Double Glazing Draught Detector - bintang

The 12 windows in my house were uPVC double glazed about 25 years ago. The rubber surrounds have maybe lost some of their elasticity as very tiny draughts can now be detected, or maybe they are just cold air falling down the panes. Has any poster found a way to decide? There are 89 panes and thus 356 sides, any of which could be at fault and too many for smoking matches, cigarettes or smouldering string. There is a £45 electronic gimmick but I don't want to spend that much and, in any case, am not sure it will deal with this particular problem. I don't know who made the units and they were fitted by a jobbing builder, now defunct.

Hello bintang the one time we have replaced double glazing was due to condensation between the glass.

If the glass is still ok why not replace the rubber surrounds if that is possible.

We have a similair decision to make with our radiators they are over twenty five years old.The new type of radiators are more efficient and not made of sheet metal like ours.

Twenty five years is a fair time for replacement of double glazing in my opinion we have had ours for ten years.

I think the surrounds can be changed. We can't afford complete new units. Our own radiators are mostly 35 years old, some (from when we moved in) a lot older.

I would change the surrounds of your double glazing.Ours is a brown mastic which is cheap to replace.If your glass and plastic or wood is fine that is the cheapest option.I put a bottle of rust prevention and scale build up in our central heating system every year,if your radiators are 35 years there should be quite a few years left in ours.

If you want an expert opinion why not ask a local double glazing supplier/installer to take a look? Many will give you a free quote, and I'm sure they would be happy to explain the nature of the problem (although it will probably be in the form of "if you buy our windows this won't happen because..." and a little bit of questioning should help tease out your answer). We did this when we were looking into our double glazing and our inspector/estimator helped explain our consdensation problem.
