Fix damp with positive input ventilation (PIV)
Either used in conjunction with, or as an alternative to, sub floor ventilation, positive input ventilation (PIV) is a whole home ventilation system. Positive input ventilation means that fresh air is drawn into the roof, filtered, and then diffused into your home at a continuous rate, encouraging the movement of air from inside to out.
A unit is mounted in the roof space and disperses fresh air at ceiling level. The units are fitted with an internal temperature sensor, so that air volume can be increased when the roof temperature is above a set level for passive heat recovery in the cooler months. If temperatures in the roof get too hot, standby mode kicks in to reduce air flow and prevent overheating your home. An option is also available for a unit that discharges into the central hallway – perfect for units, apartments and houses with no roof space.
