Each of the functional roof modules includes a module housing and a roof functional unit which includes three different roof functional panel units selectively supported by the module housing at different levels thereof to provide different functions for the building. The roof functional panel units are selectively configured for selectively providing multiple functions of solar energy collection, thermal insulation, sound insulation, wireless network system, and the like.

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.

The present disclosure relates to a precast load bearing roof deck element for a building comprising an upper floor layer of concrete, a load bearing steel reinforced lower layer of concrete, at least one thermally insulating layer located between and separating the upper floor layer of concrete and the lower layer of concrete, and a plurality of binders extending between the lower layer of concrete and the upper floor layer of concrete, the roof deck element configured to be mounted on a load bearing construction of the building. The disclosure also relates to a roof construction comprising a load bearing construction, such as a column and beam construction, and at least two of the above mentioned precast load bearing roof deck elements, wherein the roof deck elements are positioned side by side forming a gap between the roof deck elements, wherein the distance between the roof elements is between 0 mm and 100 mm, or between 1 mm and 100 mm. Furthermore the present disclosure relates to a method for manufacturing a load bearing roof deck element and a method for installing a roof construction on a load bearing construction of a building.

A roofing board, such as a polyiso insulation board, includes first and second surfaces, where the first surface is lighter in color than the second surface. This allows the roofing installer to choose which of the surfaces to expose to the atmosphere, the lighter surface being cooler than the darker surface. The lighter surface may have a solar reflectance greater than the darker surface. A roofing membrane is then adhered or otherwise attached to the exposed surface.

Structural insulated wall and roof sheathing systems for use in building construction designed to provide a structural building envelope that is moisture permeable but protects from bulk water, excess air, and thermal transfer.

This invention relates to prefabricated, lightweight, multi-component structural modular building panels and modular building systems. The said panels are framed with edge members that have a unique connecting shape, making them modular. The multi-component panel allows for design flexibility and the mass manufacturing of its components. Connectors serve as a link to assemble the panels together, and to connect them to corners, floors or foundations, roof panels and the roof apex member, and or other conventional construction elements. Connectors and members, all with unique connecting shapes, coupled with the said panels, create a structural wall, roof, similar structure or building system. Assembled panels and members incorporate the primary building structure and the building envelope. The assembled panels, members and other components of the building system, in part or whole, can be flat packed for easy transport and shipping, and can be assembled quickly and easily with semi-skilled labor.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

A roofing system with interlocking structural panels that have an outer, exterior side surface adapted to be exposed to weather, and an inner side that faces the interior of a structure when installed. The roofing system generally can include a first plurality of structural panels and a second plurality of structural panels, with at least one of the pluralities of structural panels including roofing panels, and the other plurality of structural panels including photovoltaic modules or solar panels that can be mounted in series with the roofing panels to form the roof structure. The structural panels of the roofing system are configured to act as structural components for construction of a roof structure, and are further adapted and/or constructed to be easily handled and installed by individual installers.

The present application relates to the technical field of architectural engineering. Disclosed are a slab joint leakage-proof structure of a prefabricated roof panel, a prefabricated roof panel and a prefabricated roof panel system. The slab joint leakage-proof structure comprises a first leakage-proof layer. The first leakage-proof layer comprises two flexible structures which abut against each other and are arranged at the joint of a main rib on the long side of the roof panel and a main rib on the long side of an adjacent roof panel. Either of the flexible structures comprises a main body portion sealably attached to the main rib, and at least one protruding portion which is fixedly disposed on the main body portion, protrudes and extends into the joint, and can tightly abut against the other flexible structure. The protruding portions of the two flexible structures can enclose an air cavity layer sealably isolated from the outside. The air pressure of the air cavity layer is higher than that of the outside for preventing liquid on the bottom end of the joint from permeating into the air cavity layer and entering a room. The slab joint leakage-proof structure has good waterproof performance. The flexible structures are sealably connected to the main ribs, and are not easy to fall off, and the problem that the waterproof performance is poor due to the fact that a mortar is easy to fall off in an existing waterproof mode of filling the mortar is solved.
