​How to stop condensation on my VELUX roof window

Hi there! Condensation on your VELUX roof window can be caused by excessive moisture in your home. To prevent condensation, you can try the following steps:

Reducing Velux Window Condensation Step by Step

  1. Check the seals: Make sure the seals around the Velux window are in good condition, as gaps in the seals can allow moisture to get inside and cause condensation. If the seals are worn or damaged, replace them with new ones.
  2. Consider using anti-condensation paint: Anti-condensation paint can help prevent condensation and is easy to apply. You can find this paint at most home improvement stores
  3. Reduce the air temperature: Keeping the air temperature around the Velux window lower can help reduce condensation. You can do this by using a fan to circulate the air or closing any curtains or blinds that are covering the window.
  4. Increase ventilation: Increasing ventilation in the room can also help reduce condensation. You can do this by leaving a window open slightly or using an extractor fan.
  5. Use dehumidifiers: If the condensation persists, you may want to consider investing in a dehumidifier. Dehumidifiers can help reduce moisture in the air and, in turn, reduce the amount of condensation on the window.
  6. Make sure your home is well ventilated. Open the window several times a day to allow fresh air to come in, and use fans or dehumidifiers to help circulate the air.
  7. Check the seals around your window. If the seals are not tight, warm, moist air can enter your home and create condensation.
  8. Install an insulated blind or shutter to help keep your home warm during the colder months.
  9. Make sure you are cleaning the window regularly with a cloth and warm soapy water.

I hope these tips help you reduce the condensation on your VELUX roof window. Good luck!
