Sheet material includes at least two layers of material, wherein a first layer of material forms more than half the thickness of the sheet material and is mainly built up from wood particles glued by means of a first binder and pressed. The first binder is thermosetting, wherein the second layer of material is present on the surface of the aforementioned sheet material and is mainly built up from particulate particles glued by a second binder and pressed. The second binder is thermoplastic and/or elastomeric.

A floor panel includes at least two reinforcing layers extending in a direction parallel to a plane defined by the panel to allow one of the at least two reinforcing layers to be situated at a level between 30˜70 percent of a thickness from a top surface of the panel to a highest part of a top surface of the tongue, and/or a bottom surface of the panel to a lowest part of an upper surface of the lower lip.

Building materials such as structural panels, beams, roof decking, and flooring panels, are packaged within a protective layer including a sublayer of a polymeric material that can be applied at the factory. The protective layer protects the underlying building materials from exposure to weather and potential damage due to handling during shipping, at a job site, and which can be left in place during construction, thus eliminating the need for temporary protective measures covering the building materials. The protective layer may have additional properties such as breathability, fire resistance, and sound absorption. The protective layer also may provide an underlayment such as for flooring and roofing.

A composite board includes a fireproof layer and a first plank layer arranged on the fireproof layer. The fireproof layer has a first thickness. The first plank layer has a second thickness. The first plank layer is stuck to the fireproof layer by waterproof glue.

A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

In the field of decorative floor coverings, decorative panels are known having a MDF (Medium Density Board) or HDF (High Density Board) based core layer on top of which a decorative substrate is attached to provide the panels a desired appearance. The invention relates to a panel, in particular a decorative panel, a floor panel, a ceiling panel or a wall panel. The invention also relates to a floor covering consisting of a plurality of mutually coupled panels.

The present invention provides a decorative sheet having excellent work characteristics, weather resistance, and scratch resistance and a decorative material using the same. Disclosed are a decorative sheet including a base material and a surface-protecting layer, wherein at least one of the base material and the surface-protecting layer contains a white pigment, the surface-protecting layer is a cured product of a curable resin composition, and a Martens hardness of the decorative sheet is 9 N/mm.sup.2 or more and 25 N/mm.sup.2 or less; and a decorative material using the same.

The invention herein provides biofabricated leather materials, solutions comprising collagen that can be used to create biofabricated leather materials, articles comprising biofabricated leather materials, methods for making biofabricated materials, methods for applying biofabricated proteins to substrates and methods for making three dimensional biofabricated materials.
