The main focus of retrofit is to improve the thermal performance of the house, manage moisture and improve air quality. The most complex areas are around junctions, where if not property insulated they can become cold bridges. These areas then lose heat and cause condensation, where mould can grow. Our client project managed the construction works himself, to ensure that each specialist contractor met the necessary exacting requirements. We were impressed how much knowledge he gained through the process and his own research and has undoubtably made him an expert in the field. We love it when this happens on a project and someone shares our enthusiasm for sustainable construction.
