Provided is technology to reduce interlayer noise occurring in a multi-story house such as an apartment, and more particularly, an environmental and contextual custom-built artificial intelligence (AI) based, interlayer noise abatement apparatus that defines a standard of interlayer noise based on a user environment or a user-specified context, allows an interlayer noise maker to recognize when the noise exceeding the above standard occurs and allows the interlayer noise maker to voluntarily reduce the interlayer noise, and a method of the same.

The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a TPU cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer with at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A composite comprising a core, a first cover layer and a second cover layer, wherein the core is provided from an uncut flat body, wherein the core is a three dimensional structure having a first main surface and a second main surface, the first cover layer is in contact with the first main surface creating multiple contact areas and the second cover layer is in contact with the second main surface creating multiple contact areas, wherein the multiple contact areas between the first cover layer and the first main surface are offset in x-direction and y-direction to the multiple contact areas between the second cover layer and the second main surface, characterized in that the first cover layer and the second cover layer are different.

Described herein are methods and systems for installing flooring systems that provide waterproofing or water-control capabilities. The flooring systems can utilize a gypsum material or any other self-leveling or concrete material along with a structural board or any other type of cement, wood, gypsum board, compressed board, cellulose fiberboard, sheathing board, or sheet metal material. The flooring systems include a waterproof coating applied to the structural boards to provide the water-control features. The waterproof coating covers seams between structural boards and between structural boards and the subfloor.

A flooring assembly (10) comprising at least one vertically lapped fibrous material layer (14), at least one pressure sensitive adhesive layer (12a) including a flexible substrate (12b), a mesh (12c) and an adhesive (12d) located along the flexible substrate, and at least one moisture impermeable membrane layer (16).

Described herein are methods for installing field-assembled flooring systems that include isolation boards on a wall frame, a subfloor, or on both the wall frame and the subfloor. The underlayment can be a hybrid design that includes a combination of isolation panels and cementitious product. The field-assembled flooring systems can use mold-resistant isolation boards to reduce or eliminate the chances of the onset of mold and effects from water damage. The isolation boards can be installed on floors alone, on walls alone, or on both floors and walls to reduce the onset of mold and/or to reduce damage from water.

Provided is a building material that is disposed between an inter-floor separation layer configured to separate floors of a building having a plurality of floors from each other and a bottom layer disposed above the inter-floor separation layer. The building material includes a support member disposed between the inter-floor separation layer and the bottom layer, having a top surface of which at least a portion contacts the bottom layer, and including a protruding portion protruding downward, extending in at least one direction, and having an inner space and a plurality of damping members disposed between the inter-floor separation layer and the support member and each of which has a lower plate contacting a portion of the inter-floor separation layer and an upper plate contacting a portion of the support member to allow the inter-floor separation layer to be spaced apart from the support member.

A soundproof underlayment membrane is disclosed. The membrane comprises a main layer having a given thickness made of a flexible material and a plurality of points extending from one of the surfaces of the main layer. The points are located on the surface in order to create an absorbing chamber between the main layer and an adjacent surface on which the membrane is placed, while reducing a surface of contact between floor coverings installed on the membrane and the adjacent surface. By combining at least two different structural elements, the membrane is particularly efficient for sound reduction in a construction such as the impact or structure borne noise (Impact Insulation Class—IIC) and the sound transmission or airborne sound (Sound Transmission Class—SCC). Compared to existing membranes in the fields, the present invention provides a light material, easy to manufacture, ship and install, while providing effective soundproof properties.

A flooring system including a finished flooring layer and an overlayment to which the finished flooring layer is coupled. The overlayment has a closed cell foam layer, an adhesive layer applied to a side of the closed cell foam layer, and a peelable layer removably positioned on the adhesive layer. The adhesive layer having a positive coefficient sheer adhesion to the finished flooring layer over a period exceeding three weeks from application of the finished flooring layer to the adhesive layer.

A construction sound dampening pad is provided to avoid pseudo-adhesive state. The construction sound dampening pad mainly has the following features: a foamed layer, made of rubber or polymer materials through a foaming process, and formed with first and second surfaces; first and second porous fiber layers, both being a porous layer structure containing fiber materials, and respectively bonded on the first surface of the foamed layer and the second surface; they are bonded together by attaching the first porous fiber layer to the first surface and attaching the second porous fiber layer to the second surface when the foamed layer is still not cooled and solidified during the process of melting and foaming, so as to form a structure wherein part of the structure of the first and the second porous fiber layers penetrates into the first and second surface to achieve a strong and reliable bonding.
