A fixing system for a panel, particularly for a noise absorption panel, including an omega stringer having a substantially omega-shaped cross-section, wherein the omega stringer includes a central portion and two lateral foot portions; a flat bar longitudinally directly connected to the central portion of the omega stringer; a sealing gasket arranged longitudinally onto the lateral foot portions of the omega stringer or onto the flat bar; wherein height of omega stringer is selected so that, when a panel is clamped between the omega stringer and the flat bar, the sealing gasket is compressed between panel and fixing system.

Described herein is an acoustic building panel comprising: a body comprising a fibrous material and having a first major surface opposite a second major surface and a side surface extending there-between, the fibrous material comprising polyester fiber in an amount of at least 70 wt. % based on the total weight of the fibrous material; wherein the body has a bulk density as measured between the first major surface, the second major surface, and the side surface, the bulk density ranging from about 4.8 lb./ft.sup.3 to about 6.0 lb./ft.sup.3.

The described embodiments relate generally to a micro-perforated panel systems, methods for noise abatement, methods of meeting safe breaking requirements and methods of making micro-perforated panel systems. In particular, embodiments relate to glass micro-perforated panel systems for noise abatement and meeting safe breaking requirements.

In accordance with various embodiments, lighting systems features one or more inter-connectable light panels each having multiple light-emitting elements thereon. One or more of the light panels may feature one or more connectors, and associated conductors, for the transmission of power, communication signals, and/or control signals. One or more of the light panels may include sound-absorbing material therebelow and may define one or more apertures and/or cut-out regions that reveal the sound-absorbing material.

In at least one embodiment, a microporous membrane having a moderate to high water vapor permeability and high liquid water penetration resistance is disclosed. The microporous membrane may be used in building applications, including as or as part of a building wrap, a rain screen, a roofing underlayment, a flashing, a sound proofing material, or an insulation material. The microporous membrane may include at least one thermoplastic polymer, at least one filler, and at least one processing oil. The microporous membrane may be flat or may have ribs. The microporous membrane may include at least one scrim component. A method for forming the microporous membrane is also disclosed.

The invention relates to a partition wall which comprises a wall element and a stand device, wherein the wall element comprises a multiplicity of tubular bodies, each having a cavity, which are vertically aligned in the room. The wall element herein comprises spacer webs, wherein one of the spacer webs is in each case disposed between neighbouring tubular bodies of the wall element in such a manner that the tubular bodies are aligned so as to be mutually parallel and mutually spaced apart.

An underlay mat (10) for floor coverings, includes a polyurethane layer (14), a self-adhesive film (20) on the topside of the polyurethane layer (14) and which includes a carrier film (12), a layer of adhesive (22) applied to carrier film (12), and a mesh structure (24) made of fibers which is embedded in the adhesive layer (22), and a removable protective film (26) on the topside of self-adhesive film (20).

To provide a sound insulation sheet member which is excellent in sound insulation performance in a low frequency band and which has a compact configuration. A sound insulation sheet member 1 including a substrate 2 and a concavo-convex structure 3 placed on at least one surface of the substrate 2, in which the concavo-convex structure 3 is provided by repeatedly arranging a plurality of units each defined as a concavo-convex unit shape 4 including a linear convex portion 5, in one direction at substantially constant intervals on the surface of the substrate 2.

An object of the present invention is to provide a sound insulating sheet member that has high sound-insulating performance which exceeds mass law while being relatively light weight, that is highly flexible in design, excellent in versatility, and easy to manufacture so that productivity and economic efficiency can be improved, and a sound insulating structural body or the like using the same. The object thereof is achieved by using a sound insulating sheet member comprising at least a sheet having rubber elasticity and a plurality of resonant portions, wherein the resonant portions are provided in contact with a sheet surface of the sheet, each of the resonant portions including a base part and a weight part, and the weight part being supported by the base part and having a larger mass than the base part.

The present teachings generally relate to an acoustic panel including a backing layer, honeycomb core attached to the backing layer, a mesh layer attached to the honeycomb core, and a face sheet including a flexible acoustic fabric face sheet attached to the mesh layer. The acoustic fabric face sheet can provide improved sound dampening characteristics over, for example, a perforated face sheet, and at a lower manufacturing cost, weight, and a simplified manufacturing process. The acoustic fabric face sheet can be or include a flexible woven and/or knitted fabric including a polymer such as an aromatic polyamide that includes a meta-aramid fiber, or a fiberglass fabric.
