6. Edwards Handbook of Domestic Ventilation Elsevier Butterworth Heinemann 2005 HOW CAN I PREVENT DAMP CONDENSATION AND MOULD Firstly it is necessary to make cooler surfaces located on the external walls less prone to condensate and mould You can achieve this by improving air circulation around these areas and to let the ambient room temperature get at the cold surfaces and thereby increase the surface temperature above the dew point This can mean using thinner curtains pulling the bed wardrobe away from the wall and rearranging the room to stop insulating the cold external wall surface Secondly you need to regularly clear any signs of mould Polycell 3 in 1 Mould Killer please remember to use gloves will kill mould spores You need to throw out any material items that smell of mould and will not wash out Thirdly you need to establish where and why certain areas in your house are affected by condensation and mould Please think about the following moisture sources metabolic evaporation cooking washing clothes drying clothes indoors dishwashing washing bathing etc All of these generate moisture in to the air Fourthly what is happening to the moisture created in your kitchen and bathroom Do you have auto matic ventilators fans Are they effective Do they have humidity controllers Ideally you should also have a passive air vent at high level in your bedroom HUMIDITY AND CONDENSATION Humidity is a term used to describe m

8. automatically extract at high level to remove moisture that has just been created at source for example when cooking or bathing This is when air has the highest humidity and vapour content and is most likely if not extracted to migrate to colder parts of a property and condense By continually extracting air the nascent moisture is removed but also in effect it creates a vacuum which will suck air in from areas of least resistance such as through floor boards and through service vents which usually have high levels of contamination or stagnant air associated with them Without replacing the air it is also possible to cause undesirable short circuiting of air flow to gas appliances Passive ventilation provides a structured solution for air management where the positioning of the vent s dictates the air movement though the building The increased movement of air will also have an overall drying effect Part No Kit Contents Vapour Vent 125mm 125 125mm diameter telescopic tube internal vapour membrane external and internal grille Vapour Vent 150mm 150 150mm diameter telescopic tube internal vapour membrane external and internal grille Vapour Vent 150mm with high V150P 150mm diameter tube internal vapour membrane push through circular external grille level push through grille with seal internal grille 17 WOLF B amp WOLF B TWIN auto low watt bathroom fans The ultra energy efficient WOLF B bathroom fan is designed f
