ability of glass to withstand this wind

40701085

On stormy days like these, I look at the DG window in my bay and can see the glass pane move in & out in a sort of bulging movement with the gusting wind - sometimes by what looks like a lot to me (1/4 inch maybe?).:eek:

Its a big pane, maybe 1.5m square. Is this level of movment normal & ok for glass? Is there a certain size beyond which they shouldn't make single panes of glass for ordinary houses?

Just want to avoid the worst...cheers

I live in an elevated coastal site and this morning we had gusts up to 110km/hr. our sunroom has s south facing wall with eight large DG panes of approx 1.2m X 2m. The glass is just regular 4mm and in these winds it can look scary to see them bulging. We have had them in for a few years now and we are confident they can hold up to the worst storms.I would check the silicone or seals regularly for fatique and replace as necessary.
