A drywall system is provided including a first drywall panel and a second drywall panel connected to the first drywall panel via a main hinge. A first drywall flap connected to the first drywall panel via a first hinge, and a second drywall flap connected to the second drywall panel via a second hinge. The first drywall panel, the second drywall panel, the first drywall flap and the second drywall flap can hinge to assume at least one corner configuration in which the first and second flaps lie on a first plane, the first drywall panel lies on a second plane and the second drywall panel lies on a third plane, such that the first plane, the second plane and the third plane are mutually orthogonal. A coating can be provided on an external surface of the framing drywall liner for strengthening the groove which, in embodiments can be polyester strip that extends over portions of the first and second gypsum-containing segments on either side of the of the groove.

Structures including a curved corrugated wall fabricated from a plurality of layers formed of one or more shaped strips and methods of forming the structures are described. A shaped strip used in the fabrication includes a variable profile across the width of the strip with a first edge of a strip defining a series of cell profiles of a first geometric shape and a second, opposite edge of the strip defining a series of cell profiles of a second, different geometric shape, with each cell transitioning from the first profile to the second profile across the width of the strip. The geometry of the cell profiles at either end of each cell can be designed with respect to one another to allow for radial orientation of the strip about an axis with little or no deformation or stress on the strip edges.

The present invention relates to a wood board (1) for outdoor decking (8) use, which board has been sawn from lumber close to bark side of the lumber, with a thickness in the range from about 10 mm up to about 32 mm, the wood board (1) comprises a first side (2) and an opposing second side (4), the first side (2) can be arranged as an upper side of the wood board (1) and the second side (4) can be arranged as a lower side of the wood board (1), or vice versa, between the first side (2) and the second side (4) the board (1) has two opposite short sides (9, 11). The wood board (1) is provided with a convex first side (2) and a convex second side (4).

A method of fabricating a structure including hanging a flexible fabric in a substantially vertical direction, shielding a portion of the flexible fabric and applying a fixative to an unshielded portion of the flexible fabric, thereby forming a fixed portion of the flexible fabric. A shielded portion of the flexible fabric is located in a portion of the fabric and is configured to act as a hinge allowing the fixed portion to be rotated.
