My one storey flat (two bedrooms, bathroom and kitchen/living room) has old metal Crittal windows. The walls are mainly solid concrete. There is a condensing boiler in the kitchen and an extractor fan above the cooker.
In the winter, condensation appears on all the windows and causes black mould to grow. I intend to fit an extractor fan in the bathroom but wondered if anyone can give me information about extractor fans that can be fitted into glass. Are they too old fashioned and not made anymore? I do not want to put electric extractor fans in every room because that would mean drilling into the solid concrete walls.
