Mould is an all-too-common problem in buildings throughout Ireland, and it poses a significant risk to both the structural integrity of the building and the quality of the air inside. To prevent the growth of dangerous mould spores, it is absolutely essential that appropriate measures are taken to focus on improving indoor air quality (IAQ).
Positive Input Ventilation (PIV) creates a healthy environment by pumping and circulating fresh filtered air into a house, forcing stale air out of gaps and cracks in the building fabric.
The PIV unit is installed in the loft area, and a distribution diffuser is mounted in the ceiling in the room below. Continual supply and slight positive pressure result in the air in the building being continually diluted, displaced, and replaced. They also significantly improve indoor air quality by removing pollutants like carbon dioxide. According to the World Health Organization, air pollution disproportionately affects women, newborns and young children. They also keep out external contaminants such as traffic fumes and pollen. PIV systems force internal humid air that carries pollutants outside whilst simultaneously keeping pollutants outside from entering the building. This is due to the property’s positive pressurisation. This creates a barrier that prevents external pollutants from entering the building while forcing internal pollutants out.
