Definitions

  • This invention relates to fire-resistant barriers for preventing the spread of fire and smoke in roof spaces. More especially, the invention relates to fire-resistant barriers for preventing the spread of fire and smoke between the roof spaces of adjoining terraced buildings. The invention also has application for preventing the spread of fire and smoke in relatively large roof spaces.
  • GB-A- 2250933 discloses a fire barrier or curtain which comprises a sheet of woven glass fibrous cloth, typically of the thickness of 0.75mm which is coated on one side with an intumescent material and on its other side with a second coating of intumescent material or a layer of metallic foil, or a facing of neoprene or silicon.
  • GB-A-2297985 discloses a thermal insulating wall or door for use with cold rooms providing fire resistance.
  • the individual panels comprise slabs of polyurethane foam as thermal insulation faced with cast foamed magnesium oxychloride panels clad with sheet metal. Straightline paths between adjacent abutted panels are avoided by infills of high density mineral board and intumescent fillers.
  • GB-A-2318594 discloses a concealed cavity firestopping system comprising a preformed plastic sack which can be shaped to fill the voids or cavities common in the fabric of most buildings which unless firestopped will allow fire spread through those cavities.
  • the present invention sets out to provide a fire-resistant barrier which operates to prevent the spread of fire between adjoining roof spaces for an enhanced period of time, especially periods in excess of one hour.
  • a fire-resistant barrier for roof spaces comprising a fire curtain impregnated or coated with a quantity of an intumescent material, an intumescent-containing adhesive for adhering the fire curtain to one or more roof trusses or party walls of the roof space, a plurality of battens coated with or produced from an intumescent material for securing the fire curtain to roof trusses or party walls of the roof space, and pieces of fire retardant intumescent impregnated flexible foam or sponge, rockwool, ceramic felt or compressed glass wool for filling all gaps present between the fire curtain and the surrounding roof structure to seal the adjoining roof spaces one from the other.
  • a method of creating a fire barrier between neighbouring roof spaces lined with roofing felt comprising the steps of cutting through all roofing felt at the point at which the barrier is to be erected to expose all roofing tiles, battens of the roof structure in the area in which the barrier is to be erected, adhering to the exposed roof structure a fire curtain containing or coated with an intumescent material using an intumescent containing adhesive, attaching the sides of the fire curtain to the exposed roof structure using battens coated with or constructed essentially from an intumescent material, and filling all gaps present between the adjoining roof spaces with pieces of flexible cellular fire-retardant foam or sponge, or rockwool or ceramic felt or compressed glass wool to create an effective seal between the divided roof spaces.
  • the invention provides a method of erecting a fire barrier between a roof truss and party wall of a roof space lined with roofing felt, the method comprising the steps of cutting and/or removing all roofing felt between the party wall and the roof truss, adhering to the roof truss using an intumescent-containing adhesive a fire curtain impregnated or coated with an intumescent material extending the curtain towards and over the party wall and adhering the same to the party wall using an intumescent- containing adhesive whereby the curtain defines a fire barrier which extends across the full width of the roof space and along the entire roof interior surface between the truss and the party wall, and securing the curtain to the truss and/or the party wall with battens either coated with or essentially comprising intumescent material.
  • the fire curtain may include or be coated with a mixture of particular ceramic material, an intumescent substance and a binder.
  • the intumescent material may comprise exfoliating graphite and/or sodium silicate in granular and/or powder form.
  • the sheet containing the intumescent material may comprise a non-woven mat or sheet. The initial thickness of the sheet is preferably from 2 to 3mm and the sheet thickness when intumesced preferably exceeds 25mm.
  • a fire-retardant foam or sponge When a fire-retardant foam or sponge, it may be coated on at least one of its surfaces with a primer solution including a sealant and a flowable coating of fire-retardant material.
  • the primer solution operates to close the open pores of the coated surface of the rib and provides a bond to which the fire-retardant coating can adhere.
  • the primer solution may comprise an aqueous solution of an acrylic polymer, including ammonium polyphosphate.
  • the fire-retardant coating may comprise a chlorinated vinyl copolymer system which includes a quantity of ammonium polyphosphate, zinc borate, or magnesium and calcium carbonates.
  • the foam or sponge may comprise polyurethane or a silicone coated with silane primer.
  • Party walls are constructed to divide the entire roof space into separate sections so that each house of the terrace has its own roof space for storage or other purposes.
  • Party walls are generally constructed by securing sheets of plasterboard to roof trusses.
  • the continuous nature of the roofing felt and the wooden battens used to retain the felt in place represent potential fire hazards.
  • the continuous lengths of roofing felt and the battens can encourage the spread of fire from one roof space to an adjoining roof space, and so on.
  • a fire in one property of a terrace can - and often does - lead to severe fire damage to all properties of that terrace.
  • the roofing felt was cut tight up against the party wall and against the neighbouring roof truss remote from the party wall to create a continuous break in the roofing felt.
  • a fire curtain impregnated with a material which intumesces in the presence of fire was then adhered to the truss using an intumescent-containing adhesive and then firmly secured to the truss using fireproofed battens and large headed clout nails.
  • the fire curtain was then pulled along the underside of the exposed roof tiles and secured to the party wall using the tumescent-containing adhesive and fire-proofed battens. In this way an effective fire barrier was created between the adjoining roof space sections.

Abstract

L'invention concerne une barrière coupe-feu pour des combles qui comprend un rideau pare-flammes imprégné ou revêtu d'une certaine quantité d'un matériau intumescent. Un adhésif contenant un matériau intumescent est prévu pour faire adhérer le rideau pare-flammes à une ou plusieurs fermes ou murs mitoyens des combles. Une pluralité de liteaux revêtus ou produits à partir d'un matériau intumescent sont prévus pour fixer le rideau pare-flammes aux fermes ou aux murs mitoyens des combles; et des pièces de mousse souple ou d'éponge, de laine de roche, de feutre céramique ou de laine de verre compressée imprégnés d'un matériau intumescent ignifugeant sont prévues pour permettre de remplir tout espace vide situé entre le rideau pare-flammes et la structure de toit adjacente afin de rendre étanche les combles adjacents, les uns par rapport aux autres.
