Positive Input Ventilation (PIV)

Positive Input Ventilation (PIV) work as a whole house ventilation system and create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout. 

A balanced ventilation system usually has two fans and two duct systems. Fresh air supply and exhaust vents can be installed in every room, but a typical balanced ventilation system is designed to supply fresh air to bedrooms and living rooms where occupants spend the most time.

PIV ventilation units work by ensuring the movement of air from inside a property to outside from a loft fitted unit. As the PIV is situated in the loft it ensures there is no condensation in the loft and the continuous circulation of air eliminates condensation throughout.
