Steel windows retain profile of listed
city school
Aluminium sash windows replaced in order to incorporate new standards of sound and heat loss insulation.
In 1967 a new building for St Paul's Cathedral Choir School was opened within the cathedral grounds and the choir boys were spared their daily march through ever-increasing London traffic The sound insulation being particularly important to the Choir School, all the new windows assist in reducing the traffic and building works noise in the area

Restoration Of Suspended Ceilings Saves Costs
Given the high cost to have suspended ceilings installed it makes sense to restore them when they become discoloured.
Glazed System For The Stars
Alco Beldan have completed an installation at a recently renovated property in North London which used to be the home of the golden couple Lulu and the late Maurice Gibb.
The planning authority is the City of London, which consulted the Twentieth Century Society and English Heritage as part of their consideration of the application to replace the windows.
The window replacement contract was subject to strict planning constraints to ensure retention of the school's original look.
The plan was to fit double-glazed windows to reduce noise and improve thermal insulation; aluminium frames were not chosen as the profiles and sizes of those sections were too large to comply with the visual elevational restraints and internal layout restraints.
Steel frames were able to retain the fine lines of the original design, so from their range of products Steel Window Service and Supplies recommended the W40 unit.
To retain the uncluttered building profile created by the sliding sash windows - even when the windows are open - open-out casements were not permitted by City of London Planning Authority.
The three panes of the tall, narrow windows were reproduced in the replacement windows but this time with both the bottom and middle sections fixed.
The top pane was bottom hung and opened inwards with the use of an operating pole.
The appearance of the original aluminium frames was mimicked using a metallic polyester powder coating and the bottom pane of glass remained opaque.
Special fixing lugs were used to secure the frames into the building's internal structure which required removing the plaster and replacement of damp proof membranes.
"We are delighted with the new windows," says Nikki Lovell the School Bursar.
"The building is much quieter and warmer, and we don't have to worry about the children's fingers anymore in the worn-out sash devices.
"After fixing the windows, Steel Window Service and Supplies redecorated the rooms and were extremely considerate of teachers and pupils, as the school remained open for the duration of the work.".
