D. Harkin & Co from L’Derry used 1500m2 of Roofshield breather membrane for the recent roof refurbishment of the Lynn Library at Queens University in Belfast, which required major restoration of the insulation, membrane and slate finish.
Roofshield, supplied by the A. Proctor Group, is the best performing breather membrane on the market - it has the highest vapour permeability of any roofing membrane, and is also air permeable.
Due to the exceptional performance of the membrane, Roofshield remains fully BBA & NHBC compliant, in both warm & cold roofs, without the need for vents or a VCL. As a result of these savings, Roofshield demonstrates that increased performance need not increase cost.
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.
