摘要： Flooring material has an anti-slip, noise reducing pad directly self-adhered to a bottom surface. The pad is formed by applying a foamable PVC material is directly on the bottom surface of the flooring and heating the PVC material to foam the PVC material. The PVC material may then be cooled to form the pad with a definite formed shape having a resilient outer surface layer and a spongy foamy inner structure.

摘要： A floor panel includes a substrate, a decorative layer and a wear layer. The decorative layer is positioned between the substrate and the wear layer. At least one of the substrates, the decorative layer and the wear layer has a thermoplastic synthetic material. The floor panel further includes a foamed backing layer attached to a side of the panel opposite to the wear layer. The foamed backing layer has a density of at least 120 kg/m3 and a compressive strength value as determined in accordance with ASTM D 3575-91 (25%) of at least 210 kPa.

摘要： A method of reducing sound transmission in a building constructed using horizontal cross laminated timber (CLT) panels to provide a floor of the building and a floor assembly are described. In an implementation, the method includes: attaching a plurality of energy transmission control mounts to a ceiling side of one or more of the cross-laminated timber panels using fasteners; attaching a plurality of furring channels to the energy transmission control mounts; and attaching a cross laminated timber sheet to the plurality of furring channels to form an exposed ceiling layer.

摘要： Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The structural boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like.

摘要： In an aspect a method of manufacturing an acoustic floor panel is described. The method may include: combining a binding agent with plastic flakes; passing the plastic flakes and the binding agent to a lamination machine; applying a force to the binding agent and the plastic flakes using the lamination machine to create a plastic sheet; cutting the plastic sheet; and adding an acoustic insulator to at least a first side of the plastic sheet.
