Main Focus
The main focus of the project, after change of use had been
designated for the adjacent factory, was to upgrade the fire
protection on the separating wall to a full 30 minutes, without
causing any disruption of production of fan casings for Rolls Royce
engines destined to power Boeing and Airbus planes, with likely
attendant costs of £10M per week.
Challenge
The challenge arose because the lining system could only be
built from one side, with no disruption to production, utilising a
clean, dust-free installation system, which would also be easy to
maintain in terms of repair and repainting.
Solution
The solution was to use the GypLyner IWL system with 60mm Gypframe 'I'
Studs, in front of the existing profiled wall panel, but tied back
to it at mid height. Gypframe GFS1 Fixing Strap was installed
behind horizontal board joints. All board joints were treated with
intumescent mastic and the joints were covered using Gyproc Joint
Trims. Each 15mm Gyproc FireLine board was thus fixed and trims
fitted in one continuous process, ensuring a speedy and clean
installation.
25mm Glasroc FireCase S was
also used at columns and head fixings for extra protection, along
with ease of fixing back to the steel work.
This solution was eminently suitable for the factory owners, their
insurance company and building control.
