An integrated roofing product comprising a wood or cellulosic structural or roof sheathing base or core panel with a rigid foam insulation sheet or layer laminated or otherwise attached to the panel's inner face. Shingles and/or other protective material may then be attached to the panel's outer face. A plurality of parallel air channels extend vertically in the rigid foam insulation sheet or layer, providing a pathway for air to pass up and out of the eave space. Some or all of the air channels are disposed on the surface of the foam layer that is laminated or attached to the panel's inner face, so that part of the air channel is formed at the interface. A radiant barrier layer may be placed on the inner face of the rigid foam insulation sheet or layer, or between the foam insulation and the inner face of the roof sheathing base or core panel.

Insulated wall and roof sheathing systems for use in building construction designed to provide moisture permeable wall panels that protect from bulk water, excess air, and thermal transfer.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

A composite structure joining system and method comprises a structural panel, preferably but not necessarily fabricated from structural composite materials, that further comprises a nesting C-joint feature that facilitates assembly of a plurality of panels of the invention to form a planar structure such as a wall. An embodiment of the present invention comprises a plurality of the panels of the invention, joined together using the C joint of the invention, captured in a frame. The frame structural elements may comprise metals such as aluminum or steel, or may be hand laid or extruded fiberglass as described in more detail below. The invention further comprises methods of manufacturing a plurality of structural panels of the invention. The method of the invention may be used to fabricate intermodal shipping containers that have superior structural and thermal characteristics, are lightweight, resulting in lower transportation costs and lower container costs.

Building panels, especially laminated floor panels are shown, which are provided with a locking system and several core grooves at the rear side in order to save material and decrease weight. Building panels, each having a surface layer on a front side, a backing layer on a rear side and an intermediate core, wherein the intermediate core and the surface and the backing layer all comprise wood fibres and thermosetting resins, the building panels are provided with a locking system for vertical and horizontal locking of a first edge of a first building panel to an adjacent second edge of a second building panel.

A joint member (1) for mechanically connecting a first panel (51) and a second panel (52) to each other has a body (20) equipped with at least four connecting portions (21, 22, 23, 24) each having a respective seat (31, 32, 33, 34) which receives a fixing element (5). The seats (31, 32, 33, 34) are spaced from each other and, in a plan view of the joint member (1), are positioned at the vertices of a quadrilateral. A first (21) and a second (22) of said connecting portions form a first pair of connecting portions, to be fixed to the first panel (51), whereas a third (23) and a fourth (24) of said connecting portions form a second pair of connecting portions, to be fixed to the second panel (52). Each connecting portion (21, 22, 23, 24) has a first face (41), which is facing the respective panel (51, 52) in use, and a second face (42), which is on an opposite side to the first face (41). Each seat (31, 32, 33, 34) is, or comprises, a through hole which extends between the first face (41) and the second face (42). The second face (42) of the first connecting portion (21) and the second face (42) of the third connecting portion (23) are on a same first side (25) of the body (20); the second face (42) of the second connecting portion (22) and the second face (42) of the fourth connecting portion (24) are on a same second side (26) of the body (20), opposite to the first side (25). An assembly (57) comprises a first panel (51), a second panel (52), at least one joint member (1) and a plurality of fixing elements (5). A wall (58) for a building or a floor for a building is formed by a plurality of panels (51, 52, 53) and comprises at least said assembly (57).
