PIV Units

Positive Input Ventilation (PIV) is the name given to a ventilation system or unit which transforms a stagnant and stale atmosphere into a fresh one. Creating a healthy and condensation-free environment by supplying a constant supply of fresh, filtered air to homes with a loft space.

PIV Units are an energy-efficient method of ventilating the home. It pushes out and replaces stale unhealthy air with drier fresh air. This is done by gently introducing filtered air into the home. Increasing the circulation around the property and improving the indoor air quality.

Damp, condensation and mould are unwanted nuisances that can crop up. Particularly in older premises during the colder months of the year. These problems can appear as though they were invited! They don’t stop at being visible pests either. They can damage walls, furniture and the overall aesthetics of your building.

By utilising a PIV unit, you will maintain relative air humidity at a stable level preventing both condensation and black mould issues. Immediately after you switch on your PIV unit, you’ll notice an improvement in air quality.

Yes – this is predominantly what PIV systems are designed for. By displacing humidity in the home and replacing the atmosphere with warm, dry air, condensation will be re-evaporated and forced out of the building.
