Window Ventilation

The design of your home, school, office or hospital requires three elements that work in harmony: heating, insulation and ventilation. Each of these elements are vitally important to the quality of the indoor environment and therefore the well being of the occupants.
To ensure this balance is maintained, the Building Regulations state the minimum levels of ventilation that is required (see page 5).

Ventilation helps to prevent the build up of fumes from products within the building plus the natural gases such as radon and methane. Permanent ventilation is essential to help prevent the build up of carbon monoxide gas which can be lethal within an enclosed area.

Ventilation within buildings is necessary for the health of the occupants and also for the life cycle of the building materials. For instance a normal family of four produces on average 10 litres of water every day in the form of water vapour just by breathing, washing, cooking and bathing. Therefore a continuous airflow is essential to prevent condensation, to remove moisture and pollutants such as tobacco smoke.

Below are some examples of the systems available, for a brochure with the full range of systems available please contact us.
