Doors & Windows

New steel windows provide a warm view of London


Providing views across the River Thames towards The Shard and other London landmarks, the windows at President’s Quay, in St Katherine’s Way near Tower Bridge, have suffered from significant exposure to the weather. Residents in a number of flats were consequently keen to have replacement steel windows and doors installed that had a similar aesthetic but achieved improved thermal efficiency.

Steel Window Association member, NSB Casements, were therefore awarded a contract to carry out the works.

President’s Quay is an historic docklands warehouse building which was converted to, fifteen one-, two- and three- bedroom flats many years ago. The replacement steel windows and doors at that time were of W20 style and single glazed.

Within the flats, each of the rooms either incorporated a double door or side hung vent windows. The new windows and doors, manufactured by NSB Casements, match the original design but are fabricated from W40 system profiles and have currently been installed in four flats.

As the most modern version of the traditional W20 steel window, the W40 system achieves continuity of style by offering similar attributes in terms of slenderness and light transmission. Triple glazing is an option, although warm-edge spacer bars, gas filling and other enhancements enable Part L of the Building Regulations to be complied with in new build, for most applications, when specifying double glazed units.

All the steel windows and doors manufactured for President’s Quay were hot-dipped, galvanised and finished with a white powder coating to provide and almost maintenance-free life span. A multipoint locking system was added for maximum security – W40 system installations can be supplied to Secured by Design standard. This design not only dramatically improves the U-value against single glazed windows but, with the multipoint locking system, draughts are practically eliminated.
