There is no reason why this should ever cause a problem.
Simply go round the windows and ascertain where the drafts are coming in.
Go to your local builders merchant or B&Q or similar, buy some low expansion polyurethane foam and some poly filler, use the foam for large gaps.
Then go round the frames with a burning candle, watch the flame to see if it moves sideways, where it does there will be another crack fill the cracks with poly filler.
As most double glazing installers are hopeless, then go to the outside and check under the window cills, I would bet that there are large gaps between the walls and the underneath of the plastic window cills.
You will be amazed when you discover how badly fitted double glazing is, on a nation wide basis.
You spend a fortune on expensive windows only to have the job spoilt by a couple of cowboys who cannot be bothered to fit the windows correctly.
Its not only in this country, the USA have the authorities pushing people to install windows correctly and the industry fighting back, not wanting to comply with the rules.
