Located on the former site of the Royal Infirmary of Edinburgh in the heart of the city, Quartermile is a mixed use development comprising Grade A office buildings, retail and leisure space and luxury apartments. Alongside the new build apartment blocks lie the Lofts, two Grade B listed former hospital buildings which are being extensively refurbished and converted into further apartments by Quartermile Developments.
Originally built in the 19th century by noted architect Sidney Mitchell and being redesigned by Edinburgh based Comprehensive Design Architects, the impressive roof structures of these unique buildings required careful consideration of moisture management and condensation control. The scale and complexity of the turreted roofs, along with its historic appearance within a UN World Heritage Site made adding traditional ventilation to the roof highly undesirable, but also required a high performance and robust solution.
The architects did not have to travel far to find this solution however, as the Roofshield air and vapour permeable underlay specified is supplied by the A. Proctor Group. By combining the highest available vapour permeability with an air open structure which permits greater airflow than conventional ventilation, Roofshield ensures condensation problems are reduced or eliminated in even the most complex roof geometry.
Roofshield is fully BBA certified, and accepted for use without additional ridge ventilation by the NHBC.It also requires no taping to comply with BS5534:2014.
For any building to have an energy efficient, healthy, moisture free building envelope there is a clear need to manage the balance of Heat, Air and Moisture movement (HAMM) throughout the building’s life cycle from design, construction, completion and use.
