Concept Linear Firestops are designed to prevent the passage of fire at the point where walls meet concrete soffits and profiled metal decking. The Linear Firestop strip can also be used as an expansion joint in masonry walls.

Concept Linear Firestop Strips are supplied 1200mm long and factory cut to suit the aperture to be filled. Concept Firestop Blocks are supplied to suit the trapezoidal profile of the metal decking specification.

The mineral wool used in the production of Concept Linear Firestop strips and blocks achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1.

The product range has been independently tested adopting procedures and criteria from BS476 : part 20 : (1987)

CCL Linear Firestop Strips and Trapezoidal Fire Blocks are designed to be installed using the correct amount of compression as the only method of holding the barriers in place. No mechanical fixings are required. The insulation must be compressed and must fit tightly and completely both in height and width. All joints must be tightly butted.

CCL Linear Firestop Strips Trapezoidal Fire Blocks should be compression fitted with any joints tightly butted. Ensure surfaces are clean, dry, and free from dirt, or any other contaminants. Ensure the opening to be filled is suitable for the product being installed.  Measure the dimensions of the Firestop Strip and Fire Block to ensure that it is for the correct profile and length to suit the fire performance required. Compress the Linear Firestop Strip and push into the linear gap at the head of the wall ensuring it is central within the wall. Compress the Trapezoidal Fire Block and push into the profile ensuring it finishes flush with the outer face of the Linear Firestop Strip. Where necessary, small gaps and uneven surfaces may be filled with intumescent mastic.
