Product Description

Predominantly used as part of the British Gypsum FireCase structural steel encasement system, giving up to 180 minutes of fire protection.

Glasroc F firecase consists of gypsum incorporating a tissue of glass fibre immediately below the surface of the board. The core is reinforced with glass fibre rovings and paper pulp. Available in square edge only.

Non-combustible Glasroc F boards, developed using paper-free glass fibre technology, provide the basis for a range of steel encasement and specialist lining systems. These offer quick and simple installation, and measurable performance for maximum protection and safety. The high impact resistance and moisture tolerance properties of Glasroc F make it suitable for installation in semi-exposed areas before the building envelope is complete, saving cost and time on major projects. Glasroc F performance has enhanced moisture resistant performance, now reaching H1 moisture absorption.

The smooth face of Glasroc F firecase can be plastered with either Thistle Board Finish, Thistle Multi-Finish or Thistle Durafinish. There should be a minimum of delay between completion of the lining and the commencement of plastering.


Gyproc jointing materials produce durable joint reinforcement and a smooth, continuous, crack-resistant surface ready for priming and final decoration. Use Gyproc Joint Cement for jointing Glasroc F firecase.


After the joint treatment has dried, decoration, including any decorator’s preparatory work, should follow with the minimum delay.

Gyproc Joint Cement is trowel applied to the joint and Gyproc Joint Tape bedded in. Alternatively Thistle ProTape FT50 is applied over the joint and a coat of Gyproc Joint Cement is trowel applied. The joint treatment is allowed to dry and lightly sanded to remove any high spots. For internal angles the use of Gyproc Joint Tape is preferable to Thistle ProTape FT50. Its crease makes it easier to achieve a neat, straight joint with higher cracking resistance.

For external angles, Gyproc Corner Tape, can be used, bedded in Gyproc Joint Cement. A second coat of Gyproc Joint Cement is trowel applied and feathered out to about 200mm width on each side on the joint. The joint treatment is allowed to dry and lightly sanded. Gyproc Metal Drywall Angle Bead can be used but Gyproc Joint Filler must be used on the first two coats.

A third coat of Gyproc Joint Cement may be necessary, applied as the second coat and slightly wider e.g. where boards are fixed with any steps, gaps or minor damage. When the final application has dried and been sanded smooth, the surface is ready for decoration.
