Condensation Control

How to Treat Condensation

The problem of condensation can be controlled through three basic ways: by looking at relative humidity, ventilation and insulation. As specialists in condensation prevention, we can advise on which method is most suited to your property and help you treat the condensations where necessary.

1. Control humidity

You can control the relative humidity in your home through the use of extractor fans in kitchens and bathrooms. Shutting the doors to these rooms whilst the extractor fans work also helps.

2. Provide ventilation

It is important to ensure that there is adequate ventilation. Trickle vents in windows work well, but a more sophisticated option is a heat-recovery ventilation unit. These units replace the air in the home by taking the stale, damp air outside and bringing fresh air back in via a separate grille, passing it back over the heat exchanger to be warmed. It is also possible to buy central extract systems which connect all of the wet areas in your home to a central fan before discharging the stale, moist air outside.

Another ventilation option is a positive input ventilation (PIV) system that works by gently supplying fresh, filtered air into the property from a unit installed in the loft area and a distribution diffuser mounted in the ceiling. The continual supply and slight positive pressure results in the air being continually diluted, displaced and replaced to create a healthier indoor air quality.

3. Heating and insulation

Condensation can also be tackled by considering your heating and insulation. You may find that having your heating on constantly at a lower heat is better than it switching from high to off. Furthermore, as cold spots on walls or ceilings increase condensation, better insulation may bring improvements.

Your property may also benefit from cavity walls, a loft insulation or specialist insulation materials fixed to the outside of your house.

If you have single glazing, this may also be part of the problem. As with walls and lofts without insulation, single glazed windows will be a lot colder. If you do decide to install more insulation or double glazed windows, this needs to be balanced against good ventilation in your home (as mentioned above), or all the extra energy-saving measures could cause damp problems to re-occur.
