How do I reduce mould on my windows?
Mould growth is common whenever an organic food source (something derived from a plant or animal, such as paper, wood, and cardboard) comes in contact with moisture for any extended period of time.
This means the timber reveal around aluminium windows or the actual frame on timber windows is prone to mould growth especially in the colder months of the year.
It’s not the cold air that causes the mould but the warm air from heating your home. When warm, moist air is cooled, condensation occurs which in turn causes mould growth.
