I had an extension added to my through lounge 24 years ago. The french windows were replaced by aluminium framed double glazed patio doors. They are still in good condition, airtight and seals are OK, but the area is very cold in the winter.
I wonder whether the chill in the area is because the frames/glass allows heat to escape quickly. Would it be worth for me to add a secondary glazing (these have aluminium frames) to my existing patio doors or should I replace them with new PVC framed double glazed patio doors? I have to weigh up the costs, the effficiency and the insulating qualities of either. Will be it warmer with secondary glazing which I have had estimates of around £600- £700 or should I spend more and get a good quality PVC patio doors?
In short, which would give me better insulation - new PVC double glazed patio doors or add secondary glazing to my existing doors?
Thank you.
