Condensation forms naturally yet many homeowners think that these droplets are a sign that something has gone wrong.
In fact, in the majority of cases, the opposite is true – condensation is a sign that everything is working as it should! If moisture is collecting on the outer panes of your window then the units are keeping cold air out and warm air in.
Only if condensation appears between the inner panes of a double- or triple-glazed unit should you be concerned. Please see our ‘guides and advice.’ section for more information.
