One of the most common causes of dampness in buildings is ‘condensation’. Moisture is always present in the air, even if it cannot be seen. Cooking, heating, showering and washing and drying clothes further elevate moisture levels in homes.
Warm air holds more moisture than cold air. When warm air is cooled the amount of moisture it can hold reduces. If cooled far enough the air releases its excess moisture, forming droplets of water on sufficiently cool surfaces. This is known as ‘condensation’.
In the home condensation is most noticeable on cold mornings, often seen on windows, on the inside faces of external walls, or in places where air movement is restricted, such as in the corners of rooms and behind items of furniture placed close against walls, and even inside wardrobes.
The presence of condensation is often first indicated by the development of mould on walls, ceilings, and even furniture, clothes and other fabrics. Condensed water can go on to provide sufficient moisture to allow timbers to rot. Condensation is most problematic during the cold winter months, with the October to April period generally acknowledged as ‘condensation season’, although it can occur throughout the year.
To minimize surface condensation, it is necessary to do one or more of the following:
a) obtain low vapour pressures by ventilation (Extractor Fans/Units, Positive Input Ventilation Units & Passyfier Air Vents and/or reduced moisture input to the building;
b) obtain high surface temperatures by providing more insulation and/or increasing the heat input.
All our ventilation installers hold electrical (Part P) and ventilation (Part F) qualifications. See the full list of qualifications held by our staff on our meet the team page.
We offer three types of positive input ventilation systems.
The Auto Concure 20/20 loft mounted unit, Concure 20/20 wall mounted unit and Sano IPIV loft mounted unit.
We offer a range of different units to be able to meet the many different requirements of different properties.
PIV units have been preventing and curing condensation dampness related problems in homes for decades. They are also used to control other indoor air pollutants and have even proven to be an effective means for reducing Radon gas in some properties.
A positive input ventilation system gently forces air from the loft around a building. It reduces humidity and eliminates condensation, black mould and mildew. It is an effective and inexpensive way of eliminating black mould and takes maximum advantage of solar gain and warm air stratification.
Overall savings in central heating costs may be possible due to the recirculation of warm air at ceiling height.
The units are idea for most domestic properties, and also for second or holiday homes that are used infrequently. The constant stream of ventilation means the property will always be well aired and welcoming.
The unit is positioned in the loft above the landing in a house or central hallway of a bungalow, the system then re- circulates air to a temperature of 10 degrees Celsius.
The units have an intelligent electronic controller which is used to control the fan, heater, sensors and safety cut-outs, and can be adjusted to suit the size of the individual property.
