Condensation is an annoying and potentially damaging household problem that most homeowners will encounter at some point.
Signs of condensation include water droplets on windows and walls, damp patches, and mould. Condensation can look unsightly, cause damage to your home, and create unhealthy living conditions.
How is condensation formed?
Condensation is caused when warm water vapour in the air hits a cold surface. The cold surface cools the water vapour to a temperature that is below its condensing point, turning it from a gas back to a liquid.
Interstitial condensation versus surface condensation
There are two different types of condensation, interstitial and surface. The main difference between the two is where they occur.
Whilst surface condensation appears on the surface where it is visible, interstitial condensation occurs inside the layers of your building’s walls, roof or floor where it cannot be seen.
Of the two, interstitial condensation is usually the more damaging problem. As this type of condensation occurs within your building’s fabric, it may have caused considerable deterioration of your building’s internal elements before you notice the signs that there is a problem.
Top tips for banishing condensation
A few simple ways to reduce levels of condensation in the home include:
- Open vents, windows or doors when steam from washing or cooking is present.
- Keep the temperature in your home consistent.
- Ensure your home has adequate ventilation.
- Ensure your home has adequate insulation.
- Insulate your home using a water vapour resistant material like our spray-applied polyurethane foam.
