing!

Really annoys me having to eat into my weekend for this sort of thing.....

[chilli_grower]

all sorted.

I ended up using polycarb (long story).

However, you can see that I put a baton strut across the inside of the roof panes first.

When it dries up a bit, I will then silicone over the clips...

The new pane sure lets through a lot more light than the old ones!

Happy now
