How to Stop Skylight Window Condensation

As with many other windows, skylight window condensation can be a problem for homeowners and usually forms as the result of humid, warm air rising and reacting with the cold window glass, made so by chilly outside temperatures. Consequently, the air begins to liquefy, forming small beads of water which then slide down the window and cause the surrounding area to become damp. Not only can condensation on skylight windows make the window pane hazy and wet but if the window has been poorly fitted, it can also cause the wood panelling to become swollen, potentially causing gaps in the window that may enable cold air to seep into your home. To stop condensation from forming on your skylight windows, we’ve put together a short guide to help you tackle condensation in your home:

Internal Causes of Condensation

Many activities that we do on a day-to-day basis can contribute to condensation forming on glass surfaces within our homes. These include:

  • Breathing
  • Perspiring
  • Showering
  • Baking
  • Cooking
  • Watering indoor plants
  • Bathing and showering

Each of these activities (some of which cannot be helped) cause moisture to form, making the air in our homes damp and dense. As a result, this moisture then condenses and settles on cold glass surfaces such as window panes.

How to Identify Condensation

There are several tell-tale signs to watch out for that signify condensation is forming in your home such as:

  • Hazy/wet window panes
  • Wet walls
  • Flaky or bubbling wallpaper or paint
  • Mould or damp patches on walls and ceilings
  • Damp or deteriorating furniture

If you spot any of these signs in your home, you may have a condensation problem that will need to be addressed. One way to do this is to improve the ventilation system within your home.

How to Keep your Home Ventilated

Effective ventilation within the home can halt condensation in its tracks, meaning you will no longer need to worry about wet patches forming on the inside of your window panes. For truly successful ventilation, it is important to substitute moist air inside your home for dry air outside it. To do this, you must:

  • Open windows in various rooms to let fresh air flow through your home
  • Switch on internal fans when showering, bathing or cooking
  • Keep curtains and blinds open during the day to enable warm air to reach your window panes
  • Try not to overuse appliances in the home that could produce too much warm or damp air such as kettles, irons or tumble dryers
  • When possible, hang wet clothes outside instead of inside to dry

Proper Installation

Additionally, make sure your skylight window is fitted properly to stop condensation becoming a problem in your home. As previously mentioned, a badly installed skylight window can lead to small gaps forming in the outer panels of the window, allowing cold and often damp air to break through into your home. Additionally, this outside moisture can then cause wooden panelling to swell, causing a loss of insulation and making it more likely for rising hot air to liquefy.

Get the Right Blind

Having the right blind can also prevent condensation from occurring on your skylight window pane. Here at Skylight Blinds Direct, we offer a range of skylight window blinds made from both thermal and waterproof fabrics that can help stop condensation forming on the inside of your window.
