How to improve ventilation to reduce condensationThere are a few options to improve ventilation in your home:
Airflow system
Many new apartments are built with internal airflow systems to combat the problem. These systems use a network of ducts in the ceiling to extract and exchange air from the outside to inside.
This maintains air circulation and a humidity balance within a property that is well-sealed.
Retrofitting a ventilation system in a house is invasive and expensive and not always possible in older houses.
PIV Unit
For an easier to install solution, Positive Input Ventilation (PIV) units can be fitted in areas that produce excessive moisture. Such as kitchens and damp basements.
The unit extracts the humid air from inside the house and draws in ‘dry’ air from the outside. This exchange of air helps to maintain the humidity balance.
Extractor fan
Having sufficient extraction in a bathroom is essential to reduce the excessive humidity produced from showers. Some fans have humidity control and will allow the fan to operate automatically if the humidity level increases above a set level.
Kitchens also need good extraction systems for cooking to remove smoke, smells and moisture.
Air vents/bricks
Air bricks often get blocked to stop draughts, but they do work to keep an area ventilated. A simple vent will ensure the humidity is managed in a room, but this does have the result of energy efficiency being reduced. For this reason, air bricks are not as popular as they used to be.
Air vents in windows do work to help with ventilation and stop condensation on the window. They can be installed on most windows.
Opening windows
Your grandmother probably used to open the doors and windows every morning to ‘air’ her home. There is nothing better than allowing fresh air to circulate through a space to keep it ventilated, remove stale air and smells and to reduce moisture in the house.
Traditional windows were used to provide effective ventilation which was essential when most homes were heated by fossil fuels.
Sash windows were designed to allow for the bottom and top to be opened that would draw air in and out providing effective ventilation.
Bay windows were designed to have two casement windows on either side to allow superior draw and ventilation.
Transom windows above a door were designed to increase airflow around a property to move heat around internally and to ventilate.
Modern windows all have multi-point lock settings to allow them to be left open securely for ventilation. This is one of the simplest and easiest ways to keep your home ventilated and avoid condensation.
