The inherent strength and slim sightlines characteristic of W20 steel sections have enabled a member of the Steel Window Association to create a large screen with two sets of double doors, forming the entire gable end to a North London period property’s new extension: elegantly linking the expanded kitchen dining area with the rear garden.
Steel Window Service & Supplies, based in Oxford Road, London N4, carried out the design, manufacture and installation of the multilight screen, which measures 4,484mm x 3,427mm high. The frames are hot dip galvanised prior to being finished in a polyester powder paint system.
The highly experienced SWA member worked with the client to maximise the practicality of the screen as a connection with the outside space, finessing the position of the mullions so that the outer leaves to the two doorsets will fold back 1800, while the central ones open to 900. Both doorsets feature locking handles with concealed bolts.
Commenting on his selection of the W20 solution for the project, the owner of the property Ian Forshew, said: “There is no doubt that the steel windows are in keeping with the architectural style of the property; and I was impressed with Steel Window Service & Supplies so I basically went with their recommendation.”
W20 and W40 steel windows and doors meet the requirements of the Building Regulations in new-build as well as refurbishment situations. In the case of Ian Forshew’s residential extension, the standard Steel Window Association specification sealed units have a 4-6-4 make up, with toughened, low-E coated glass for the inner leaf. Combined with a Krypton filled cavity, this provides an overall frame U-value of 1.8 W/m2 K, while the excellent light transmission characteristics of the steel framed system maximise use of natural daylight as well as solar gain in the winter.
The members of the Steel Window Association are able to provide a comprehensive response to customers from across the commercial, residential and local authority sectors, including for the replica refurbishment of old style steel and other metal fenestration.
