Former home to the BBC, and now luxury office space, Bush House was renovated as part of a two-year, £60 million project back in 2012.
Part of the unique appeal of secondary glazing, is the ability to bring modern thermal and acoustic insulation to buildings, whilst remaining respectful to the original design aesthetics. In this instance Granada worked with ISG and JRA to develop a completely new product — the odd leg horizontal sliding sash, with 6.4mm low ‘e’ laminate glass. The unique ‘odd leg’ build out detail, provided ISG with a more appropriate and secure flush aluminium alloy sub-frame detailing.
