Are you in the throws of new-build design? Or do you intend to convert your loft into a living attic? If so, you can take measures beforehand that will pay off in the end. Please note the following: THE RADIATOR When deciding on the position of your radiators, make sure that all radiators are placed beneath a window. That includes roof windows. In order to efficiently prevent condensation it is important that heated air can circulate freely and warm up the pane. Therefore, make sure to also install a lining and an air-diverting windowsill. VELUX LINING Due to its special construction, VELUX linings circulate the heated air from the radiator freely across the pane. Furthermore, a special VELUX window sill optimises this circulation even more. If you combine both the lining and the window sill, you reduce the possibilities of condensation forming on your roof windows.
