Linear Gap Seal Block CLGB

PFC Corofil Linear Gap Seal Block is a stone wool block installed in the trapezoidal profile of a composite profile deck at the head of flexible and rigid wall constructions and above a steel beam protected with a gypsumbased cladding system.

Tested utilising the principles of EN1366-4, PFC Corofil Linear Gap Seal Blocks will provide up to 120 minutes of fire integrity and insulation performance.

The product is supplied pre-cut to suit the profile of the composite deck in which it is to be installed. The fire-stopping blocks can be installed in composite decks with profiles up to 210mm, to the depth of the wall head or beam*, a minimum of 100mm deep. When ordering please supply the following information:

  • Required fire rating
  • Profile sheet reference or exact profile dimensions
  • Large or small profile to be filled
  • Individual blocks or linear metre run of corrugations
  • Quantity required (individual blocks or linear metres)

Where should you use a PFC Corofil Fire-Stopping Block?

PFC Corofil fire-stopping blocks are designed and tested to close off the trapezoidal void of a composite profile deck at the head of a flexible or rigid wall and above a steel beam* protected with a gypsum based cladding system.

The fire-stopping blocks for a flexible wall should be installed flush with the outer face of the plasterboard on both sides. For a rigid wall the fire-stopping block should be a minimum 100mm deep and installed centrally within the wall above a separate Linear Gap Seal Strip to a maximum profile of 210mm and a maximum linear gap width of 150mm. The block above the steel beam* should finish flush with both outer faces of the gypsum based cladding system.
