University of Birmingham

A University of Firsts

Client: Birmingham University

To make the University of Birmingham a warmer and more comfortable learning space, the primary windows were initially removed, stripped, repainted and re-glazed like for like. Although restored, the single glazed units were still inefficient, so Selectaglaze were specified by Associate Architects to provide a solution with its secondary glazing. The design specification was very demanding, with the secondary glazing required to; provide noise reduction of 45 – 48dB; seal the envelope of the building achieving air leakage of less than 5m3/m2/hr (half that of the current building regulations); provide protection from falling at the edge of the new floors and improve the thermal retention by lowering the U-value to 1.9w/m2K. Over 200 units were installed with varying designs and styles, many of which were curved to suit the building. All of the secondary glazed units are bespoke to the window openings ensuring the tightest fit and match sight lines wherever possible. All units are fully assembled in the factory allowing for rapid installation in order to minimise disruption.
