A sealing for arrangement between a wall and a wall covering includes a sealing sheet and an adhesive tape. The sealing sheet and the adhesive tape each have a carrier layer of a preferably closed-cell foam plastic. Furthermore, the sealing sheet can bear a nonwoven fabric preferably on the wall-facing side, wherein border strips remain free of the nonwoven fabric for underlapping with an adhesive tape.

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).

A floor covering including a flexible underfloor having at least one foamed polymer layer; one or more sheet vinyl floor elements or LVT floor elements, one or more LVT floor elements, or one or more rigid LVT floor elements, an adhesive layer that bonds the underfloor and the floor element to one another.

The invention relates to a decoupling web (1), in particular intended for use for a surface covering structure (2) which can be covered with covering elements, preferably tile coverings, having a carrier web (3) and a multiplicity of nubs (5) projecting from the carrier web plane (4), the carrier web (3) having as material a, preferably thermoplastic, plastic. According to the invention, it is provided that the carrier web (3) comprises as material a copolymer comprising ethylene and vinyl acetate, in particular a copolymer of ethylene and vinyl acetate, preferably ethylene-vinyl acetate (EVA), and/or consists thereof.

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.

A load distributing and absorbing system that lies below a superstructure material which is exposed to percussive forces. The load distributing and absorbing system is interposed between the superstructure material and a foundation. The system has a barrier layer that lies below the superstructure material and an underlayment infrastructure positioned below the barrier layer. Included in the underlayment infrastructure are hat-shaped absorbing members.

An Methods and apparatuses for reducing the transmission of unwanted sound and vibration energy generated by dynamic and/or impact loads through floors in multi-story buildings. This may be accomplished using an acoustic wave transformation and attenuation sound proofing membrane including an acoustic wave transformation layer, an acoustic absorption layer, and a constrained vibration damping layer. The acoustic wave transformation layer may be capable of transforming acoustic waves in a manner that may easily be attenuated by the acoustic absorption and constrained vibration damping layers. The sound proofing membrane may be used with several different combinations of floor coverings, adhesives, and subfloors. Impact acoustical tests have demonstrated that the sound proofing membrane can achieve higher IIC and MC ratings compared to conventional acoustic underlayments and/or membranes and, thus, prevent unwanted dynamic and/or impact loads from disturbing occupants in rooms beneath the floor assembly.

A fibrous structure having one or more vertically lapped layers having a first surface and a second surface and a facing layer secured to the first surface of the vertically lapped layer. The fibrous structure is adapted to be used in a flooring assembly. The fibrous structure may include a mesh and/or a backing layer on the second surface of a vertically lapped layer. The fibrous structure exhibits improved performance in below room testing and/or in-room testing as compared with traditional materials of the same thickness.

A universal membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The universal membrane includes a base layer, a plurality of studs projecting from the base layer, and a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs. Each sidewall of the plurality of sidewalls forming a perimeter of a pocket. The base layer forms a bottom wall of the pocket.

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).
