Loft Insulation PVI System - How It's Work. Vector Illustration

It works by drawing pure air into the void of roof or straightaway into the flat where the Positive input ventilation system (PIV) unit filters it. Then, the built-in air heater tempers the filtered air. It is then drawn into the living area. This extra inflow of air leads to a little positive air pressure that compels moisture laden and stale air go out of the home via leakage points that are available. Kitchens, bathrooms and other spaces need extraction fans which can ensure a full ventilation solution for the entire home.
