However due to improved workmanship,…

Ventilation in retrofit projects is often one of the most overlooked considerations.  Yet ignoring ventilation is high risk, both in terms of occupant health and minimising moisture risk to the building fabric. Most retrofits, by their very nature, will automatically have a dramatic reduction effect on air leakage. However, it can be quite confusing to work out how best to ventilate - natural, mechanical - centralised or decentralised. A number of factors will dictate the most appropriate strategy,…
