The present disclosure relates to interior material attachment structure with wall attachment part bolt grooves, including: binding protrusions formed at the outermost part of the interior material attachment structure in order to attach the metal interior material; and connection part grooves formed adjacent to the binding protrusions in order to connect the plurality of interior material attachment structures to each other.

An architectural fixture assembly includes a first beam and a second beam which are configured to be coupled together. The first beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the first beam include notches extending upwardly from a bottom end of the first beam. The second beam includes a bottom side and first and second sides extending from the bottom side. The first and second sides of the second include notches extending downwardly from a top end of the second beam. The first and second beams may be coupled together by engagement of the notches of the first beam with the notches of the second beam.

Described herein is a flame-retardant building panel comprising a body having a first major surface opposite a second major surface, an inorganic coating atop the first major surface, the inorganic coating being optically transparent and flame retardant and comprising a silicate compound; and wherein the inorganic flame retardant coating is substantially transparent such that the first major surface of the body is visible through the inorganic coating.

Acoustic panels, grids for acoustic panels, suspended ceiling systems and a method for producing an acoustic panel, especially a man-made vitreous fibre (MMVF) panel, having a first major face and an opposite second major face, with the first major face comprising a facing with a surface coating. To provide high light reflection the coating comprises microspheres.

The present disclosure relates generally to fiberglass panels, for example, suitable for acoustic ceiling surfaces. The present disclosure relates more particularly to an acoustic panel having a top surface, a bottom surface, and a perimeter edge. The acoustic panel includes a layered fiberglass panel body including a core fiberglass layer and a high density fiberglass layer secured to a lower face of the core fiberglass layer. The high density fiberglass layer has a higher density than the core fiberglass layer. The layered fiberglass panel body includes an outward projection at the perimeter edge of the acoustic panel that is formed by the high density fiberglass layer and a portion of the core fiberglass layer. A supporting perimeter frame extends around the outer edge of the core fiberglass layer, and the outward projection of the layered fiberglass panel body extends outward beneath the supporting perimeter frame.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

A method and apparatus for minimizing tissue adhesion in a tissue of a subject includes applying light, to the tissue, that reduces at least one adhesion marker in the tissue, the light having wavelengths in at least one of a first wavelength range of 730-770 nm and a second wavelength range of 930-970 nm, wherein the at least one adhesion marker includes at least one of a transforming growth factor beta 1 (TGF-β1), a vascular endothelial growth factor, (VEGF), and a collagen alpha-1(I) chain (COL|α|), and wherein the light is free of wavelengths that increase the at least one adhesion marker.

A construction panel contains at least one insulation layer, at least one active thermal layer containing at least an electrical heating and/or an electrical cooling element, and a connector for connecting the at least one active thermal layer to a source of electrical current. The active thermal layer is preferably an active heating or cooling layer.

An architectural fixture assembly including a generally U-shaped first beam having a bottom side, a first side, a second side, and a first end. Interior surfaces of the first, second, and bottom sides of the first beam define an interior portion. A connector includes a plate, and a connection key extending away from the plate. The interior surfaces of the first and second sides each include a generally V-shaped alignment notch disposed generally adjacent to the first end of the beam. The connection key includes a pair of generally V-shaped sides disposed on opposite sides of the connection key, and each generally V-shaped side is configured to slidably engage one of the generally V-shaped alignment notches.

The disclosure provides a coating composition for improving the sag resistance of a fibrous panel, the composition including 10 to 100 wt. % inorganic binder, based on the total weight of the dry coating, wherein the inorganic binder includes a borate salt and at least one of an alkali metal silicate or an alkaline earth metal silicate, and the inorganic binder is water soluble. Further provided are fibrous panels having a backing side and an opposing facing side including the coating of the disclosure, and methods of preparing same.
