What Causes Condensation?

The causes of condensation within our homes

Let’s take a closer look at what causes condensation in our homes.

Through the daily routine of showers, baths, boiling kettles, cooking, drying clothes and breathing a family of 4 will contribute approximately 4 pints of water per person a day, equal to over 100 pints of water vapour a week, which has to end up somewhere.

Before the days of double glazing, wall and loft insulation this humid, stale air would find its escape route through ill-fitting windows and doors, lofts and so on. It would be replaced by fresher, colder air or to you and me - a draught!

112 pints of moisture in a property per week

Three important factors that cause condensation:

  • The level of moisture in the air
  • The temperature of the air in your home
  • The surface temperature of the windows

The more moisture there is in the air the more likely it is that you will get condensation.

Today, after the introduction of energy saving measures such as draught proofing, double glazing and cavity wall insulation there is no natural escape route for this stale, humid air, which is now trapped inside the home. As a result, this trapped and stale air only makes the problem worse, causing condensation on windows, walls and poor indoor air quality.

Find out how careful planning can help to prevent condensation from building up in the home or rented property.
