Condensation in Buildings
Seminar length: 45 to 60 minutes
Condensation and the associated mould growth is the most commonly encountered damp problem for building occupants and owners. If left to develop, condensation problems can have a significant effect on building occupants. A building suffering from condensation issues is unpleasant to live in. Mould can destroy possessions and also exacerbate health problems
The seminar offers a detailed insight into the causes and effects of condensation and the wide range of modern-day treatments available. The benefits and drawbacks of each treatment method in relation to the severity of individual condensation cases are discussed. The presentation gives attendees practical knowledge to go out and solve condensation and mould problems.
Topics covered include:
Why is Condensation Important?
- It can be unsightly
- It can cause a ‘damp’ feeling or musty smells
- Leads to mould and health issues
- Can lead to deterioration of the building fabric
- It is a legal requirement for new build and rental properties to be free from damp
What Causes Condensation?
Water and air exist in balance. The air all around us always contains a certain amount of moisture in the form of water vapour. Warm air can hold more water vapour than cold air. If high-humidity warm air becomes cold, then there is too much water vapour for it to hold and, as a consequence, the extra water condenses on cold surfaces.
Methods of Condensation Treatment
- Using data loggers
- Making lifestyle and routine changes
- Improving ventilation
- Increased level or heating or insulation
- Using anti-condensation or anti-mould paints and cleaners
Which Method is the Right One?
The best methods for dealing with any individual condensation problem may differ significantly depending on variables such as the severity of the problem, the type of building construction, the available budget, the level of access to the property and intended purpose of the space. For example, an occasional small occurrence of mould in a bathroom during the winter months will require a much different approach than a sustained mould problem throughout a large residential block all year round.
