PIV Systems

Create a "good" draught in your home

Positive Input Ventilation (PIV) is a method of improving indoor air quality by installing a filtered ventilation unit in the loft that draws air through its filters and into the home. The unit creates a slight positive pressure throughout the home, causing polluted air to be pushed out through natural openings such as windows, doors, and vents. 

This technique was developed by Nuaire in 1972 and has since become the most popular way to enhance indoor air quality and eliminate condensation dampness in homes across the UK. Additionally, advanced filtration systems, such as a Nox filter, can be incorporated into the unit to ensure that harmful particles cannot enter the home.

The Benefits of Fresh Air

Reduce damp and pollutants

Just as humans need clean air to breathe to survive, your home too requires a constant flow of fresh, clean air to maintain a healthy and comfortable environment. Without it, pollutants can accumulate, leading to an unpleasant and potentially harmful atmosphere inside your property. By introducing clean air into your home, you can prevent the buildup of pollutants and create a pleasant, damp-free living space.
