A VELUX window in your home brings in an incredible amount of natural daylight. So it is important to keep it clean and in full working order. This maximises its lifespan and keeps your VELUX window working for as long as possible.

Many VELUX windows come with self-cleaning glazing. This is glass manufactured with an easy-to-clean and self-cleaning coating patented by VELUX. It minimises the amount of cleaning required. Ensuring the VELUX window pane remains bright and clear from a build-up of dirt. Having said that, some VELUX windows do not have self-cleaning glazing. Even those that do may need occasional cleaning.

How to clean a VELUX window

VELUX have designed their windows in a specific way. Ensuring they can all rotate into a 180-degree cleaning position. This allows you to reach the outer pane for cleaning purposes.

To clean the pane of a VELUX window, the first step is to rotate the window 180 degrees. This is the same whether your window is top-hung, centre-pivot or a VELUX INTEGRA window.

After rotating the window, secure it into position. Do this by sliding the bolts at the bottom into the side frame. This ensures the window remains in place. Leaving both hands free for cleaning purposes.

To clean the pane of your VELUX window, VELUX recommends using one of the following products:

  • Clean, lint-free cloth.
  • Non-abrasive sponge.
  • Non-metal squeegee designed for windows.

Clean water is usually the best cleaning substance for your VELUX window. For more stubborn stains, you can use non-abrasive household cleaners. If you live in an area with hard water, add a small amount of detergent. This is a great way to soften the water for improved cleaning.

Some top tips for cleaning the VELUX window pane include:

  • Do not use any cleaning products that contain abrasive particles
  • Don’t use chemical products to clean the pane
  • Don’t attempt to clean dirt from the pane without using water first
  • Avoid any sharp objects from coming into contact with the pane – including jewellery
  • Avoid silicone from coming into contact with the pane

Cleaning the air filter in your VELUX window

Keeping the air filter within your VELUX window clean ensures the air that enters through the VELUX window vent is clean and free from particulates. This makes the environment within your home as healthy as possible.

You need to remove the air filter from the window to clean it. To do this, rotate the window into the 180-degree cleaning position as before. Then remove the filter from the filter rail.

Once you have removed the filter, you can clean it using ordinary household cleaners. Then put it back into the window.

Keeping VELUX flashings clear from debris

Remove leaves and other debris from the flashing which surrounds the window once or twice a year. This prevents blockages and build-up of debris. A problem that can result in allowing rainwater to run free instead of being blocked. Blockages can cause issues if not dealt with as soon as possible.

To clear the flashing, open the window as much as possible. Then run a handheld brush around the window surrounds, ensuring any debris comes away.

Preventing condensation build-up on VELUX windows

You may start to notice condensation building up on your VELUX roof window. Condensation is a build-up of moisture. This occurs when warm moist air reaches a cooler surface and condenses from vapour into liquid.

It is more common in winter when the temperature of the window is cooler. The warm moist air can be from cooking, cleaning, normal breathing, perspiration and more. Though it is not always an issue.

Preventing condensation from building up on your VELUX window is possible. The most basic step is limiting the amount of water vapour produced and increasing the amount of ventilation.

To do this, open the window on a regular basis to increase airflow, and add a heater or radiator below the window.
