Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

Provided are wallboard panels comprising laminated multi-ply paper cover sheets bonded with a non-ionic polymeric binder and a cross-linker, and methods for making the wallboard panels.

The inventive disclosures are directed to a factory-controlled process for making improved, risk-optimized commercial-building waterproofing systems. The improved waterproofing-panel systems also include improved intrinsic leak-detection capabilities.

A method for manufacturing a folded panel including the following steps: providing a longitudinal recess at the rear side, such that at the front side between remaining panel sections on both sides of the recess a flexible transition section remains, bending the panel sections relative to each other and applying an adhesive in the recess. Before the panel sections are bent relative to each other, a template is inserted into the recess.

A method for coating of a floor panel and a floor panel produced by the method. A method for producing a laminated product, for example a building panel, preferably a floor panel. The method includes applying a paper on one side of a wood fiber based core, e.g., an HDF panel, creating a décor on the paper by a digital printing process, applying a resin, preferably a melamine formaldehyde resin, on the paper, heating the décor and the paper with the resin, preferably by using an IR lamp; and applying heat and pressure in order to cure the resin and thereby obtain a laminated product. Also, alternative methods for producing a laminated product, and such a laminated product.

A structural panel includes a first skin, a second skin and a core. The core is connected to the first skin and the second skin. The core includes a corrugated sheet of wire mesh that includes a plurality of corrugations. Each of the corrugations extends vertically between and engages the first skin and the second skin.

The invention relates to a decorative panel, in particular a floor panel, ceiling panel or wall panel, and to a method for manufacturing such decorative panel. The panel according to the present invention comprises includes at least one foamed layer comprising including an upper side and a lower side, and at least one decorative solid layer either directly or indirectly, affixed on said upper side of the foamed layer, wherein both the foamed layer and the decorative solid layer are wood based materials. The invention also relates to a floor covering consisting of a plurality of such panels.

Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.

Described herein is a building panel comprising a body comprising a first fibrous material comprising inorganic fiber, a non-woven scrim coupled to the body; and wherein the non-woven scrim has a thickness ranging from about 8 mils to about 20 mils.

The present invention relates to a floor panel 10, in particular for the outdoor area or wet areas, with a carrier plate 11 having a front face and rear face, wherein the carrier plate 11 is provided on its front face with a décor and/or protective layer 16. For drainage of liquids and in particular of water, on the rear face of the carrier plate 11 drainage protrusions 22, 24, 26, 32 are applied.
