Installing single room extract fans will help you meet the minimum ventilation requirements in current Building Regulations and are a simple and cost-effective method of doing so.
Our intermittent extract fans are a simple and easy to install ventilation strategy for wet rooms and kitchen ventilation.
How Intermittent Extract Fans Work
To comply with Approved Document F using an intermittent ventilation strategy, extract fans must be installed in all wet rooms and meet the minimum extract airflow rates specified in the building regulations.
To ensure adequate whole-home ventilation, intermittent fans must be paired with correctly sized background ventilators, such as trickle vents in windows, to allow for replacement air. In highly airtight modern homes, additional or larger background vents may be required to ensure intermittent extract fans perform effectively.
