Within the internal and external glazing package, a laminated pleated chiffon design was specified across all areas but in order to be installed the actual specification of the glass manufactured varied depending on its area:

Internal Glazing
Twenty four panels of fabric laminated between layers of 5mm toughened low iron glass.

Internal fire rated double glazed units
Twenty four fire-rated double glazed units (DGU's). DGU's made up of fabric laminated between layers of 5mm toughened low iron glass, a steel spacer bar, then 60/0 fire rated clear toughened glass on the other side.

Insulated external double glazed units
Sixty external glazing DGU's. Outer face of DGU's manufactured from two layers of 5mm toughened low-iron glass, laminated with a fabric interlayer. The front face is also very softly sandblasted to create a matte finish and reduce reflections. Behind this is 16mm black spacer and then inner layer of 6mm silvered toughened float glass, with the cavity space argon filled. This DGU is then bonded to 100mm thick mineral wool insulation and the insulation is covered with aluminium foil for protection.
