Wood Maintenance

maintain pine roof window

Although most of our products are now pre-painted, some still maintain a natural wood finish. The timber has received basic treatment and finished coating at the factory and can be cleaned with ordinary household cleaners. It must receive further treatment at least every four years and whenever required. Windows exposed to strong heat, strong sunlight and/or an especially high level of humidity (e.g. in a kitchen or bathroom) must however receive treatment at least every two years.

Surface maintenance: Remove surface treatment (varnish or paint). Ensure surface is clean and dry and apply primer to the timber. When dry, apply a coat of water-based acrylic varnish/paint (always follow the manufacturer’s directions). Apply the same method to the affected areas if the varnish/paint is damaged.

When you treat the wood, it is important to cover the gaskets to prevent varnish/paint rubbing off on the gaskets, as this will make the gaskets stiff/hard and spoil their effect.

Cleaning the pane

Clean the pane with a soft, clean, lint-free cloth/chamois leather/nonabrasive sponge or a clean, non-metal window squeegee. Clean water will normally be sufficient for cleaning the pane. Ordinary, non-abrasive household cleaners can also be used. Soft water is best for cleaning panes. Therefore, in hard-water areas add a small amount of detergent to soften the water or wipe off all excess water after cleaning.

  • Avoid contact from silicone with the pane
  • Do not use any cleaning products containing abrasive particles
  • Do not use chemical products for cleaning the pane
  • Avoid contact with the pane from all sharp or abrasive objects including jewellery
  • Never attempt to clean off dirt on the pane without first applying water
  • If any works are taking place in the vicinity of the pane, protect the pane with a clean plastic sheet to prevent any splashes or staining from aggressive and abrasive compounds

Cleaning the air filter

Air filter is the thin foam-like strip that lines the internal railing of the window. This filter catches small dust particles that travel through the open window, so it’s important to clean it regularly.
The air filter can be removed and washed with ordinary household cleaners. Fully rotate and secure the window in cleaning position, then remove the filter from the filter rail. New filters are available can be bought as part of a maintenance kit (ZZZ 220).

Cleaning the flashing

Flashing is the layer that makes your window and roof material fit together. Rain will keep most dirt and grime off of the exterior surfaces.

However, depending on where you live, leaves and other debris will sometimes collect around your windows and should be re moved from the flashing around windows and skylights once per year to allow rain water to flow freely.

A stiff-bristled brush can be used to remove any leaves or excess dirt and debris.

Cleaning The Frame

Your roof window could be white, pine of PVC, depending on the model you have installed.

Each of these different finishes can be cleaned similarly. Simply take a dry cloth and wipe down the edges of the window frame to remove any collected dust. Towels made from a microfibre fabric typically work best because the dust particles cling to the fibers of the cloth.

If you end up with smudges on the frame that is unable to be taken off using a dry cloth, then follow behind with a damp cloth. If this does not work, then use a bit of multipurpose cleaner to remove the smudge.

If you have centre-pivot roof windows, simply rotate the window and repeat this process on the other side.

Cleaning The Inner Pane

Start by cleaning the interior side of the glass. Use a soft, clean, lint-free cloth/chamois leather/non-abrasive sponge or a clean, non-metal window squeegee. Water alone should be enough to effectively clean the glass, but for a brilliant shine, spray a little bit of non-abrasive glass cleaning solution on the pane and remove immediately with your cloth or squeegee.

Soft water is always the best when it comes to cleaning the window panes as it can provide your window with a streak-free clean, but if you happen to live in an area that has hard water, then just a tiny amount of detergent will be enough to soften the water and leave your window spotless.

If you’re using a squeegee, use care not to touch any metal parts of the cleaning equipment to the glass or let any abrasive materials be dragged across the glass surface. Avoid any contact with metal scrapers, blades or knives as this can easily scratch and cause permanent damage to the skylight glass.

We recommend you follow these tips In order to get the best results:

  • Do not use any cleaning item that has abrasive particles.
  • Do not clean the roof windows during the hottest parts of the day.
  • Do not use any harsh chemicals to clean the panels.
  • If there are multiple skylights, start at the highest and end at the lowest.
  • Avoid any contact with the panel from abrasive or sharp objects which include jewellery.
  • Avoid making contact with the silicone on the pane.
  • If you are doing work around the rooftop window, then protect it using a clean plastic sheet to prevent stains or splashes from abrasive or aggressive products.
  • Do not try to clean the dirt off of the panel without applying water as it may cause scratches on the surface.

Cleaning The Outer Pane

The best part about roof windows, is that the window panels are very easy to clean on both sides. Instead of having to use a ladder to climb on your roof to clean the window or having to hire a professional, you can access both sides of the window from the safety of your home.

To clean the outer pane, rotate the sash 180 degrees. The sash must be secured in position by sliding the barrel bolt into the bushing at the bottom of the side frame. This safety feature leaves both hands free for cleaning. Then, follow a similar process as above.

The outer pane of your window will have a lot more dirt than the inside of the window. Be sure to use a wet cloth to wipe off the top layer of filth and then use a clean, wet cloth to clean off the glass cleaner.

Removing snow and ice

In areas with prolonged cold periods with heavy snowfall, considerable amounts of snow and ice may accumulate on the roof and a VELUX roof window could become covered with snow and ice for long periods.

When the temperature rises, the window will often be one of the first places where the snow and ice starts melting.

It is important to make sure that water can always drain off from the roof and surrounding gutters.

Eliminating Condensation

When condensation forms on the glazing of your windows, you should take it as a warning sign that you should ventilate more often. Regular ventilation is the most efficient way of preventing condensation water from forming on your window glazing.

Limit the amount of humidity:

  • If possible, do not dry your laundry inside the house.
  • Close the doors of kitchens and bathrooms.
  • Ventilate regularly for five minutes at least three or four times a day
  • If possible, maintain a constant room temperature of at least 68°F.

Cleaning the hinges

Be careful cleaning the hinges of your rooftop window. Hinges may rust or collect grime over time, especially if you live near the seaside.

However, VELUX windows are built to last, so if you notice that the hinges are not moving as smoothly as they used to, it might be a sign that it’s time to replace you rooftop window.
