For this insulation extraction project, we removed fibreglass insulation from this cavity wall. It was a bungalow and within 3 days of getting the cavity wall re-filled the difference in the heat staying in the house was already being felt. There was mould in the bedroom and bathroom at the back of the house. The Waterford based client (Norwood, Waterford) believed it was due to a lack of sunshine but the actual reason was due to the fibreglass retaining rain water that had soaked into the wall.
