Described herein is a wall assembly for use in walls of energy efficient residential or commercial buildings which can provide improved thermal resistance, moisture resistance and structural capacity. The wall assembly includes a frame assembly; a sheathing layer; a closed cell inner foam layer for coupling the layer to the frame assembly; and an outer fiberboard. Also described herein is a method of manufacturing the wall assembly.

Provided are wallboards in which gypsum core is adhered to a paper cover sheet with an adhesive. Wallboards with laminated paper cover sheets in which an inner water-absorbent cover sheet is adhered to the outer paper cover sheet are provided as well. Methods for making these wallboards are provided as well.

It is provided a cross-laminated wood façade element (1) that has an upper end (12) and a lower end (13), an inner surface (3), an outer surface (2) and a longitudinal axis (28) in the direction from the upper end (12) to the lower end (13), said element (1) comprising an inner layer (4) of timber elements (7) and at least one intermediate layer (5) of timber elements (7) where the grain of the timber elements (7) of the inner layer (4) and grain of the timber elements (7) of the at least one intermediate layer (5) are at least partially oriented in different directions, the façade element (1) further comprising an outer layer (6) comprising timber elements (7) in which the grain direction is oriented approximately parallel to the longitudinal axis (28), characterized in that the outer surface (2) of the façade element (1) has grooves (11) that are approximately parallel to the longitudinal axis (28).

A structural insulated sheathing including a rigid foam insulation board having a first face, a structural member having a second face, wherein the first face of the foam insulation board is laminated to the second face of the structural member over substantially 100% of the interface between the first face and the second face.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.
