Moisture and
Condensation
Condensation is generally more noticeable on
skylights because warm, moist air rises to the
ceiling and meets the colder glass surface.
The problem doesn’t usually arise from the
skylight, but rather from the excess moisture
in the room compared to outside. And since
we can’t control the weather outside, let’s
talk about how you can use your skylights to
combat condensation inside your home.
PREVENTING EXCESS MOISTURE
Condensation is a moisture problem, but
we’ve compiled a list of some suggestions that
can help air out your home to reduce excess
moisture and humidity.
• Use VELUX ACTIVE to detect humidity
levels in your home. When those levels get
too high for comfort, VELUX ACTIVE will
automatically open your skylights then close
them again once humidity levels balance
out.
• Open your skylights during everyday
activities that create humidity, such as
cooking, cleaning, or showering.
• Set an alarm on your phone (or use VELUX
ACTIVE) three times a day to remind
yourself to open your skylights for 10
minutes. Regular daily airings can
help naturally reduce pollutants and
humidity in your home’s air.
• Open wall windows at the same time
as your skylights for whole-home air
circulation. Hot, humid air escapes through
your skylights as cool, fresh air comes in
through the windows in a phenomenon
called the Chimney Eect.
• To help your skylight with the heavy lifting,
run a dehumidifier during winter months
and damp weather. You can also take
shorter showers and cook with lids on pots
to reduce moisture in the air.
• For an overall more energy-ecient home,
opt for double-paned, insulated windows
and doors with Low-E glazing.
• Install vents below windows to help warm
the interior glass.
• Vent any tumble dryers and gas appliances
to route moist air outside the home
