Steel window profiles from Crittall Windows have been used at University College London. Specified to meet planning requirements and complement surrounding buildings, large pieces of glass were installed without transomes and mullions alongside fewer sealed joints. A low co-efficient of expansion reduces thermal movement and the risk of perimeter sealant failure.
Combining timber on the internal window face and aluminium on the outer, Crittall's Composite range of windows meets performance requirements in commercial and residential applications. It provides thermal and acoustic performance through the high thermal mass of the timber element and 28mm double-glazed units utilising low 'E' glass and gas filled cavities.
All the windows in the new Soho Hotel in London have been supplied by Crittall Windows using the Corporate W20 and 2000 ranges. In total, 150 windows were supplied, with small panes and curved heads. In addition, the front entrance doors were designed using the company's cold formed sections.
Some 50 colours are available with the Duralife polyester powder coating system from Crittall. This in-house factory applied process, which involves electrostatically sprayed application of an epoxy-free polyester powder onto previously galvanised windows which are then stoved. This is designed to ensure that the steel windows and doors have a permanent, aesthetically pleasing protection.
Steel windows from Crittall have been incorporated into the design ofBeaufort Court, the former Ovaltine Egg Farm in Hertfordshire. Under the planning guidelines for the site the views of the outside of the building had to remain largely unchanged. The installation of the 90 steel profiles followed the planning considerations and matched the steel courtyard enclosure.
