What is Condensation?

Condensation in a house is the result of warm, moisture-laden air encountering colder surfaces, causing the air to release its moisture in the form of water droplets. This phenomenon is often noticeable in areas such as bathrooms, particularly after hot showers, and in cooking spaces where steam is produced. Uninsulated cold water pipes or tanks can also attract moisture from the air, leading to condensation. To prevent these issues, ensuring proper ventilation, addressing any water leaks, and managing indoor humidity levels are essential practices for maintaining a comfortable and dry living environment.

Reducing Condensation

As condensation is created by household activities, simply installing new windows will not fix the problem. There are a variety of methods to help minimise the chance of condensation.


1. Ventilation

proper ventilationProper ventilation is crucial to a healthy and dry home. Opening windows often and keeping them open, even a small amount, can help reduce condensation.

We offer options that allow our windows to be lockable while still providing natural passive ventilation.

Newer homes are built more airtight and have less natural airflow, so it is important that when performing tasks such as cooking, drying clothes, or taking a shower, you allow water vapour to escape outside.


2. Dehumidifiers

dehumidifiersThese devices draw moisture from the air in the room and deposit it into a container for disposal. They are useful for reducing moisture but can add extra costs as they use power to operate.



3. Double Glazed Windows

4. Thermally Efficient Windows

thermally efficient windowsThese help to reduce and prevent the transfer of heat energy through the window frames. This, therefore, helps reduce condensation on windows. These should only be used with Double Glazing.
