Double Glazed Windows
11 Answers
The double glazed units on my bedroom windows have failed allowing condensation to build up inside the glass unit, I have been told that as temporary measure you can drill a small hole in the inside piece of glass and this will help to ease the problem. Can anyone tell me if this works

For more on marking an answer as the "Best Answer", please visit our FAQ.I think you'll find they are filled with dry nitrogen, you couldn't have a vacuum, a vacuum would exert approx' 14 lbs per sq ins on the glass, just under a ton per sq ft, so a window say 4ft X 3ft would have about 10 ton pressing on it, regards the hole, I think you'll struggle to drill one in the glass ( it might even be toughened ) and if you took the unit out and drilled one through the metal / rubber seal, would you be able to get the condensation out?

As Whickerman says, there is is a ref' in wikipedia to vacuum units, but the fact is that under vacuum conditions the 2 sheets of glass would touch each other in the middle in a domestic size window, if they hadn't broken, I checked with a local double glazing manufacturer ( not installer ) who tells me that his and most other units are just filled with air and silica gel to remove the condensation.
I've heard of that suggestion as regards plastic double glazed windows in touring caravans, where sometimes there's a small plug in a bottom corner that can be removed to allow condensation to escape. Never heard of anything similar for domestic glass and I certainly wouldn't recommend it. I think you'll be looking at a replacement unit to solve your problem.
