A method of reroofing a roof by applying composite recovery boards of the present invention to a roof deck; and, applying a weather protective layer over the recovery boards. A continuous method of making a composite recovery board by feeding gypsum board (14) into a laminator assembly (21); depositing a foamable polymer liquid (36) onto the gypsum board; feeding a facer material (15) into the laminator assembly above the foamable polymer liquid; allowing the polymer liquid to rise between the gypsum board and facer material forming polymer foam of a pre-determined thickness; curing the polymer foam under heat (44) to create the composite board; and cutting the composite board to desired lengths.

Construction systems for erecting building structures comprise a plurality of prefabricated interconnectable modular building units, each unit not meeting at least one of the ISO certification criteria for transport of cargo, but each unit comprising a frame shaped as a rectangular parallelopiped and comprised of framing members and a plurality of nodes, each node situated at a corner of said frame for selective interconnection with other units, the nodes and the exterior dimensions of the frame conforming to ISO shipping standards such that each unit is transportable using the ISO intermodal transportation system, and such that when the units are aggregated horizontally and vertically and adjacent units are interconnected, a building structure comprising at least one habitable space is formed. The modular units are assembled in a factory remote from the job site, and are there constructed to a semi-finished state, including installation of one or more of interior fit-out systems and finishes, exterior envelope systems, plumbing systems, electrical systems, environmental systems, and fire protection systems, following which the semi-finished modular units are transported from the factory to the job site, where they are craned into place and secured to form the structure being erected, a plurality of adjacent pairs of semi-finished modular units also being “stitched” together, and the semi-finished modular units are thereafter constructed to a finished state.

The present invention is a polymeric panel system and method for production and use thereof, enabling the rapid construction of a building foundation wall or other structure and in particular a below-grade foundation. The polymeric foundation system includes polymeric wall panels and other components suitable for withstanding lateral and end compression loads. The walls include two parallel faces separated by a series of webs or ribs, where the webs and faces of the wall panels may be formed of a similar polymer material such as polyvinylchloride (PVC). The wall panels and / or other components may be extruded so as to enable the rapid production of sections of wall panels, where the panels may be cut to length and then affixed to adjacent panels to form a foundation wall. The method of affixing adjacent panels may include welding, gluing or other techniques and may be performed on the job site or in a pre-fabrication facility. Furthermore, the wall panels may be co-extruded with an insulating material inserted in the voids between the parallel faces so as to provide improved thermal performance of the foundation as well.

Floorboards for installation of floors in herringbone pattern are formed with two opposite sides inverted relative to each other. The invention further comprises methods for producing and making floorings comprising such floorboards, as well as fitting pieces and sets of parts for such floorings.

A composite panel consisting of outer skins and an inner core consisting of a foamed polymer, wherein the structure or properties of the inner core are anisotropic. The composite panel can be made by applying external heat and pressure to melt a skin of thermoplastic composite and an initial thickness of a thermoplastic core which has anisotropic properties causing the skin and core to fuse together followed by cooling the fused structure. The composite panel can be made by applying external heat and pressure to melt layers of a thermoplastic adhesive positioned between the outer skins and an inner core consisting of a foamed polymer, wherein the structure or properties of the inner core are anisotropic, so that the skins are bonded to the core by the melted layers of the thermoplastic adhesive followed by cooling the bonded structure.

A joint (1) having a first edge (2) and a second edge (3), the first edge (2) being provided with a distal edge (21) and a downwards protruding heel (22). The distal edge (21) is further provided with an upper joint edge (25) beneath which a groove (23) is arranged. The second edge (3) is provided with lower cheek (31) having a distal end (32) at which an upwards protruding lower cheek heel (33) is arranged. The second edge (3) is further provided with an upper joining edge (35) beneath which an undercut (34) is arranged. A moveable locking element (40) is arranged in the space created by the undercut (34). The moveable locking element (40) have a locking tongue (41), a locking tongue leg (42) and a maneuvering leg (43).

A set of moisture proof floorboards and a flooring of such floorboards with a resilient surface layer provided with a decorative groove and / or a sealing means.

Building panels 1, 1′ provided with a mechanical locking system including a tongue 30, at first edge 4a of a first building panel 1, cooperating with a tongue groove 20, at a second edge 4a of an adjacent second building panel 1′, for vertical locking of the building panels and a method for producing such building panels 1, 1′. The method includes the step of forming the tongue of material of the first edge. The insertion groove (40) may have a sidewall (60) at a third edge (5a), which is adjacent the first edge (4a), and may be open at a fourth edge (5b), which is opposite the third edge.

A gypsum board which comprises a set gypsum core sandwiched between and faced with fibrous mats, wherein a free surface of one of said mats is pre-coated with a combination of a mineral pigment, optionally an inorganic adhesive binder and an organic binder, preferably a hydrophobic, UV resistant polymer latex adhesive binder applied to said surface as an aqueous coating composition, said aqueous coating composition upon drying and setting providing a pre-coated mat satisfying certain morphology requirements.

A method of continuously forming a multilayer panel includes making a gypsum slurry, then dividing the gypsum slurry into at least a primary gypsum slurry and a secondary gypsum slurry. An additive slurry having water and an intumescent material is created, then added to the secondary gypsum slurry to make an expandable layer slurry that is spread over at least a portion of a facing material. The primary gypsum slurry is distributed over the secondary gypsum slurry over the facing material and the expanding layer slurry to form a core. Optionally, another layer, an edge coating, is applied to the expanding layer for additional fire protection. The edge coating includes a second intumescent material. During a fire, the expanding layer expands to increase the thickness of the fire exposed gypsum panel and the edge coating expands to seal the gap between adjoining gypsum panels.
