Roofshield, the unique vapour and air permeable pitched roof underlay
has been chosen for a multi-million-pound project set to transform the
transport links across Northern Ireland.
The North West Transport Hub is an impressive £27 million redevelopment of the Waterside train station in Derry to create a multimodal transport facility, which includes a brand new train terminus, bus stands, park-and-ride facility, passenger waiting area, retail units and community space. The new hub will provide for up to 1100 new local and cross border bus and connecting rail services.
Translink commissioned Farrans Construction to manage the project alongside railway engineers Rhomberg Sersa JV. Specialist roofing contractors D. Harkin & Co. Roofing of Derry was appointed to carry out all roofing works and selected the Roofshield membrane from the A. Proctor Group to ensure the highest level of protection.
Danny Harkin Managing Director of D. Harkin & Co explains the reasons for the selection of Roofshield. “We chose Roofshield because of its superior air permeability, which removes the need for any additional ventilation and assures comprehensive protection for the new hub facility.”
The use of Roofshield can lead to savings in labour and material costs, due to no VCL being required, and its high-performance air permeability means that the roof space has similar air changes to that of a roof using traditional eaves/ridge ventilation.
Many vapour and air permeable underlays use an airtight VP film layer to achieve their performance, whilst Roofshield’s patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible.
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.
