What can affect the performance of a window?
The following may cause condensation to form on a window: Air Circulation – a window may be in an area in which there is poor circulation of warm air. This means that the temperature of the inside glass surface is colder than in other parts of the home and this may cause condensation to form at humidity levels which are practical for the rest of the home. Drapes – By drawing heavy drapes over a window, or patio door, the possibility of condensation can be increased because the flow of warm air is restricted. Interior insulating devices – insulating blinds, shutters, or similar devices, applied to the interior of windows, can contribute to condensation problems when moist indoor air is trapped between the device and the window. The insulating properties of these devices cause the temperature of the glass surface to be lower than normal and the trapped air to condense into moisture. Varying Humidity Levels – remember that the humidity in some rooms, kitchens and bathrooms in particular,
