Condensation accounts for 70% of reported domestic damp and is undoubtedly a contributing cause of of damage to walls and furniture.
Condensation can commonly be attributed to a lack of balance between heating and ventilation, resulting in a rise in relative humidity. Air can hold more water vapour when warm than cold. As warm air is cooled, such as when the heating is switched off at night, it will deposit the water that it can no longer retain as condensation on a cold surface. A similar effect can be demonstrated by breathing onto a mirror or other cool surface.
When the heating goes off at night the air temperature inside the house drops. This cool air cannot retain the same amount of water vapour as the warm air, and when the warm air comes into contact with a colder surface, such as an outside wall or window, it will deposit the moisture it cannot hold onto that surface. This causes misted or streaming windows, and in extreme cases walls that are wet to the touch and black mould growth.
Condensation is most common in the colder months of the year when the heating is turned on and windows are kept shut. It will also occur if there is a lack of ventilation in a property particularly in rooms which generate a lot of moisture, mainly bathrooms and kitchens. Property layout, living habits, number of occupants and insulation can all effect condensation levels.
PROBLEMS ASSOCIATED WITH CONDENSATION
In its less serious form, condensation may steam up windows and mirrors. In more severe cases, it can be absorbed by surface wall finishes and underlying plaster, which can cause dampness, although the under-lying brickwork or masonry will normally be of relatively low moisture content. Left untreated in a property, condensation and the increased moisture it creates in the air can lead to a range of problems, such as:
- Damage to walls, plasters, timbers and furnishings
- Mould, which as well as being unsightly and damaging to a property can also aggrevate asthma and produce allergic reactions similar to hay fever due to the sportes the mould produces
- High humidity levels in the property, which creates an ideal environment for the spread of bacteria, viruses and the breeding of house dust mites
- Contributing factor to beetle infestation and fungal decay
OUR SOLUTIONS AND PRODUCTS
Our most successful cures for condensation are Drimaster and Flastmaster units. These are from our range of positive pressure units and humidity controlled extracts, which actively introduce tempered, filtered air into the property creating a slight positive pressure and total air change every 45 minutes or so. Moisture laden air is expelled through the natural ‘’breathing holes’’ found in all properties.
With both of these products we offer a 60 day money back guarantee subject to the terms & conditions contained in our quotation and order form, and a five year manufacturer’s product parts warranty.
