Moisture laden air from inside the home, and outside air can condense and
cause dampness. Ventilation prevents damage to ceilings and roof timbers,
helps control mildew. Shaded areas of your home particularly benefit.
Ceiling insulation is less efficient when wet, and as a result more heating
is needed to compensate. Ceilings can become mildewed too, good roof
space ventilation overcomes these problems and reduces costs.
In rooms that are most prone to mildew and mould formation, ventilation
helps to control the rapid growth that can occur. This occurs most when
humidity is present. A Spinaway ventilator is an energy free supplement to
an electrically powered extractor.
We recommend installation of two under eave vents to each Spinaway
installed to ensure correct operation.
