greenhouse roof windows slipping

[novicegardener]

hi, wondered if anyone has any tips on stopping my greenhouse roof glass from slipping. - the glass is in individual toughened glass sheets sitting on a rubber strips either side with long plastic clips running the length of each pane. At the bottom of each pane I have been unable to thread a rubber seal to the gutter end as I found it really tricky - I did try to use a a silicon gun instead but it seemed to gum up the guttering and didn't ultimately stop the glass from slipping.

does anyone have any ideas or tips on how I could remedy this situation please.

many thanks

Not sure I fully understand what is happening but I thought these held the glass in place: P.S Welcome to the vine.

Could you maybe post a pic showing the present set up. Very difficult to try to envisage the problem without seeing it

Im sure we will be able to help but i think we're going to need a pic. maybe a pic from a slight distance but also a close up on how your glass is sitting on the frame? .

Good Morning

I've just completed building a greenhouse and used these Z clips with no problems. Easy to install.

many thanks for the feedback - I will have another look and take a pic and post this if necessary - the Z clips may work and will see if this could be suitable also.

I'd contact the supplier and see what suggestions they come up with.

I think the OP is referring to bar capping (as sold by The Greenhouse People, and others, which replace the Z clips.


I have bar capping on my Simplicity Classic 8x6 and the glass does not slip at all. You must make sure that the bar capping is firmly tapped into place; this takes more effort than you would think.

Simplicity also beds the glass onto a foam strip which is double sided sticky - this may be missing/deteriorated in the OP's greenhouse - the OP will be able to confirm this by seeing if the glass is bedded on the foam and if the bar capping is loose when properly clipped in.
