Description

A structural steel, frameless cladding system that offers up to 2 hours fire protection to universal column and beam sections and many joist sections, portal frames and castellated beam sections. It can be used in any type of building where an encasement is required to structural steelwork.

The Glasroc FireCase s lining provides a smooth, robust surface, and can be left unfinished if required. The boards, however, can be plastered or painted and the surface can be tiled using conventional tile adhesive without pre-treatment.

Partitions and wall linings can be fixed directly to the Glasroc FireCase s cladding as long as:

  • The fire resistance requirement of the partition is 60 minutes or less.
  • There are no special requirements for pressure resistance, e.g. around lift shafts.
  • There are no special loading requirements, i.e. Heavy Duty or Severe Duty as defined in recognised partition performance specifications (e.g. BS 5234).

Where these criteria are not met, the partition framing must be suitably fixed to the structural steel section through the Glasroc FireCase s cladding. Where the partition abuts the web of the structural steel, a suitable steel nogging must be provided.

Where steel section web dimensions exceed 600 mm, additional support may be required for the cladding – contact the British Gypsum Drywall Academy Advice Centre for guidance.

Not suitable for use in areas subjected to continuous damp or humid conditions.

Product Options

Extent of protection to structural members:

  • Four-sided protection to steel columns: Cladding is commenced from the base of the column. Boards are positioned and staple-fixed board-to-board using a Gyproc Impulse Staple Gun (or similar), or alternatively, using Gyproc Firecase Screws of appropriate length, at 150 mm centres. Board joints on adjacent sides are staggered by a minimum 600 mm. For double layer linings, board joints are staggered between layers by a minimum 300 mm.
  • Three-sided protection to steel columns incorporating steel angles: Gypframe GA1 Steel Angle is fixed to the wall both sides of the column, at maximum 600 mm centres. Additional steel angles are incorporated where the column flange is at right angles to the wall structure. Boards are positioned and screw-fixed to the steel angles at 150 mm centres. Board-to-board fixings are made by staples using a Gyproc Impulse Staple Gun (or similar), or alternatively, using Gyproc Firecase Screws of appropriate length, at 150 mm centres. For double layer linings, board joints are staggered between layers by a minimum 300 mm.
  • Three-sided protection to steel beams incorporating steel angles: Gypframe GA1 Steel Angle is fixed to the wall both sides of the column, at maximum 600 mm centres. Additional steel angles are incorporated where the column flange is at right angles to the wall structure. Boards are positioned and screw-fixed to the steel angles at 150 mm centres. Board-to-board fixings are made by staples using a Gyproc Impulse Staple Gun (or similar), or alternatively, using Gyproc Firecase Screws of appropriate length, at 150 mm centres. For double layer linings, board joints are staggered between layers by a minimum 300 mm. For single layer encasements, fascia board joints are backed with Glasroc FireCase s strips, cut to a minimum 60 mm width and stapled or screw-fixed behind fascia board ends so as to half-lap the joints.
  • Three-sided protection to steel columns and beams incorporating Glasroc FireCase s soldiers to support single layer linings: Glasroc FireCase s soldiers are pre-cut to fit neatly into the steel section. The soldiers are located into both sides of the section at 1200 mm maximum centres as boarding progresses. At fascia board joints, two soldiers are fitted side by side so that each one finishes flush with the board end. Cladding is fixed to each joint soldier and also any intermediate soldiers using three staples, fixed using a Gyproc Impulse Staple Gun (or similar), or alternatively, using three Gyproc Firecase Screws of appropriate length. Boarding is continued as previously, staggering board joints.
