Condensation control and mould problems
Adequate ventilation in a property is essential for the well being of the occupants and the fabric of the building. This is reflected in current building regulations which require “adequate means of ventilation provided for people in the building”.
The most common consequence of inadequate ventilation is condensation. Condensation occurs when moist air comes into contact with a surface that is below its dew point. The air cools and can no longer hold as much moisture, which condenses on the surface forming condensation. Condensation can be a problem in new and old buildings.
Typical signs of condensation
The most common signs of condensation are:
- Streaming windows and condensation forming on windows
- Condensation water pooling on window sills
- Damp walls with no ‘tidemarks’
- Damp and mould patches
- Mould in corners of rooms
- Mould behind furniture
- Mildew on clothes and furnishings
- Musty and damp smells
Images above show mould in the corner of a lounge, severe condensation in the back of a wardrobe and heavy condensation on windows which are all indicators of condensation problems.
When does condensation occur?
Condensation usually occurs between October and April when outside temperatures are lower than inside. Energy efficiency measures such as double glazing and draught proofing have increased the occurrence of condensation and black mould in the modern home.
Why does condensation occur?
Condensation occurs when moisture in the air forms water droplets on cold surfaces like windows or outside walls. The moisture comes from a number of sources within the home including cooking, bathing, breathing, washing and drying clothes. A five person household can generate about 10kg of water every day.
What are the effects of condensation dampness?
Excessive condensation can lead to black mould growth, spoiling of decorations and damage to fabric items. Condensation and mould growth can lead to unpleasant odours, further reducing the air quality.
Dehumidifiers and anti condensation paints
Dehumidifiers are frequently used for the control of condensation. Although they can provide relief from excessive condensation they should only be considered as a temporary measure of controlling condensation. Dehumidifiers are costly to run to prevent condensation and require frequent emptying. Dehumidifiers and anti condensation paints just treat the effects of condensation and do not remove the cause.
How to prevent condensation?
Condensation occurs when heating, ventilation and insulation are out of balance and therefore the key to controlling condensation is to address one or more of these issues.
Steps to Control Condensation
Lifestyle changes to reduce condensation problems:
- Dry clothes outdoor or in a tumble dryer. If you most dry clothes in doors make sure the room is well ventilated or use a dehumidifier whilst drying clothes
- Ventilate bathroom and shower rooms externally during and after use, keeping the door closed
- Ventilate the building by opening windows, keeping ventilation strips on windows open and using extract fans
- Maintain an even temperature within the building. Avoid periods of very high or very low temperature
- Use an extractor fan when cooking or bathing
Building improvements to reduce condensation problems
- Improve insulation of lofts and cold walls
- Re-position or upgrade radiators in the cold areas
- Upgrade existing ventilation fans with run on timers or humidistat controls
- Add ventilation strips to double glazed windows
- Fit passive or mechanical ventilation to kitchen, bathroom and utility rooms
- Fit whole home ventilation systems to remedy severe condensation
Adequate ventilation can be maintained in a property through the use of various types of ventilation systems, including passive, extraction and positive input systems. Biocraft can specify and install all types of home ventilation system to prevent condensation, including the award winning PIV condensation system.
