Winter is fast approaching in the UK and temperatures dropping each day. Many of us will be waking up each morning to see condensation on the windows.
This happens when the moist air comes into contact with the cold surface of the windows. As winter draws in, it's likely that we won't be opening windows as frequently.
Lack of ventilation is a prime condition for condensation. It also causes damp and mould to thrive on windows, sills and frames, which can cause health issues.
