New houses are being built with better construction methods and are more airtight, which can lead to condensation dampness and poor indoor air quality if adequate ventilation is not provided. The drive towards more energy efficient homes through building fabric combined with the condensation and pollutants generated from every day activities such as washing, cooking, smoking and cleaning can create poor indoor air quality that is damaging the health of the occupants and the building fabric.

New homes are not alone in suffering from poor ventilation. Many older homes are inadequately ventilated, and often the steps we take to better insulate older homes through installing new windows and adding loft insulation can further decrease the natural ventilation.  Washing, cooking, cleaning and drying clothes indoors all contribute to the creation of condensation and pollutants in the air.

The modern ventilation units provide whole home ventilation based on the popular Positive Input Ventilation principle. Essentially, the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. To achieve this, the unit is mounted in the loft space or in the kitchen or hallway, drawing air through the filters and inputting it into the property.

A property installed unit will ensure that old, contaminated and moisture-laden air in your home is continuously diluted, displaced and replaced with good quality, fresh air. The result is an environment in which condensation dampness cannot exist, and where allergens and pollutants are kept to a minimum.

Both PIV ranges are quick, cost-effective and easy to install, making them an ideal solution for both new build and RMI projects.
