Condensation is probably the most common type of dampness in buildings. Condensation can cause mould growth on walls, ceilings, curtains and clothing and can lead to peeling wallpaper and many other problems.
Insufficient ventilation, poor heating, lack of insulation, lifestyle and multi-occupancy, such as student accommodation, are commonly result in cases of condensation. Flats and bungalows are especially prone to condensation problems being constructed in one storey without the benefit of a greater circulation of air through the staircase.
BAR Preservation along with leading British specialist ventilation manufacturers can offer Positive Pressure Ventilation Systems to help eradicate condensation.
What Causes Condensation?
Most people think that mould growth, musty smells, streaming windows, wet curtains or pools of water on window sills are caused by rising and penetrating damp, however this is not always the case. Quite often the problem is caused by condensation.
BAR Preservation Can Help Reduce Condensation
Heat Recovery Ventilators
To cure condensation in single rooms or small dwellings BAR Preservation often recommend a heat recovery ventilation system. This system provides a continuous change of air; continuously replacing stale damp air with fresh, filtered, warmed air from outside. Heat recovery ventilators are economical and recover around 73% of exhaust heat; replacing conventional extractor fans with heat recovery systems could save more than half of the energy used.
Positive Input Ventilation
For a whole house, a positive input ventilation system is usually recommended. The main ventilation system is usually placed in a loft space to utilise the dry and relatively warm air found there to provide a continuous supply of fresh air to the whole property. Via an inconspicuous, unobtrusive vent, usually positioned in a central point of the dwelling like the top of the stairs or in a hallway ceiling, the system gently replaces stale moist air found in the house with clean dry filtered air.
The fresh dry air mixes with the existing air and distributes throughout the whole of the property. The whole house then becomes slightly pressurised with new fresh dry air circulating throughout the property, thus eliminating any stagnant pockets of air. The slight positive pressure causes air to gradually leak out through windows, doors, grilles and other natural crevices leaving drier, filtered air left within: A significant improvement is often seen within a few days of installation.
As well as removing the problem of condensation these systems also help remove fumes; from tobacco and exhausts, chemical emissions; from furnishings and cleaning products, dust; from furniture, carpets and bedding, and pet odours. These systems typically cost from a penny per day to run.Back Arrange A Survey
