How It Works

PIV units are a whole home cure for condensation dampness in residential properties and its associated problems.


With products available for 2 and 3 storey homes with lofts, and purpose made designs for flats, apartments and basements. Both ranges are quick working and cost-effective,  making them an ideal solution for both new build and retro-fit applications.

PIV is a fit-and-forget technology that requires minimal energy to run and minimum effort to maintain. The PIV strategy, also known as an Alternative System within Part F of building regulations, works by gently introducing fresh, filtered air into the dwelling ensuring that old, contaminated moisture laden air is continuously diluted, displaced and replaced with good quality air. The result is improved air quality and a healthy living environment in which condensation cannot exist.

Positive Input Ventilation (PIV)

Without adequate ventilation, the moisture produced by washing, cooking and bathing remains trapped inside. Modern lifestyles, energy-efficiency measures such as wall and loft insulation, and the rise in energy prices all contribute to the problem. Added to this indoor pollutants such as burning fuel, using cleaning and beauty products create an environment that can be harmful to our health a PIV Unit provides a long-term solution that is easy to install in existing homes and uses very little energy.
