Described herein is a building panel comprising a substrate and an odor and VOC reducing coating applied to the substrate, the coating comprising a blend of a first component comprising ethylene urea; a second component comprising silica; and a rheology modifier.

An acoustic housing, a light fixture, a suspended ceiling system, and a method of decreasing sound transfer from a light fixture in a suspended ceiling are disclosed. An acoustic hood for a light fixture in a suspended ceiling may include a partially enclosed space formed between a plurality of wall portions. A light fixture may include first and second layers that are coupled to one another and form a partially enclosed space. A suspended ceiling system may include the acoustic hood or light fixture. The method relates to disposing an acoustic housing spaced from the light fixture.

A building structure 1a, 1b, and 1c incorporates an outer wall 6 provided on a lower side of a sloped ceiling 2 in a slope direction, an opening part 5 formed in the outer wall 6, a box-shaped groove part 15 formed at a lower end of the sloped ceiling 2 along the outer wall 6 and having a lower opening 14 opened downward, and an attachment part 17 provided inside the groove part 15 and to which an upper end part of a light shielding material 16 that shields light incident on the opening part 5 is attached, wherein the groove part 15 is a ceiling-embedded type embedded in the sloped ceiling 2, and a lower end of a side plate of the groove part 15 on a side opposite to the opening part 5 is lower than a height of a lower surface of a frame 23 on an upper side of the opening part 5.

In one aspect, composite construction materials are described herein. In some embodiments, a composite construction panel comprises a substrate layer, a cover layer separated from the substrate layer by one or more spacers, and at least one mat disposed between the substrate layer and the cover layer, wherein the mat comprises at least one phase change material disposed in at least one phase change region.

A soundproofing structure comprises a jacket having an external surface and an opposite internal surface defining an inner compartment. A resilient and deformable soundproofing material is contained within the Inner compartment and engages the internal surface. Constricting elements are mounted to the jacket for constriction of the jacket to provide inner surface pressure against the soundproofing material for compression thereof. The constricting elements are releasable for selectively releasing inner surface pressure against the soundproofing material for expansion thereof against the inner surface. The soundproofing structure defines a size that is selectively modifiable by selective releasing of the contacting elements.

Described herein is a building panel comprising a body comprising a first fibrous material comprising inorganic fiber, a non-woven scrim coupled to the body; and wherein the non-woven scrim has a thickness ranging from about 8 mils to about 20 mils.

A method for manufacturing acoustical elements, includes providing a first fibre component in a form of mineral wool and a second fibre component in a form of bicomponent fibres having a core with a thermoplastic outer layer, mixing the first fibre component and the second fibre component, for provision of a mixture, shaping the mixture into single layered tile shaped elements whereby the mixture is compressed with a compression ratio to a compressed state, and fixating the single layered tile shaped elements in the compressed state for obtaining the acoustical elements.

A dynamic acoustic locking ceiling baffle and a dynamic acoustic locking ceiling system, that includes a single piece of material folded into acoustic locking ceiling baffles, using locking pieces and locking mechanisms, to quickly and easily install the acoustic locking ceiling baffle onto construction ceiling hangers to provide an aesthetically pleasing image, along with a reduction in unwanted noise or room acoustics.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.

A modular dynamic acoustic system for use in connection with an indoor environment includes a movable panel array, a support structure, and a plurality of suspension members. The movable panel array includes a plurality of panel members, each of which including a body defining at least one edge, at least one hinge positioned along the at least one edge, and at least one mounting structure. The panel members are operably coupled with at least one adjacent panel member via the at least one hinge. Each of the plurality of suspension members is operably coupled with the support structure and the at least one mounting structure of one of the plurality of panel members to secure the movable panel array to the support structure. Each of the suspension members is movable to modify a configuration of the movable panel array.
