hen people talk about ventilation they think of the extract unit, taking the
air out of the building. A ventilation system is more than just extracting air,
it also relies on the replacement of the stale air with fresh, clean air.
Whether you’re using a Passive Stack system, a Mechanical Extract system or
even intermittent extract units, the building regulations call for a set amount of
background ventilation for each ventilation strategy.
To avoid condensation extraction of warm, moist air is not enough, it has to be in
conjunction with input of fresh air, yet this is often over looked for a number of
different reasons. The fresh air not only creates a fresh atmosphere, it also promotes
air movement to ensure that air is circulated around the property.
There are many cases where people have a sufficiently working extract system yet
still experience condensation within properties, and the main reason is because of
insufficient fresh air.
Passivent offer a range of background ventilators to enable fresh air to be input in to
a building to ensure a healthy atmosphere and reduce the potential for condensation
and mould.
Standard and acoustic window and wall vents
Passivent standard window and wall vents are designed to allow air to enter the
building to provide the stated levels of background ventilation to meet the
requirements of Building Regulations. Geometric free areas are shown for Scottish
Building Regulations.
Passivent acoustic window and wall vents not only provide the stated levels of
background ventilation, but also noise attenuation for buildings which may be
situated where external noise could pose a disturbance to the occupant.

With manual controlled vents there is the reliance on the user to open and close the vent as required. If they do not use the product as is required, it is possible that dwellings are over or under ventilated. Over ventilating will mean that excess heat is lost, thus requiring more energy from the house heating to warm the space, costing more money. Under ventilating can lead to issues of condensation and possible mould growth.
An automatic unit, such as the Fresh 99H opens and closes dependent upon relative humidity, thus reducing the potential for condensation and reducing the amount of heat loss.
The product does not require any manual interaction to operate, making ideal for social housing, care homes, hotels and student accomodation.
