Product and Usage Questions
Product and Usage Answers

What is the life span of a roof window?
A: A roof window, like most other building materials, has a long life. If normal maintenance is undertaken, the life span may be vastly prolonged.

Has the wood received any treatment?
A: The wood has been treated with BASEtreatment, a basic impregnation of the wood in order to minimize the risk of fungus. Furthermore, the wood has been varnished with BaseFinish, a water-based lacquer, which provides for an aesthetical appearance as well as a more fungus-resistant surface.

My roof window faces south and sometimes lets in too much light. What should I do?
A: We recommend that you purchase and install a roller blind, type RHL from VELUX, which is available in more than 75 variants. For more information and an overview of the wide variety of colours and designs available, please visit www.velux.com or contact your point of purchase.

My window is installed too high and I can't operate the window. What should I do?
A: We recommend that you use electrical operators, which are compatible with the your roof window system. These include electrical operating products from WindowMaster such as the WUX 120 and WMG 510, which enable remote control opening of the window. For more information, please visit www.windowmaster.com or contact your point of purchase.

There is condensation on the inside of my pane. What should I do?
A: You should ensure that the room is adequately ventilated. Also, be aware that condensation on the inside of the pane often comes from not having a heat source underneath the window. Furthermore, the interior lining should be horizontal over the window and vertical under the window, thereby ensuring optimum flow of air and maximum light.

Why do the panes of my roof windows fog up on the outside?
A: Fogging occurs when the air outside condenses when the temperature falls.

Will sunlight make my carpet and curtains fade?
A: Due to the low-energy glazing unit of the roof window, fading will be negligible. To avoid too much sunlight, we recommend using a VELUX roller blind, type RHL.
