What is Condensation?
Condensation can damage your property if not managed or avoided altogether, and can contribute to various health conditions such as allergies or asthma. So what is condensation and how can it be controlled with the use of adequate ventilation?
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. So what substances will cause condensation within the home? 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! The moisture that is in the air will then come into contact with cold surfaces and 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
Having a constant flow of fresh air throughout your property can help control and manage condensation. A Positive Input Ventilation System
is a small unit installed in a central part of the home, usually in the loft 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 to reduce the condensation issue.
