The Importance of Clean Air and Ventilation in Your Extension
Gary Newell • 1 June 2024
At Jigsaw Construction Surrey, we're passionate about creating beautiful, functional extensions that transform your home. But a stunning extension isn't just about aesthetics – it's about creating a healthy and comfortable living environment. That’s why we prioritise proper ventilation and air quality in every project we undertake.
Why is Clean Air Important in Your Extension?
Believe it or not, the air inside your home can be [1]2-5 times more polluted than the air outside. This is because everyday activities like cooking, cleaning, and even breathing release pollutants into the air. In a poorly ventilated extension, these pollutants can become trapped, leading to a range of health concerns, including:
- Respiratory problems like asthma and allergies
- Headaches and fatigue
- Eye irritation
- Difficulty concentrating
The Benefits of Proper Ventilation in Your Extension
By incorporating a well-designed ventilation system into your extension, you can:
- Reduce pollutants: Fresh air dilutes and removes harmful contaminants, creating a healthier environment for you and your family.
- Control moisture: Proper ventilation helps prevent condensation and mould growth, which can damage your extension and trigger allergies.
- Improve comfort: Fresh air circulation keeps the temperature and humidity levels comfortable, especially important in well-insulated extensions.
- Boost concentration: Good air quality can improve focus and productivity, perfect for creating a home office in your extension.
Different Ventilation Options
In the UK, we have several ventilation options to consider for your extension, both natural and mechanical:
Natural Ventilation:
- Windows: This is the most basic and cost-effective option. Strategically placed windows allow for fresh air to enter and stale air to escape. You can consider tilt-and-turn windows for more flexibility in controlling airflow.
- Window trickle vents: These are small vents built into modern windows that allow for a constant trickle of fresh air, even when the window is closed. This helps maintain background ventilation, particularly important in new, energy-efficient extensions where gaps and cracks have been sealed.
- Air bricks: These are bricks with built-in vents that allow air to enter and exit the building through the walls. They are most commonly used in older homes but can be incorporated into new extensions as well.
Mechanical Ventilation Systems:
- Extractor fans: These are typically installed in kitchens and bathrooms to remove moisture and odours. They can be intermittent or continuous.
- Continuous Mechanical Extract Ventilation (MEV): This system uses low-powered fans to continuously extract stale air from wet rooms like bathrooms and kitchens.
- Continuous Mechanical Balanced Ventilation with Heat Recovery (MVHR): This is the most sophisticated option. MVHR systems extract stale air while simultaneously bringing in fresh air. They also recover heat from outgoing air and transfer it to incoming fresh air, improving energy efficiency. This can be a good option for larger extensions or those in areas with colder climates.
Choosing the Right Ventilation Option:
The best ventilation option for your extension will depend on several factors, such as the size and layout of the extension, the number of occupants, and your budget. Take a look at the building regulations for more information.
