greenhouse glass

Hi, i do not understand when going to my allotment this morning, after the bad winds, i found YET AGAIN my glass out the top left side, ALL 4 panes out, ( i mean the back left as standing at the doors.. ) 2 smashed, This happened about 4 weeks ago too, after slight winds...!

 

Hi Sleppy, If the glass is sitting squarely then I suggest you silicone it to the frame to stop it lifting,I assume it is an aluminium frame,and make sure the frame is secure. You haven't upset the chap in the next allotment have you? :D

 

Hi Sleppy. Welcome to the forum, I lost 3 panes in the recent winds. It's to do with wind pressure and the amazing thing is the glass is 'sucked' out not blown in. I'm afraid it's just one of the prices we have to pay for living in the UK. You could buy toughened glass which lasts a bit better but is far more expensive.

 

Hi ya John, thanks for your reply, yes i was standing at the rear of the GH when the winds was up again today, AND there it was, bellowing out, but why.. the doors are closed, my leaves are'nt moving at all on my strawberries..!! windows closed, and yes... Toughened glass too..
< ((

 

..... IS THERE NO WAY TO STRENGTEN THE REAR OF MY GH.. ? Thanks.. Paul.

 

Hi NICK, hahahaha, thanks for your reply, I DONT THINK I UPSET ANYBODY..! thats what i thought before, A LITTLE WORRYING TOO.. ! you say silicone to stop my WHOLE frame lifting you mean.. ?

 

No Sleppy,only the glass in the frame,you will need to fix the frame down with spikes or drill and screw to whatever the frame is based on.. Earlier wooden putty faced glazed frames didn't have this problem..even with thinner glass. I have worked on very old timber G-houses and never seen this problem. Silicone to glass in aluminium allows movement to compensate the extra 'twist' of the frame.Laminated glass is slightly more expensive thatntoughened but is also more flexible...and safer as it does not shatter.

 

Pal, not doubting your advice but wouldnt the glazing tape be a better bet than silicone. If the glass breaks its a pregnant dog to clean silicone off.
