How to prevent condensation on uPVC Windows

Causes of Condensation

Condensation is moisture in the air turned into water. The warmer the air is, the more moisture it can hold, when its limit is reached and the warm air makes contact with a cold, non-absorbant surface, it becomes chilled and sheds the excess moisture in water droplets, usually seen on glass surfaces.

Living Room Condensation

Allow the rooms warmth to reach windows by positioning the curtains slightly away from the windows.

Kitchen Window Condensation

• Close doorways into the remainder of the house and keep a window open.
• Extractor fans can help.

Bedroom Condensation

The prime cause for condenstaion in bedrooms is not allowing for the night time drop in outside temperatures.

• Extend the central heating programme or other heating system accordingly.
• Ventilate by opening the windows at least once a day to allow air-exchanges.

Bathroom Window Condensation

• To stop moisture from travelling around the house, keep the door closed during and after bathing.
• Whilst bathing it is advisable to open windows slightly to aid ventilation.

Outdoor Condensation

Condensation forms on the outdoor surface of glass when its temperature drops below the outdoor dew point temperature.

Evolution windows are manufactered using thermally efficient glass. The glass keeps heat inside the rooms of your house and reflects heat from radiators and fires back into the room.

As a result, the outer pane of glass does not get warmed by heat escaping from inside the building through the glass and remains cooler in comparison to much less thermally efficient windows.

It is possible that external condensation will appear on the same windows but not on others, due to the position of windows in the house.

If condensation appears externally on your windows, this is in no way a defect of the unit. It must be seen as a positive indication that your windows are thermally efficient and are reducing heat loss.

*We cannot guarantee against the incidence of condensation.
