A multi-component fire-resistant (FR) assembly for use in various forms of construction. The FR assembly attains 30 minutes, 1-hour, 2-hour, or 3-hour fire resistance from either side (in accordance with ASTM E119 criteria), and does not require any added FR panels or sheathing. The FR assembly comprises an interior layer, a plurality of supporting studs, an exterior layer, a weather-resistant barrier (WRB) layer, and, in some embodiments, an outer layer. The placement of the studs creates a cavity or cavities between the interior layer and the exterior layer, which may be filled with an insulating or similar material.

A universal barrier system includes universal barrier components that may be assembled together to shield floors and walls from moisture and provide a thermal break in an operational area of the universal barrier component. A lap zone of the universal barrier component may allow universal barrier components to be assembled and installed to protect floors, walls, ceilings, footings and the like from moisture and heat gain or loss by minimizing the need for tapes and other joining methods. The universal barrier system may also act as a sound deadening material. The operational area and lap zone of the universal barrier component may be disposed on a vapor block layer to provide some rigidity. The operational area of the universal barrier component may include a thermal break disposed upon the vapor block layer. The thermal break may include an outer protective layer. In addition, universal barrier tape and universal barrier edging may be provided to couple adjoining universal barrier components.

A prefabricated building module is described. The building module may provide structural stability for a building, including when stacked with like building modules. The building module may provide a service riser for the building. The building module may provide fixtures for the building, including bathroom, kitchen and laundry fixtures. Also described is a building including prefabricated building modules and a method of constructing a building using prefabricated building modules.

Foam wall structures and methods for making them are described. The wall structures include a frame, a sheet metal sheathing overlying a front surface of the frame, a foam panel overlying the sheet metal sheathing, and a foam layer disposed in a cavity defined by the frame and the sheet metal sheathing. Buildings that include such wall structures are also described.

Bamboo lumber products and fabrication techniques thereof are provided. Thick-wall bamboo culm is cut into multiple slats, each made up of a solid portion of culm. The slats are laminated, joined, or otherwise combined to form solid panels, boards, or other lumber products. The use of thick-walled bamboo and associated processes as disclosed allows for lumber products that have a lower glue-to-bamboo ratio and therefore provide superior characteristics compared to conventional techniques and products.

An artificial insulated log that has outer and inner wood members that are glued to an inner core of rigid insulation. In addition to the glue, structural connectors are fitted on the top of the logs at specified intervals to provide additional structure support, Each of the wood pieces has a tongue and groove formed to receive other logs. In addition, the insulated core is also fitted with a tongue and groove for alignment. The outer, or exterior, wood member is curved to look like a natural log, The inner wood members are cut flat to for a flat interior wall. Formed corner logs can be used with regular logs to make a finished looking assembly for the building. The corners can be alternated or stacked, as desired.
