Coupling system (3, 30) for coupling building panels (1, 2; 31, 32) or sandwich panel comprising two cover sheets (5, 6; 33, 34, 36, 37) and a core (4, 39) of insulating material sandwiched between the two cover sheets, in particular for building a roof structure. The building panels have matching coupling edges (7, 8; 40, 41), profiled to define one or more water discharge channels (19; 59, 64) running substantially parallel to the coupling edges.

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.

A covering having insulated panels is meant to prevent or slow the spread of fire. Each panel has a top cover; a fire-prevention layer having a fire-retardant material, a fire-resistant material, or a combination of both; and an insulation layer. The fire-prevention layer is located, at least partially, between the top cover and the insulation layer. When there are two or more insulated panels, they interlock at a joint and form a plane.

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.

A roof deck (20) has plurality of insulated panels (22) secured together by a first plurality of fasteners (54) along their longitudinal edges (28, 29). Additionally, the panels (22) are secured by a second plurality of fasteners (56), transverse to the longitudinal axis (26), to a framework (18). A plurality of washers (60) disperse the force of the second plurality of fasteners (56). The plurality of washers (60) are secured to each of the second plurality of fasteners (56). A membrane (24) covers the roof deck (20).

Interlocking laminated structural roofing panels have a lightweight foamed core sandwiched between outer and inner layers of materials such as wood, polymer materials, fire resistant and/or waterproof membranes, and metal layers. At least one layer is a self-gripping metal sheet that grips and bonds mechanically to adjacent layers such as wood layers. A self-gripping metal sheet may be used on both sides of the roofing panels to form a panel that is strong, structurally robust, and able to span between relatively widely spaced roof rafters with little or no mid-span support. Interlocking features along the edges of the panels interlock adjacent panels together to form a strong monolithic roof covering for a roof.

A building system including a building panel with insulation, an integrated weather resistant barrier, and sheathing. The insulated building panel increases the energy efficiency of the building system while providing protection against water, air and heat. The insulated building panel is pre-fabricated with the weather resistant barrier for easy installation.
