A viewing panel for location within a door or like structure comprises a frame within which are retained fixed and slidable apertured plates located between fixed sheets of transparent material. The slidable plate is movable by an arm secured to the plate which protrudes through an elongate slot formed in one of the transparent sheets between a first position in which the or each of its apertures is aligned with that or each of the apertures of the fixed metal plate and a second position in which the or each aperture is aligned with one or more land sections of the fixed plate. The land sections of one or both metal plates carry strips of intumescent material which intumesce in the presence of excessive heat completely to fill the panel interior.

A cover for a conduit fitting comprises sheets of preformed flexible cellular fire-retardant foam or sponge joined together by an intumescent adhesive to form a cover open on one of its sides and dimensioned to define a reasonably snug fit about the external walls of an open-sided conduit fitting. Each sheet is coated firstly with a primer solution including a sealant and secondly with a flowable coating of a fire-retardant material. The primer solution operates to close the open pores of the surface and provides a bond to which the fire-retardant coating can adhere.

A fire-resistant barrier for roof spaces comprises a fire curtain impregnated or coated with a quantity of an intumescent material. An intumescent-containing adhesive is provided to adhere 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 are provided to secure 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 are provided to fill all gaps present between the fire curtain and the surrounding roof structure to seal the adjoining roof spaces one from the other.
摘要:
A threshold comprises a threshold strip (1) extruded from a plastics material whose profile includes along each of its lengthwise extending sides (3) inwardly facing channels (7) between which are retained lengthwise extending side edges of a strip of carpet material (9) mounted onto a plastics backing strip and secured thereto by hot melting. The plastics material is preferably a high tensile plastics material.

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.
摘要:
An intumescent fire seal for location about a structure such as a door or door frame comprises an elongate flexible strip (4) of plastics material to one surface of which is secured a brush or blade seal (2) which upstands from that surface. A layer of intumescent material (1) is bonded to at least part of the strip surface.
摘要:
A fire-resistant spacer for separating tiled or slatted roof structures of adjoining buildings or building sections comprises at least one sheet of intumescent material (1) and at least one sheet of deformable material (2) sealed within an envelope of flexible material (3), and a rib (4) of flexible cellular fire-retardant foam or sponge in contact with an exposed surface of the envelope (3) between opposed side edges thereof. The arrangement is such that in use the sides of the sealed envelope (3) in which the intumescent material is present extend to positions at which they can be secured to neighbouring roof structure (preferably joists) of adjoining buildings or building sections with the rib (4) extending between these neighbouring structures and to a height at least equal to the height of neighbouring tile battens (6) of the roof structures, the sealed envelope (3) and rib (4) being subsequently covered by roof tiles (8).
