QI Intufoam Linear Gap Seal is a versatile fire resistant linear gap seal intended to provide a fire stop seal for linear joints or at the junction of compartment floors and walls.
QI Intufoam Linear Gap Seal is a versatile fire resistant linear gap seal intended to provide a fire stop seal for linear joints or at the junction of compartment floors and walls. The compressible foam core accommodates different joint widths and a number of products are available providing different fi re ratings, in different gaps and orientations.
QI Intufoam Linear Gap Seal is manufactured from compressible foam, impregnated with fire retardant chemicals. The foam is then bonded to a graphite based intumescent material to form a composite seal. In the event of fire this expands to maintain the fire stop seal.
Features and benefits:
Standards and approvals:
The Intufoam system comprises of 1 metre lengths of a compressible foam core faced with a flexible intumescent material.
Different products within the range have a different number of layers of materials, making them suitable for different size gaps and applications.
Intufoam provides a reliable, easily installed fire seal to resist the passage of fire through linear gaps between non-combustible surfaces where an element of movement may be required.
The product is tested as defined in the relevant test reports and subsequent standard installation details, generally between concrete surfaces and QuelStop Fire Batt. Its suitability for use in conjunction with other substrates is not something we could comment on and instead should be determined or verified by a suitably qualified fire engineer.
Typical instances where the Intufoam may be considered are as follows:
Intufoam’s excellent compression and recovery allows movement within the product, the minimum and maximum gap sizes are set out in the table below. In the event of a fire, the product will react and become a carbonaceous char sealing the gap.
Installation:
Installation is by hand, the 1 metre lengths are simply compressed by hand and inserted in the linear gap where they will then expand holding themselves in place. Individual lengths should be installed with a tight butt joint, end to end. Where necessary to complete the length, Intufoam can be cut with a sharp knife or saw before inserting into the gap.
In some instances a single or double width seal is required and it may also be necessary to have the Intufoam set back from the exposed front face of the wall or floor, refer to the specific installation details for full details.
