The essentials of house ventilation

Ventilating a home helps to develop a healthy living environment– learn how and about the different ventilation methods offered to property owners.

What is ventilation?

Ventilation is the exchange of air between the interior and exterior of a dwelling. The main function of ventilation in a house is to remove polluted indoor air and replace it with ‘fresh’ outdoors air.

Why is it required in my house?

The distributing air reduces the danger of risk from hazardous indoor contaminants being produced within the home. This helps to offer a healthy and comfy internal environment for the residents of a house.

The Building Regulations Advisory Committee in England and Wales need ‘that there will be adequate ways for ventilation provided for individuals in the structure.’

In Scotland the Building Standards state that ‘all structures need to be ventilated so that the air quality within the structure is not a hazard to the health of the occupants or the building itself.’

Main types of ventilation

Purge ventilation

Sometimes described as quick ventilation, this is the fast exchange of large amounts of air in between spaces or in between a room and the outdoors, and is typically attained by opening a window or a door.


Assists with elimination of periodic contaminants such as smoke and smells from cooking, or fumes from painting and designing

Stops a house from getting too hot and uncomfortable during warm summer season durations

Extraction ventilation

This is the active extraction of air from rooms through mechanical ways, usually with a fan or a/c unit.

Extraction ventilation is needed in rooms that are routinely exposed to toxins or excess water vapour such as kitchens and bathrooms. Such spaces can utilize permanent or intermittent extraction.


Limits the spread of fumes and pollutants throughout a residence

Background ventilation

This is the passive flow of air into and out of rooms through vents, and is attained by means of ‘a little ventilation opening developed to offer controllable ventilation throughout an entire structure’.

Background ventilators ought to preferably be placed 1.7 m above flooring level to avoid noticeable draughts.

Trickle ventilators are perfect for meeting this requirement. Different devices can be utilized to open and close vents to match the activities of the home’s residents.


Background ventilation through drip ventilators can provide a house with a safe, draught-free and consistent supply of ventilation even when windows are secured a closed position
