Water vapour is a product of everyday life, and should be extracted by existing means of ventilation, in order to meet Building Regulation requirements. A free flow of fresh air should also be maintained by means such as window, eaves and wall ventilation.
It is particularly important to ventilate new properties, which have, initially, a high water content as a result of building work (plastering, wallpapering, brickwork and painting).
Depending on its temperature, air can absorb water in the form of water vapour, but levels of absorption decrease at lower temperatures.
Condensation forms wherever warm moist air comes into contact with cold surfaces. Due to their nature and location, roof windows are particularly susceptible to condensation, which, if it occurs, is a sign of excess moisture within the room.
The best way to reduce condensation is to have a fully functioning ventilation system.
Ventilation is the process of extraction and replacement of stale air. In order for the ventilation system to work properly, there must be access for fresh air through windows and air vents. The construction of Fakro window locks enables the window to be closed at three points, providing a gap to increase the level of fresh air entering the room without compromising security.
The top bolt allows the fixing of the window when opened. Vents installed in Fakro windows guarantee a continuous and controlled flow of fresh air even when the window is closed.
Condensation can also be limited by careful use of heaters (directly beneath the window), and by installing lining beneath vertical combination windows. Condensation will be reduced through good air circulation in and around windows. In cases when a window-sill is in place beneath a window, a gap should be kept between the sill and the wall, in order to provide proper air circulation. This gap is particularly important if plants are kept on the window-sill.
