Condensation is the moisture that sometimes appears on the inside or outside of a glass surface on doors and windows, and it can be really annoying – especially when blocking the amazing view of your sleek bifolding doors.
Here at UK-Bifolds we’ve been asked this question before: Why do my doors and windows have condensation? Is this a problem?
The answer is simple – no, this isn’t a problem and here is why.
Exterior Condensation
Condensation on the outside of your doors or windows is a completely natural phenomenon; when humidity is high it creates condensation on any surface of a temperature lower than that of the air touching it. Therefore, this is bound to happen especially during autumn and spring, when the air is cooler in the morning or night but then it warms up when the sun comes out at midday.
While this occurrence might be annoying, it really isn’t anything to worry about. In fact, it is something that affects properties with very efficient double-glazed or triple-glazed doors and windows, and it simply means that the glazing is so efficient that the outer pane is much colder than the inner one, resulting in the condensing reaction with the air outside!
