The Wraptite® external air barrier system from the A. Proctor Group is achieving an efficient airtightness solution at two new-build extensions to the Connolly Hospital in Dublin. The project consisted of two phases, a new laboratory building in phase one, with a brand new accident & emergency facility constructed in phase two.
The Wraptite system is the only self-adhering vapour permeable air barrier certified by the BBA. It combines the critical properties of vapour permeability and airtightness in one selfadhering membrane. This approach saves on both the labour and material costs associated with achieving the energy efficiency demands in buildings.
Air leakage through cracks, gaps, holes and improperly sealed elements such as doors and windows can cause a significant reduction in the performance of even thermally insulated envelopes, in some cases reducing their effectiveness by up to 70%.
