摘要:
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 double-walled panel for building includes a double-walled main body (1) defining an inner space and two opposite open sides, and being internally provided with a plurality of spacing boards (11) to divide the inner space into a plurality of chambers (12), and each of the chambers having two opposite open ends (121,122) at the two open sides of the main body; a working liquid stored in the chambers in the main body; and at least two sealing covers (3) for sealing the two open sides of the main body as well as the two open ends of each of the chambers. The double-walled panel may be used as a ceiling panel or a partition panel. The working liquid stored in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in putting out fire when the building is on fire.
摘要:
A ceiling tile of gypsum and cellulose fibers formed into a board by initially mixing the fibers and gypsum in a water-based slurry that is felted and thereafter pressed and dried with a desired board thickness, the dried board being processed to form a plurality of holes in a face thereof through at least the. majority of the thickness of the board, the collective volume of the holes being sufficient to reduce the weight of the board by at least 10% and increase the NRC exhibited by the board over that which would otherwise be found in a board of the same composition without such holes.
摘要:
A ceiling tile transmitter and receiver system having at least one transmitter/receiver device located in a ceiling panel either during or after the ceiling panel fabrication process. In one embodiment one or more pockets of variable size and shape are created on a surface of the ceiling panel during or after the ceiling panel manufacturing process and then a transmitter/receiver device, such as an RF antenna, is rigidly fixed in the pocket In another embodiment, the transmitter/receiver device is embedded in the front side (lower surface) of the ceiling tile and a "scrim" covering is placed over it to secure it in place. The transmitter/receiver device can also be embedded inside the ceiling tile or rigidly fixed on an upper, lower or side surface of the ceiling tile. The transmitter/receiver device can be encased on the front surface of the ceiling tile, where the transmitter adds to, or integrates into, the overall aesthetics of the ceiling tile. Various combinations of these embodiments can be used with a single ceiling tile. A high temperature resistant "place holding" structure that can withstand the ceiling tile treatments can be provided and later removed to allow the installation of the transmitter/receiver device.

Die Erfindung betrifft eine schallabsorbierende Wand- oder Deckenverkleidung mit poröser Schallschluckschicht (1) und schalldurchlässiger Abdeckung (2). Erfindungsgemäß ist die Abdeckung eine luftdurchlässige poröse Tapetenbahn (2) mit einem Flächengewicht von vorzugsweise mehr als 50 g/m², welche einen Strömungswiderstand von 10 bis 1500 Ns/m³ aufweist. Zwischen der Schallschluckschicht (1) und der Tapetenbahn (2) ist fernerhin ein Abstandshalter (3) angeordnet.
