Crittall windows for Iconic London landmark

The Old Building at the prestigious School of Oriental and African Studies in London has a new appearance, thanks to a replacement window scheme involving Crittall Windows. The original building on Russell Square was designed in the late 1930s by Charles Henry Holden, best known for his designs of underground stations.

Being Grade II listed, the upgrade specified like for like replacement - and in this case, this involved the removal of existing Crittall steel profiles from their decaying timber subframes and the installation of new high performance steel Corporate W20 units.

The scheme is part of an on-going plan to upgrade the SOAS campus, with the new Crittall windows serving a dual purpose; maintaining the overall visual appearance of the architecture and significantly improving the thermal performance. As the doors and windows span five storeys, new double glazed contemporary windows that comply with stringent conservation and environmental requirements will make a noticeable difference on heat gain and maintenance costs. In addition, they provide a timeless aesthetic quality to the architecture, without overshadowing the prominence of the structure itself.

A selection of side hung and open out vents were installed, together with horizontal and vertical pivots, louvres and fixed lights, all in a uniform RAL cream colour to heighten the visual appeal.

Architects Kendall Kingscott were responsible for the project with Overbury appointed as main contractors. The work was completed on time and to schedule, with the Crittall installers managing the work so smoothly and deftly that they were awarded Overbury's contractor of the month award for their 'flexible approach and professionalism '.
