A flame retardant insulation module that includes an air layer-forming part including a first air layer-forming part and a second air layer-forming part disposed below the first air layer-forming part, which are disposed so that at least a portion of one does not overlap with a portion of the other; a lower end cover part that covers the lower end of the second air layer-forming part to separate the lower end from an external space; and an intermediate separation part for separating a first air layer and a second air layer. As such, heat insulation performance can be maximized, such that the insulation module has flame retardancy even when a fire occurs.

A wall structure having an inner wall, a bracket member, a non-combustible board, and an outer cladding coupled together and retaining insulation between the inner wall and the outer cladding. The non-combustible board is positioned between the bracket member and the outer cladding.

Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The structural boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like.

A building wall includes an exterior surface and an interior surface. The exterior surface faces the exterior of the building and the interior surface faces an interior room of the building. The wall has a total wall thermal resistance between the exterior surface and the interior surface. The wall includes a structural member positioned between the exterior surface and the interior surface, and the structural member is configured to bear at least a portion of a vertical load of the wall. An insulated composite wall panel is positioned between the structural member and the interior surface. The insulated composite wall panel includes a skin layer including glass fibers and a cellulose fiber insulation board attached with a resin to a first surface of the skin layer. The thermal resistance of the cellulose fiber insulation board comprises the greatest component of the total wall thermal resistance.

A multilayer thermal insulation panel for construction and manufacturing method thereof are described. The multilayer thermal insulation panel comprising: a main layer in thermally insulating material comprising a first surface and an opposite second surface; a first backing layer of the main layer connected to the main layer along the first surface; a second backing layer of the main layer connected to the main layer along the second surface. At least one of the first and second backing layers comprising: a reinforcement layer in fibrous material, a fire-resistant layer comprising expansive graphite, and a cladding layer made on the reinforcement layer and configured to be sandwiched between the fire-resistant layer and the reinforcement layer.

A structural assembly using at least one anchor assembly for attaching a first structure to a second structure is described. The anchor assembly has a body having a first face and a second face. The first face is transverse to the second face and has an elongate slot. The second face has a through hole. The body is fabricated from a material that fails at a temperature in excess of 1,000° F. A fastening member is positioned in the elongate slot for connecting the first face to the first structure and for sliding engagement with the elongate slot in response to relative movement of the first structure and the second structure.

A method for installing building panels, the method including forming a composite building panel from a plurality of panels, transporting the composite building panel to the site of installation and lifting the composite building panel by a lifting facility into position within a building.

Described herein are building panels and surface covering systems useful for spaces requiring acoustic control and design flexibility, and methods to prepare the same. Such building panels and surface covering systems comprise an building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber; wherein the first side of the denim web backing is in contact with the upper surface of the body; and wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m.sup.2. In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

A fire-stopping material for use in sandwich panels is provided, wherein the fire-stopping material comprises a resilient, porous material at least partially impregnated with an intumescent agent. A panel for an internal wall and an internal wall are also provided, comprising the fire-stopping material disposed between two substantially parallel boards, such as plaster boards. A method of providing a service penetration through an internal wall is also provided.

A liquid composition including clay containing at least one selected from the group consisting of a montmorillonite, mica, hectorite, and fluorosilicate; and a dimer or higher phosphate is described. Such liquid compositions are capable of forming a fireproof layer having high fireproof performance on a surface of a base material to which a film for wallpaper or the like is applied. A fireproof layer which can be formed using the liquid composition, a laminated structure including the fireproof layer, and a fireproofing method using the liquid composition are also described.
