More than 50 bespoke casement windows and doors have been manufactured by George Barnsdale & Sons Ltd for the refurbishment of a five-storey London office building.

CCS (Developments) Ltd turned to British Woodworking Federation member George Barnsdale, of Spalding, to solve the challenging Flag House revamp, which included the need to respect the original fenestration.

George Barnsdale carried out a full survey of all openings in the brick built elevations before fabricating its windows and doors.

Working under the recently revised Part L (conservation of fuel and power) of the Building Regulations, the company made and installed all doors and windows with 24mm IG glazing units containing low-E coated glass. The windows were factory finished using a vapour permeable woodstain.

The contract included C2 flush casement windows in a range of sizes with side hung and top hung opening lights, while the main entrance screen was assembled from two separate units installed either side of the double doors.
