The need for proven fire protection for self-supporting mains gas risers which extended up through 21 storeys led to Promat’s PROMATECT®-L500 board being selected for a residential refurbishment project in Camden, London. Three multi-storey housing blocks on the Ampthill Estate have now been protected by the PROMATECT®-L500 fire protection board, which was used to create a bespoke solution tailored to the individual needs of this project.

“This was a refurbishment job which had some fairly specific requirements that we had to meet,” says Promat Area Sales Manager, Phil Telford. “The Fire Officers involved were insistent that the main gas riser feeding each block of flats was either moved to the exterior of the building, or was separated from the main shaft in which it was located. The latter option was taken, and it was decided to compartmentalise the gas mains with a gas-tight, enclosure that would provide 120 minutes of fire resistance.”

Promat devised the fire compartment system for the gas mains, which was constructed from PROMATECT®-L500 boards provided by SIG Technical Insulation Barking and installed by Fire Delay Contractors Ltd.

SIG Distribution ensured that everything was in place ready to be delivered when Fire Delay Contractors Ltd requested the material. There were quite a few deliveries that were required next day when areas were made available on site. The team had to make sure the stock was held at the Barking branch and liaised with Fire Delay on a weekly basis so they could keep up with their requirements and make sure everything was in place.
