Positive Input Ventilation (PIV) Systems
A Positive Input Ventilation (PIV) system is an effective solution designed to help reduce condensation, mould growth, excess humidity, and poor indoor air quality within residential properties.
PIV systems work by gently introducing fresh, filtered air into the home. Air is drawn into the unit, passed through specialist filters, and then distributed throughout the property at a controlled rate.
As the fresh air circulates, it creates a continuous positive airflow within the home. This process helps to dilute, displace, and eventually replace stale, moisture-laden air.
Because the air within the property is constantly moving, humid air is less able to settle on colder surfaces such as:
- Windows
- External walls
- Ceilings
- Corners of rooms
This significantly reduces the likelihood of condensation forming and helps prevent black mould growth.
The excess humid air is then naturally forced out of the property through existing leakage points such as:
- Window vents
- Gaps beneath doors
- Air bricks
- Passive vents
- Natural airflow gaps within the building
Benefits of a PIV System
- Helps reduce condensation and mould growth
- Improves indoor air quality
- Reduces excess humidity within the property
- Creates a healthier living environment
- Helps eliminate stale and musty odours
- Low maintenance and energy efficient
- Suitable for occupied homes with minimal disruption
