A folding mat includes a first cover part into which a plurality of first cushioning materials are inserted; a second cover part into which a plurality of second cushioning materials are inserted and which is foldably connected to the first cover part; a first opening and closing part formed from a first point of a first side of the first cover part to a second point of a second side of the first cover part, and opening at least two sides of the first cover part to allow the plurality of first cushioning materials to be inserted; and a second opening and closing part formed from a third point of a third side of the second cover part to a fourth point of a fourth side of the second cover part, and opening two sides of the second cover part allowing the plurality of second cushioning materials to be inserted.

The present disclosure describes a contiguous sound attenuating panel system. The sound attenuating panel has a top surface, a bottom surface, a first end, a second end, an adhesive strip on the top surface of the first end, and an engagement flap on the top surface of the second end. The adhesive strip has a first edge and a second edge. The second edge is located further from the first end than the first edge. When installed, the first end of a first sound attenuating panel abuts and is substantially coplanar with the second end of a second sound attenuating panel. The width of the engagement flap of the second sound attenuating panel terminates substantially at the location of the second edge of the adhesive strip of the first sound attenuating panel such that the engagement flap contacts and substantially covers the adhesive strip.

In a sound absorption panel formed by stacking a plate perforated with a hole having a hole size smaller than a fiber length such as expanded metal, a honeycomb material, and felt-like fiber between the perforated plate and the honeycomb material, and joining the perforated plate, the felt-like fiber, and the honeycomb material to each other with an adhesive, the adhesive applied to the perforated plate is permeated into a surface of the felt-like fiber exposed from the hole to fix the fiber on the surface.

The present invention relates to a multifunctional wall covering, a method for manufacture thereof and a method for arranging thereof. The object of the invention is to provide a new wall covering system with which aesthetic properties can be combined in an efficient manner with additional functional properties in general, and more particularly with acoustic properties. The wall covering comprises a strip of material which is longer than it is wide for attachment to wall or partition with at least a first layer and a second layer connected to the first layer which first layer consists of a porous, sound-absorbing textile material, and which second layer consists of an air-permeable textile material and which second layer is provided with a design, which strip of material is at least 2.2 m wide, at least 1.5 mm thick and a maximum of 10 mm thick. The method for manufacturing a multifunctional wall covering is characterized in that the method comprises of providing the strip of material with a design using a known large-format printer or a similar large-format printing system. The method for arranging a strip of the wall covering of the above specified type is characterized in that a wall or partition with a height smaller than or the same as the width of the wall covering is covered seamlessly by the wall covering, whereby an aesthetically high-quality wall covering is realized.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

The present disclosure describes a sound attenuating flooring system. The sound attenuating flooring system has a subfloor, a sound attenuating material overlaying and contacting only a portion of the subfloor, and an overlayment. The sound attenuating material has a first surface and second surface. The first surface is defined by a plurality of outwardly projecting hollow protrusions. The second surface is defined by a plurality of open recesses corresponding to the plurality of outwardly projecting hollow protrusions. The overlayment overlays the second surface of the sound attenuating material.

A method of manufacturing a building element, including applying a first layer on a first surface of a substrate, the first layer including a mixture of a binder, at least one filler and fine non-pigment cohesive particles, wherein an amount of the fine non-pigment cohesive particles in the mixture may be between 0.05 wt % and 9 wt % of the mixture, and applying heat and/or pressure to the first layer and/or the substrate thereby forming the building element. The disclosure further relates to such a building element.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

A multifunction panel for use in a building defines an interspace, optionally for the passage of air, and includes a first layer having a plurality of first shaped through-holes of a first predetermined diameter; a second layer having a plurality of cells defining a honeycomb or ribbed structure; a third layer having a plurality of second shaped through-holes of a second predetermined diameter, the first and the second holes being selectively open at the opposite ends of respective cells, so as to create a first configuration of a cell providing for the transit of air between the interspace and the internal environment, or vice versa, when a first hole opens at a first end and of a cell at a second hole opens at a second end of the cell, and further generating a Helmholtz resonator.

The invention relates to a multi-layer panel for producing a floor covering exhibiting sound-insulating properties, of which at least one of the layers is made from PVC, the said panel comprising male-female means for connecting or assembling several panels together, the said panel comprising at least one decorative layer bonded to a backing layer, the latter being bonded to a nonwoven textile sublayer intended to be in contact with the ground with a thickness of between 0.5 mm and 3 mm.
