State of the art ductwork system for new state of the art cancer clinic

The award winning Flamebar BW11 fire-rated ductwork system, manufactured and installed by Fire Protection Ltd (FPL), has been chosen for the new £35.2m London Cancer Clinic located in Harley Street, London. When complete, the facility will be one of the most advanced cancer research and treatment centres in Europe.

Finding sufficient space for the storage of construction materials on site always causes a quandary in London and the problem again presented its own set of difficulties on this project.

Versatile Flamebar BW11 is, however, well-suited to this type of installation and to help combat the issue, the ductwork was delivered in modules; thus dividing complex elements into manageable sections. As well as reducing clutter on site, the arrangement also contributed toward lowering costs and improving site safety.

Flamebar BW11 is constructed from galvanised sheet steel, sprayed with a specially formulated water-based fire protective compound. The compound contains selected mineral filters in a low permeability elastomeric binder and is applied at a thickness of approximately 1mm. Its unique design of low density and high durability allows it to accommodate induced stress arising from extreme conditions including climatic moisture, structural loading and the effect of thermal-shock during a fire.

The system has been successfully tested for international use, under cellulosic fire conditions, to give in excess of four hours fire resistance in the event of a fire. It is accredited by the Building Research Establishment (BRE) to BS 476 Part 24 (1987) and also classified by UL to ISO 6944 (1985) up to a temperature of 1133°C. In addition, it is accredited by FIRAS and certified to LPS1531 (approved passive installer).

To assist clients and specifiers and to ensure quality installations, FPL engineers are able to call upon years of experience in order to, for example, calculate the support system required to cope with transportation, or the reduced strength of steel in a fire installation, thus providing a fire-rated ductwork system that will perform correctly in the event of a fire.

Flamebar BW11 has been specified for such prestigious buildings as Heathrow Terminal 5, the Swiss Re 'Gherkin' in the City of London, the Houses of Parliament and the Hong Kong & Shanghai Bank's world headquarters at Canary Wharf. In order to meet increasing demand for the system, FPL has recently opened an additional manufacturing facility in Polegate, East Sussex.
