Importance of Ventilation
The air we breathe indoors is a cocktail containing moisture, microbes, chemicals and
allergens, which affect human health and comfort. Many homes feel stuffy due to the
lack of ventilation.
The primary purpose of ventilation is to remove undesired airborne substances from
the building, especially moisture. It also serves to supply oxygen and remove carbon
dioxide from human respiration.

Reduce condensation
The moisture production from a typical family corresponds to emptying a large bucket of water on the floor every day.
Kitchens and bathrooms especially are areas where the build up of condensation is high due to the steam produced from showering and cooking.
Opening Skylights act as natural extractors of hot air and minimize condensation and mould growth, naturally. |

Natural Ventilation via the stack effect
The installation of VELUX Opening Skylights provides positive airing and Natural Ventilation. Skylights use the natural movement of air to extract moisture and volatile organic compounds, making a home healthier, dryer and more comfortable.
The Stack effect
The “stack effect” is the process of warm air moving upwards in a house. Warm air rises – because it’s lighter than cold air. It escapes out of the upper levels of our homes and gets replaced with fresher air from windows or doors.
