What is Condensation?

Condensation is water which accumulates on cold surfaces such as on windows when moist air is in contact with it where the surface temperature reaches dew point causes the moist air to become saturated in kitchens and bathrooms.

Typical Visual Images

What are the signs of Condensation?

  • Water droplets on cold impervious surfaces such as window glass, pipe work and tiles
  • Visibly apparent localised or widespread mould or mildew growth on cold absorbant  surfaces such as plasterwork and/or woodwork
  • Visibly apparent localised widespread degradation of plasterwork, woodwork and/or decor 
  • Excessive airborne moisture detectable by the use of a Hygrometer
  • Excessive moisture content of plasterwork and/or woodwork detectable by the use of an electronic moisture meter, a Thermal Imaging camera and/or a Calcium Carbide meter.  

What are the consequences of Condensation?

  • Potential degradation of affected building materials
  • Potential risk of thermal discomfort of thermal occupant 
  • Potential excess heat energy costs for building occupants 
  • Potential risk of illness, disease and premature death of building occupants
