Leaking double glazing

Postby philbasford » Sat Dec 13, 2008 4:42 pm

one of my window leaks when it rains, its double glazed, a small damp patch appears at the bottom corner(but only one corner of the window), i thought i had solved the problem, but it seems to be backed, an just wondering what the next step might be.

Ie replaced the sealent, but today the patch of damp was 3 times the size of what it used to be and am now getting rather concerned

Any help would be appreciated!


It only gets damp on the inside when the rain is heavy for a decent period of time.

I assume you are saying that the water is coming in around the glass unit.
How are the DGUs sealed into their frames? eg is it a bead of putty, is there a full bead of bevelled putty around the window, is the DGU set in a rubber seal, what sort of frames are they?
