A new development of student accommodation in the Scottish capital, designed by Richard Murphy Architects, is nearing completion, with products from the range of tremco illbruck being employed to install and seal the high performance, composite window systems which project from the elevations in steel frames.
Holyrood South, constructed by Balfour Beatty, stands by Holyrood Road in Edinburgh's famous Old Town. It offers a total of 249 en-suite student bedrooms arranged in groups for four, five or six persons with the living accommodation gaining natural daylight through Velfac windows which are being fitted by specialist installer, Keyes Brothers.
Both the South block and the larger Holyrood North have been designed to achieve a BREEAM Excellent rating with window energy performance contributing significantly to the thermal integrity of the building envelope. Accordingly, TP450 has been supplied to Keyes Brothers for weather-sealing the steel window sub-frame units to the precast concrete wall sections with ME501 making the air seal in the same area. Additionally, TP600 was utilised to seal around aluminium flashings where they cover the perimeter to the Velfac windows.
Director of Keyes Brothers, Colin Keyes commented: "As an approved installer of Velfac windows, we have plenty of experience in working on projects across the education, commercial, residential and other sectors where the designers are targeting very high standards of airtightness as well as overall energy performance. Tremco's products have helped us achieve these goals.
"Products like illbruck's TP450 TP600 and Duo HD membrane are simple to apply and offer very reliable performance while the manufacturer always provides good technical support where it is required."
Also employed by the contractors was SP525 which was chosen for its advanced polymer technology and achievement of a long lasting, low modulus seal able to form joints subject to significant movement characteristics.
