For years ventilation companies have used flexible ducting for sub-floor ventilation. A new approach, however, is now available from Envirofan.
Envirofan’s approach is cutting edge in design and installation methods. Envirofan has steered away from conventional methods, as it is Environfan’s belief to maximise sub-floor ventilation without obstructions. The obstructions not only pertain to the building itself such as subwall and central heating ducts, but the materials used by ventilation companies to solve ventilation issues by installing more ducting, and other paraphernalia used in association with the ducting configuration.
Envirofan induces dry air from the outside and force it into the underfloor area by the use of solarpowered ventilation systems, which is installed on the exterior or by the utilisation of wire mesh vents. Envirofan then uses bricksize ventilation systems that are established in the subwalls to direct air flow from room to room at a rate of 2.5m3/per minute at 27db; extraction ventilators, which are mounted on the other side of the home preferably on the east or south aspect draw the damp air out. In exceptional circumstances whereby there is no accessible exit point for an extraction system, the use of flexible duct to the nearest external point is unavoidable and is used sparingly.
Envirofan continues to maximise airflow in sub-floor areas not only by using quality products, but by keeping sub-floor free from obstructions after Envirofan are done.
