20150322670 | Soundproofing Panel - A panel for use in building construction comprises a plasterboard having two opposed faces, a polymer-based lamina being provided on one of these faces. The weight per unit area of the panel lies in the range 13.5 to 17.5 kg/m | 11-12-2015 |
20150308739 | Drying System - A drier for drying boards ( | 10-29-2015 |
20150197938 | Polyester Laminated Building Boards With Improved Surface Characteristics - This disclosure relates to using polyester films on building boards to enable improved surface coatings. The polyester film is preferably applied to a glass mat via an adhesive to form a laminate. This laminate is then bonded to the exterior surface of a gypsum board. The polyester film is advantageous because it allows for exterior surface coatings to be applied. In one embodiment, an exterior acrylic coating is applied to the polyester film. Boards constructed in accordance with this disclosure allow for exterior finishings to be achieved without the need for excessive finishing materials or steps. | 07-16-2015 |
20150184386 | Non-Uniform Coatings for Building Boards - Disclosed is a building board construction with increased surface strength. More specifically, increased nail pull strength is achieved via the application of an external surface coating. The surface coating is ideally applied to a paper faced gypsum building board. In one possible embodiment, the coating is formed from a water soluble polymer. | 07-02-2015 |
20150184385 | Building Boards with Increased Surface Strength - Disclosed is a building board construction with increased surface strength. More specifically, increased nail pull strength is achieved via the application of an external surface coating. The surface coating is ideally applied to a paper faced gypsum building board. In one possible embodiment, the coating is formed from a water soluble polymer. | 07-02-2015 |
20150114264 | Gypsum-Based Building Products and Method for the Manufacture Thereof - A building product comprises calcium sulphate dihydrate particles bound by an organic binder. The calcium sulphate dihydrate particles each have a longest dimension and a lateral dimension, wherein the lateral dimension corresponds to the maximum breadth of the particle about the axis defined by the longest dimension. The calcium sulphate dihydrate particles have a low aspect ratio such that for at least 75% of the calcium sulphate dihydrate particles, the value of the lateral dimension is at least 20% of the value of the longest dimension. | 04-30-2015 |
20140374955 | Pressing Assembly and a Method for Forming a Depression within a Moving, Wet Gypsum Board - A pressing assembly ( | 12-25-2014 |
20140329060 | Construction Panel and Manufacture Thereof - A panel for use in building construction comprises a substrate board having two opposed faces. A lamina is secured to a first one of the faces of the substrate board by means of one or more regions of bonding between the lamina and the board. The one or more regions of bonding cover a total area that is less than 20% of the total interfacial area between the lamina and the board. | 11-06-2014 |
20140026786 | Method and Apparatus for Manufacturing Gypsum Products - A method and system for producing a gypsum product comprising a mixer for mixing gypsum and water and two foam feeds into the system wherein the foam feeds each comprise foam of different bubble size distributions. | 01-30-2014 |
20130241629 | Actuator and Method of Manufacture Thereof - An actuator for controlling the operation of an apparatus comprises a panel ( | 09-19-2013 |
20130239848 | Calcium Sulphate-Based Products and Methods for the Manufacture Thereof - The invention provides a calcium sulphate-based product comprising a phosphate as additive for increased fire resistance. Particularly preferred phosphate additives may be those containing aluminium or ammonium ions. | 09-19-2013 |
