Envirofan offers inputs on fan-forced sub floor ventilation system. To clarify damp solutions it is not referring to rising damp whereby the damp course has failed in the brick work. Sub floor ventilation becomes effective where the entrapped humidity is expelled and the most effective way in extracting this moisture laden air is by utilizing fan-forced sub floor ventilation systems. This is how sub floor ventilation systems can provide a damp solution in this respect.
If rising damp is the issue then a rising damp specialist should be consulted in providing damp solutions by the installation of a physical damp course or by injection damp course. When passive vents are coupled with fan-forced sub floor ventilation systems then the solutions for damp are maximized.
To illustrate this point when newly laid floors are installed after they acclimatize, there is a tendency for it to expand creating problems such as cupping, bowing, lifting and warping. A very effective way of providing solutions for this damp problem is by utilizing fan-forced sub floor ventilation systems.
The fan-forced sub floor ventilation system physically extracts the humidity underneath the floor creating a drier environment thereby lowering the ambient moisture level in the timber flooring which leads to contraction of the material. Damp solutions can be three pronged in this example as a drier underfloor area will inhibit the opportunity for termites to establish themselves within the property.
Air quality inside the home can be greatly improved as the moisture laden air which propagates mould and mildew spores normally penetrates through the flooring is re-diverted by the fan-forced sub floor ventilation system thus providing solutions for damp.
