Are your skylights clouding?
Even though VELUX skylight and roof window panes are of a very high quality, an original VELUX pane will still puncture in time. The service life of a pane varies much depending on a number of influential physical factors, but on average the life of a pane is estimated to about 15 years. If the pane is punctured, it should always be replaced. When a pane is punctured, the level of insulation is considerably lower than with a new, low-energy pane.
Keeping the warmth inside
This results in increased heat loss through the pane, which will partly result in higher heating costs and also in you experiencing a sensation of draught from the skylight or window in the form of down-draught from the pane. It is relatively easy to ascertain if a pane is punctured. If the pane seems dim and you can see unmistakable humidity between the layers of glass, then the pane is punctured. On a roof window, try turning the sash around to the cleaning position - you will often be able to see water drops run between the layers of the glass. This shows that humid atmospheric air has penetrated the space between the panes.
Today, the normal procedure is to replace your punctured insulating glass units by modern low-energy panes. As mentioned, a low-energy pane will result in significantly reduced heating costs and a better indoor climate by keeping the warmth inside a room during the winter and outside during summer.
Contact the VELUX Service Department
to have your punctured skylight or roof window panes replaced with original VELUX panes by a specially-trained VELUX service technician. This is carried out at a fixed price, regardless of where you live in the country. At the same time as the service visit we will provide you with a free check of all your VELUX roof windows.
Alternatively, you can also buy an original VELUX replacement pane at your local timber yard if you want to "do it yourself".
Changing of gaskets at the same time
If your skylight or roof window pane is punctured, your window will normally be about 15 years old. This means it will also be time to change the gaskets. If you want to get the most out of your new low-energy pane, then the gaskets should of course also fit absolutely flush in order to avoid unnecessary heat loss. It would be an advantage to have the gaskets replaced when the service technician visits you anyway. In this way you will avoid having to pay another basic fee.
