A radon gas and/or moisture abatement system (or method) is located under the concrete slab of a building. The system (or method) includes a multilayered mat having a first layer, a second layer, and a third layer sandwiched between the first layer and the second layer. The first layer is non-permeable and faces the concrete slab. The third (or sandwiched) layer is an entangled net. The second layer is permeable layer. The layers are bonded together. Whereby radon gas and/or moisture are inhibited from entering the building by passing through and collecting in the multilayer product.

A foundation packing 1 includes a pair of long packing main bodies 2 and connectors 3. The paired long packing main bodies 2 include a first packing main body 11 and a second packing main body 12. The connectors 3 bridge the paired packing main bodies 2. The connectors 3 are provided at intervals in the longitudinal direction of the paired packing main bodies 2. The first packing main body 11 includes a long top plate 21, a long bottom plate 22, vertical plates 23, and reinforcing shelf boards 24. The top plate 21, the bottom plate 22, and the vertical plates 23 form ventilation passages 30 penetrating the packing main bodies in the width direction of the foundation packing 1. The reinforcing shelf board 24 divides each ventilation passage 30 into two in the up-down direction.

A cross-laminated panel including a first layer, a second layer, and a third layer. The first layer of the cross-laminated panel having first boards oriented in a first direction. The second layer of the cross-laminated panel having second boards oriented in a second direction, the second direction being substantially perpendicular to the first direction. The third layer of the cross-laminated panel having third boards oriented in the first direction. The cross-laminated panel also including adhesive situated between each of the first layer, the second layer, and the third layer. The cross-laminated panel further including a hollow member forming a conduit and disposed in any one of the first layer, the second layer, and the third layer.

The present application discloses a rainproof curtain wall, an assembly for fabricating the same, and a waterproof moisture-permeable roll material having the same. The rainproof curtain wall includes an inner lining layer, a plurality of resilient bumps arrayed on a side of the inner lining layer, and a surface layer provided on a side of the resilient bumps departing from the inner lining layer. The present application can provide good effects of drainage and ventilation, reduce the costs of materials and man power, save the cost of construction and prolong the service life of a building.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

A ventilation screed comprising: an attachment flange having a top portion and a bottom portion; a drip edge protruding from the attachment flange and a return leg that protrudes back from the drip edge, wherein the drip edge is angled downward in a first direction and the return leg is angled downward in a second direction; a drainage cavity protrusion protruding from the attachment flange above the drip edge, wherein the drainage cavity protrusion has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion and a substantially vertical portion with a top end and a bottom end in communication with the bottom portion, an upper ground portion in communication with the top end of the substantially vertical portion of the L-shaped drainage trough portion extending outward from the substantially vertical portion and a drainage cavity shroud extending substantially downward from the upper ground portion.

A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

A wall (or roof) system includes: an exterior sheathing covers a frame, a plurality of spaced apart battens are affixed on the sheathing, and a siding in contact with the battens. Each batten includes: a backweb having two sides and a length, a plurality of elongated piers upstanding on each side of the backweb, each pier running the length of the backweb, and each pier having a distal surface, and a first air flow channel defined between adjacent piers and a horizontal pier cutting through adjacent piers. Air flows between airspaces created between the exterior sheathing and the siding by the batten. Air also flows through the first air flow channel and this air flow may reduce moisture entrapment between the batten and the siding or the exterior sheathing. The batten may also have a second air flow channel at an angle to the first air flow channel.
