    Product Description:

    Fire Protection for Structural Steel Columns and Beams


    Knauf Fireboard is a glass fibre reinforced gypsum board specially developed for high performance lining and encasement, providing up to two hours of fire protection.

    Knauf Fireboard has a high quality white smooth surface finish which is ideal for most paint finishes, can be plastered directly, or left undecorated.

    Knauf Fireboard Gripper Screws are gold passivated screws with spoon tips and ‘hi-low’ threads.

    Knauf Uniflott is a specially formulated compound for jointing and filling Knauf Fireboard to help maintain the performance of the system. Knauf Uniflott is available from Knauf Drywall through Encon.


    Knauf Fireboard is suitable for the encasement of structural steelwork to provide up to two hours of fire protection.

    Knauf Fireboard is used to form a frameless encasement. Knauf Fireboard has been specially developed to accept direct edge fixings. Casings consist of Knauf Fireboard screwed or stapled to itself at abutting corners.

    For steelwork encased on all four sides, Knauf Fireboard is fixed at each corner directly through the material, independent of the column or beam. For partial encasement, involving wall or ceiling abutments, Knauf Fireboard is fixed to light gauge steel angles.

    Knauf Insulation recommend the use of Knauf Fireboard Gripper Screws, essential for fast construction, solid fixing and tight edge joints.
