A fire-stopping material in a panel for an interior building wall is provided. The fire-stopping material includes a resilient, porous material at least partially impregnated with an intumescent agent.

Disclosed is an exterior wall (17) for a building (11). The exterior wall (17) comprises an inner wall (20) including a load-bearing structure formed by a transversal roof metal profile (14) and a transversal foundation metal profile (13) between which a number of intermediate metal profiles (15) extend, and wherein an inside surface (59) of the inner wall (20) is provided inner sheathing (63). The exterior wall (17) also comprises an outer wall (21) including a load-bearing structure formed by a transversal roof metal profile (14) and a transversal foundation metal profile (13) between which a number of intermediate metal profiles (15) extend, and wherein an outside surface (64) of the outer wall (21) is provided outer sheathing (62). The inner wall (20) and the outer wall (21) are mutually fixed at the transversal metal roof profiles (13) and the transversal metal foundation profiles(14) so that a cavity (34) is formed between the inner wall (20) and the outer wall (21). A method for constructing an exterior wall (17) of a building (11) is also disclosed.

A decorative sheet which ensures good incombustibility, processability and weatherability along with weatherability, contamination resistance and solvent resistance. An incombustible decorative sheet having incombustibility includes a weather-resistant resin layer and a fluorine resin layer laminated on a substrate layer in this order, wherein the weather-resistant resin layer is made of a mixture of an acrylic resin and an acrylic resin-based rubber having a ratio by mass between the acrylic resin-based rubber and the acrylic resin within a range of 30:70 to 60:40. The ratio between the fluorine resin layer and the weather-resistant resin layer is within a range of 10:90 to 40:60.

A method includes providing an article having an impact side and an asset side and exposing the impact side of the article to a plurality of pressure waves, the pressure waves having a plurality of pressure wave frequencies. The method also includes reflecting at least one composite harmonic of a portion of the pressure wave frequencies and reducing an amplitude of a portion of the pressure waves.

A hybrid framed curtain wall panel is used to prevent inter-floor fire propagation from both the interior and exterior, featuring the combined use of three different infill materials for three different functions. The first infill is a continuous exterior fire-resistant thin pane for providing an aesthetic element and for preventing exterior inter-floor fire propagation. The second infill is a small band of fire-resistant material, such as mineral wool panel infill, located at the slab edge for preventing interior inter-floor fire propagation. The third infill is a structural infill, such as composite foam panel infill, to provide a light-weight material with excellent thermal insulation value.

A sheathing material includes a layer of ceramic paper to help prevent the burning of the sheathing during a fire. The material may include insulation disposed between the ceramic paper and the substrate to further reduce damage to the substrate, and may include a thin layer of wood or paper placed over the ceramic paper to protect the ceramic paper and to allow the sheathing to be used in a manner similar to that of a conventional sheathing material.

A method for on-site assembly of a shelter for an above-ground structure to protect the structure from blast, wind, fire or other physical hazards. A pyramidal shelter with triangular or rectangular base is formed by joining side panels to each other. Each side panel includes a triangular frame covered, except at access hatch, observation port and door openings, with either steel plate or diamond steel mesh to which blast-resistant, fire-resistant or other kinds of coatings or panels are applied. A corner anchor assembly to support each corner of a shelter has a lower plate, an overlying split plate, and a pair of upstanding, anchor rods attached to the split plates for insertion into hollow, lower portions of side beams of adjacent side panels. The corner anchor assemblies facilitate expansion of an assembled shelter by addition of more modular components.

A construction board includes a foam body having first and second planar surfaces, said foam body including a polyisocyanurate foam matrix defining a plurality of closed cells, said closed cells being at least substantially devoid of hydrocarbon blowing agents, and said foam body being characterized by a density, pursuant to ASTM C303, of at least 2.5 lbs/ft.sup.3; and a facer disposed on a planar surface of said foam body, said facer including a glass substrate having an internal planar surface proximate to said foam body and an external planar surface opposite said foam body, a first coating disposed on said external surface, and a second coating disposed on or proximate to said internal surface, where said first coating disposed on said external surface includes an inert filler, and where said second coating disposed on or proximate to said internal surface includes intumescent material.

According to one embodiment, a halogen free roof system is described. The roof system includes a structural deck that is positioned above joists or other support members. Polyisocyanurate foam insulation is positioned atop the structural deck. The polyisocyanurate foam insulation has an isocyanate index greater than 200 and includes a polyisocyanurate core having a halogen free fire retardant. A water proof membrane is positioned atop the polyisocyanurate foam insulation. The polyisocyanurate core is able to form a sufficiently stable char when exposed to flame conditions such that the polyisocyanurate core is able to pass the ASTM E-84 test.

A construction material consisting of a deployment system for a tire retardant substance, suitable for use in a wide variety of applications. This invention is designed to deploy a fire retardant substance in in response to the detection of an uncontrolled fire, thus minimizing or reducing risk of death, serious injury or property damage associated with uncontrolled fires when present in a habitable structure. The invention consists of a construction material which incorporates hinged or folding door(s) or flap(s) which contain a fire retardant substance within the construction material. When an uncontrolled fire is detected, the door(s) or flap(s) open and thus deploy the fire retardant substance onto the area affected by the uncontrolled fire.
