Flat Roof Window Condensation

Reducing moisture can be achieved by completing actions such as using extractor fans when cooking drying clothes outside or in a tumble dryer or opening roof windows when possible.

Flat roof window condensation. This means they are cooled considerably more than vertical windows and due to the fact that warm air rises condensation will form on the glass of a roof window before a vertical window in the same environment. Condensation builds when there s an excess of moisture in the air. Over time this excess moisture can lead to the unseen decay in roof timbers and fixings. Condensation and roof windows due to the position of roof windows they are more exposed to the elements.

You may notice condensation on your rooflight window because warm air which holds more moisture tends to rise and then liquefy when it comes into contact with a cool surface. So the best way of preventing condensation is to reduce this amount of moisture. Condensation can cause a number of problems within a building particularly interstitial condensation which can occur inside the roof s structure. Flat roofs and low slope roofs also face potentially serious condensation problems that can in turn lead to costly rot or mold damage in buildings.

Condensation is more prevalent in new homes. When there is a big temperature difference between the outdoors and indoors like during winter this can result in condensation on windows. Condensation is usually more noticeable on roof windows and flat roof windows because warm moist air rises to the ceiling. Interstitial condensation creates structural damping and subsequent damage that occurs when moist air penetrates inside the hidden space within an enclosed wall roof or floor cavity of a home.
