VELUX recommend that you lubricate fittings and hinges at least once a year. This includes the pivot hinge and lock. Simply apply the lubricant to the areas and close the window.
For electric windows, it is recommended that the gas springs and motors are replaced within 10 years after installation of the window as their performance is likely to decline slightly over the years.
If you live in an area that is susceptible to prolonged cold periods with heavy snowfall you must ensure that you have an adequate drainage system to cope with excess water. When the temperature begins to rise, your windows will often be one of the first places where the snow and ice will start to melt. Don’t forget to clean the flashing around your windows. Leaves and other debris should be removed from the flashing once per year to allow excess rainwater to flow freely.
When you start to notice that condensation is forming on the glazing of your windows, this may be a warning sign that you should ventilate more often. Regular ventilation is the most efficient way of preventing condensation from forming on your window glazing. To limit the amount of humidity in your house be sure to ventilate regularly by opening your VELUX windows for five minutes, preferably daily.
