In Britain's largest PFI project to date, irius fasteners from SFS intec were chosen throughout for the roof construction of the new Government Communications Headquarters (GCHQ) in Cheltenham.
Working in partnership with Prater Roofing Ltd and Corus Building Systems, SFS intec supplied fasteners for the doughnut shaped GCHQ main building covered by 12,000 square metres of Kalzip aluminium standing seam roofing Due to the toroidal shape of the main facility, SFS intec worked closely with Prater to clarify the fixing detail on the complex and unique roof build

SFS irius Goes Celestia
SFS intec's Construction Fasteners division has launched a range of irius-coated fasteners with the exciting Celestia by Corus metallic finishes for maximum aesthetic impact.
The main campus comprises three radiused buildings covered by standard and tapered Kalzip sheets.
The connections between the three buildings are over-roofed with three "petals" comprising 70m long (eave to eave).
Kalzip roofing supported above the main roof with glazed side-wall panels.
These "petals" complete the circle and are also carried over the internal and external entrances to the three buildings.
The main roof build up comprises a steel liner sheet fixed to purlins with SFS intec SD3 fasteners on top of which is laid the vapour control layer fastened down with bulbtite rivets.
The Rockwool insulation layer sits above this with 80mm steel clips incorporating a thermal barrier pad fixed with SFS intec SX2 fasteners to top hat bars fixed to the steel liner.
The Kalzip stucco embossed aluminium weather layer is clipped and zipped as a standing seam over the 80mm up stand of the steel clips.
To complement the aesthetic design of the buildings, the eaves to the petals have a bull nose profile hiding internal guttering with aluminium perglimmer finish soffits where the eaves overhang.
SFS intec torx drive SX3 low profile fasteners were used for the secret fix detail on the eaves.
In addition to the main facility, fasteners from SFS intec were also used on six separate service buildings on the site known as the "String of Pearls".
The roof build up here was similar to that of the main building.
The new GCHQ complex replaces 50 buildings spread over two sites with one efficient campus that will accommodate over 4,000 employees.
The building will be maintained by a consortium of Carillion, Group 4 and BT for the next 30 years.
