Why Ventilate?

Ventilating our homes creates and maintains the air quality we need to ensure that a healthy indoor living environment exists every day.

Many of us are not aware that the well-intentioned energy efficiencies we introduce to our homes often negatively affect the air quality which can then compromise our health. In winter, the issue of poor air quality is compounded further in the simple act of taking every possible measure to retain the precious heat we generate in an effort to keep the cold at bay.

Insulation solutions make homes easier to heat, however, this can affect the good ventilation essential for better air quality, no matter what the age of your home.

Over a year a family can produce as much as 3,500 litres of moisture in the air inside their home and damp homes are much harder to heat than dry ones.
