Airtightness and weather sealing were the priorities when it came to installing the windows at the new headquarters of Moneypenny, the UK's leading telephone answering service.
With this in mind, tremco illbruck was asked to provide a detail for the perimeter of the windows and supplied three products that helped ensure the performance of the £15m project surpassed expectations.
Designed by AEW Architects, the 91,000sq.ft, three storey office complex in Wrexham, North Wales, has large floor-to-ceiling Velfac windows that provide the 500 employees with far-reaching views of the surrounding countryside. 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 3 m³/h.m² at 50 Pa but, thanks to careful detailing and the use of illbruck products, an impressive 2.88 m³/h.m² at 50 Pa was achieved.
illbruck products were chosen due to their ease of use and compatibility and the company worked closely with both Pochin's, the main contractor, and the window installer. The service comprised 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, taking the full force of wind and rain, so illbruck SP525 Frame and Façade Sealant and Adhesive was used at the joints.
Simon Taylor, site manager, Pochin's, comments: "tremco illbruck was brilliant. The products and the help and follow-up we got on site was excellent and we've had no problems since."
