Moneypenny’s bond detail
Airtightness and weather sealing were the priorities when it came to installing the windows at the new headquarters of telephone answering service Moneypenny.
Tremco Illbruck provided a detail for the perimeter of the windows and supplied three products that helped ensure the performance of the £15m project met requirements.
Designed by AEW Architects, the 91,000ft2, three storey office complex in Wrexham, North Wales, has large floor-to-ceiling Velfac windows. These were installed within an aluminium rain screen, flush with the steel structural framing system. With the primary line of airtightness at the outer cement particleboard, the aim was to achieve 3m³/h/m² at 50Pa but, thanks to careful detailing and the use of Illbruck products, 2.88m³/h/m² at 50Pa was achieved.
The service included site visits and toolbox talks to site operatives. The installation included illbruck ME501 Duo Window Membrane HD wrapped around the steel SFS and bonded centrally. Illbruck ME315 Total Protection Tape was then used to bond the edges of the membrane to the CP board, creating an airseal with the SFS.
The building is in an exposed situation, so Illbruck SP525 Frame and Facade Sealant and Adhesive was used at the joints.
