Unitised curtain
wall facade
The main envelope installation was achieved using a pre-fabricated and pre-glazed unitised form of
construction and without the need for costly scaffolding. Elements were installed using our own fl oor
cranes and the “Table Method” as shown below.
This method allows facade elements to be passed over the top of the handrails and installed with the
slab edge protection remaining in place providing a safety barrier for our operatives and others on site.
The bespoke curtain wall elements, typically 1.5 m wide by 3.905 m high, were manufactured off-site at
our Head Quarters in Arnstorf, Germany and delivered to site by road.
The vertical feature fi ns, where required, were fi tted to the elements before installation.

Unitised
Facade
to Offi ce
Areas
The main envelope is comprised
of pre-fabricated and pre-glazed
curtain wall elements with a natural
anodised fi nish. The system is a
structural silicone glazed (SSG)
design which incorporates a small
sub-frame to aid re-glazing. Vertical
feature fi ns have an aluminium
perimeter frame that has a double
glazing unit with Kapilux capillary
tube type insulation inside. This
material is also used in parts of the
vision glazing to add visual interest.

Technical details
Facade performance test to CWCT sequence B
- Watertightness static and dynamic: 600 Pa
- Air permeability: 600 Pa
- Thermal insulation curtain wall (typical): U cw 1.4 to 1.6 W/m 2 K
- Thermal insulation glazing: U g 1.1 W/m 2 K
- Solar shading / glazing g value: 0.33
- Light transmission: 60 %

Typical elevation and
section details of glazing
system and fi ns
The facade was tested to CWCT sequence B to 600 Pa, including dynamic aero engine test. Double glazed
units to the vision areas had a combined high performance solar control and low-e coating to give high
thermal insulation and high solar shading yet allow high light transmission through the glazing.
