20110297291 | System and Method for Constructing Composite Building Boards Using Thermoplastic Films - Disclosed are building board manufacturing techniques that minimize the build-up of slurry on associated forming equipment and also produce panels with enhanced physical properties. The methods involve applying a dissolvable film laminate to one or more fiber mats at the outset of the forming process. In the un-dissolved state, the film acts as a containment envelope for the gypsum slurry and any free floating glass fibers. During subsequent curing, the film is dissolved by vaporized water. In its dissolved state, the film is liquefied and coats the fibers of the underlying mat. This results in a building board with improved physical properties. | 12-08-2011 |

20120308795 | Composite Floor Underlayment With Thermoplastic Coatings - Disclosed is a flooring system consisting of a slab (or base) floor, a floor covering, and a composite underlayment extending between the slab floor and floor covering. The composite underlayment may include, for example, one or more set gypsum layers with embedded fibrous mats. An exterior plastic coating is mechanically adhered to an underlying set gypsum layer. The plastic coating chemically bonds and cross-links with polymer additives within the set gypsum core. The result is an underlayment that is a fully integrated polymer matrix with greatly improved durability and surface strength with only minimal increases in cost or weight. | 12-06-2012 |
20130295286 | Plastic Coated Composite Building Boards and Method of Making Same - Disclosed are composite building boards and associated manufacturing methods. The composite boards may include, for example, one or more slurry layers with embedded fibrous mats. An exterior plastic coating is mechanically adhered to the underlying slurry layer. The plastic layer chemically bonds and cross-links with polymer additives within the slurry layer. The result is an integrated polymer matrix with greatly improved durability and surface strength. | 11-07-2013 |

20130327461 | System And Method For The Construction Of Bound Fibrous Mats - Disclosed is a system and method for constructing fibrous mats. In accordance with the disclosure, continuous lengths of filament are pre-coated with a liquefied thermoplastic. The pre-coated filaments are then laid down upon a belt to forum a fibrous mat. The filaments can be laid down in continuous lengths or they can be chopped into discontinuous lengths. The filaments are heated after they have been laid down in order to re-liquefy the thermoplastic and facilitate bonding between intersecting fibers. The disclosure further relates to a system and method for incorporating constructed fibrous mats into a composite building board. | 12-12-2013 |
