The Glidevale iPSV®
intelligent passive stack ventilation system provides an ultra-low
maintenance, no-energy alternative to mechanical ventilation. 
Driven primarily by the
natural stack effect by which warm air rises, moisture-laden air is
removed directly from 'wet' rooms (e.g. kitchens and bathrooms). Air
inlets located in habitable rooms (living rooms, bedrooms etc)
provide a flow of replacement air to the building. 
A variety of wall
inlets are available under the Glidevale Fresh vents range. Please
contact us for more information.
