What is Condensation?

21st May 2024


Condensation can damage your property if not managed or avoided altogether, and can contribute to various health conditions such as allergies, asthma and other respiratory conditions.

So What is Condensation?

In a nutshell, condensation is the process by which substances change from a gas or vapour to a liquid, usually as a result of a drop in temperature. This is usually visible on windows, walls and ceilings inside your home.

What Causes Condensation?

Every household will generate warm moisture that gathers in the air. This will come from everyday activities such as cooking, bathing and washing. It will also come from our own breathing! When the moisture in the air comes into contact with cold surfaces, the process of condensation will convert it from a vapour to water droplets. A good example is the hot steam from a shower coming into contact with a cold mirror.

How to Control Condensation

A small amount of condensation can be normal in homes which have been built for a number of years, however, consistent moisture on interior surfaces is a clear sign that your home has a condensation issue. Condensation in your home is a direct result of high moisture levels and inadequate ventilation. Having a constant flow of fresh air throughout your property can help control and manage this condensation.

A Positive Input Ventilation System is the answer to your homes condensation problems! This is a small ventilation unit installed in a central part of the home, usually located in the loft-space above the hallway. The system provides a constant supply of fresh filtered air into the house, which forces the moist stale air out of the property through natural leakage points (this would typically be under doors, letter boxes, windows, chimneys etc), helping reduce the condensation issue.
