Due to the technology placed within double-glazed windows, there are a lot more ways of disrepair and dysfunctionality occurring aside from the usual chips and cracks. Here are a couple of ways you can gauge their effectivity – to ensure your Aberdeen windows work at peak performance. One thing to watch out for is condensation. Whilst condensation on the outside surfaces of the window can be hard to avoid, there shouldn’t be any at all between the panes. If you notice that condensation has begun to drip inside the window, then that is a sign that the insulation protection has failed. There are a couple of reasons this could be, but usually, it’s the failure of the seals on the edges of the window. When they fail, moisture can enter the space between the window panes. Another way to tell if your windows need a repair is if you feel a draught. This is a sign of the window’s failure to close properly, or much like the last option, the seal has failed – although to a much larger extent. Identifying the source of the problem should be done through an inspection of both areas.
