The effects of condensation
Condensation is the most visible effect of inadequate ventilation. Streaming windows and puddles on window sills are a common indicator of moisture build up. On average activities such as cooking and bathing mean that each person in the home produces four litres of water vapour per day. Unless this moisture is removed problems soon occur. Not just the inconvenience of wiping surfaces dry but the greater, potentially expensive, problem of mould growth ruining decoration.
Even the fabric of the building can be at risk if the condensation problem is not addressed. But condensation is not the only problem. A poorly ventilated home can mean the build-up of harmful gases. Building materials, paints, furniture and carpets all give off gases which can be detrimental to occupant’s health if not correctly dissipated. In some areas of the country the poisonous gas Radon can add to the potential increase of unhealthy pollutants. Modern airtight construction can mean a stale musty atmosphere high in carbon dioxide tainted with the odours produced by our everyday activities in the kitchen or bathroom. Altogether an unpleasant household environment!
Other health issues include the dust mite, a minuscule household insect that is a major contributor to the increase in Asthma cases. Dust mites thrive in moist conditions resulting in increased numbers with a corresponding rise in suffering.
For Hay fever sufferers summer may present a special problem with open windows allowing pollen laden air to permeate the building.
