A double glazing insulation system of the present invention is characterized by including: double glazing having a chamber formed between a pair of glass windows, a bead entrance through which air and a plurality of beads enter and exit the chamber, and an air entrance through which air enters the chamber; a storage tank for storing the plurality of beads; a bead flow pipe guiding the plurality of beads such that the beads flow; an air exhaust pipe guiding the flow of air discharged from the storage tank; an air flow pipe guiding the flow of air entering and exiting through the air entrance; and a main blower which sucks air of the chamber through the air flow pipe or through the air exhaust pipe, thereby filling the chamber with the plurality of beads or discharging the same from the chamber.

A sound proofing window system for use with an acoustic door is disclosed. The system includes 2 fully decoupled acoustic reveal formed between 2 acoustic windows, thereby providing a higher level of sound proofing than is achievable with existing art. A decoupled acoustic reveal means that there is no path of contact between the two acoustic windows that is unbroken by soundproofing material. Further, the acoustic windows may be positioned fully or partially outside the thickness of the door to increase the air gap. Prior art systems may attempt to partially decouple the acoustic reveal. A windowed standard 1.75 inch acoustic door according to the present invention provides an STC rating of 56-57, which is far superior to the 35-47 STC rating comparable prior art. The STC rating of the present invention on a 5 inch thick door is estimated at 64 compared to 54 using conventional technology.

The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four-sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

A sliding window to close off an open surface in a wall separating the inside from the outside. The window includes an opening panel, a frame and a passive acoustic silencer. The silencer includes two parallel and acoustically absorbent slides extending in a median plane normal to the open surface. One slide is attached to the opening panel and the other slide is attached to the frame. The movement of the opening panel relative to the frame creating, between the slides, a slit having a thickness equal to the window opening. Also, a system of windows to acoustically damp between the inside and outside of an open space in a wall.

A wall panel arrangement is designed for use in retrofitting a wall panel system provided with at least one pair of frame members having inwardly facing flat walls for retaining at least one existing glass panel therebetween. The wall panel arrangement includes an add-on glass wall panel and panel mounting structure configured with at least one receiving strip constructed with a planar body having an outer surface secured to one of the inwardly facing flat walls of the frame members in spaced relationship to the existing glass panel. The body also has an inner surface provided at opposite edges thereof with a pair of flexible resilient wall panel retaining elements extending therefrom and converging towards each other to define spaced apart retainer ends which are frictionally engageable with the opposed faces of the glass wall panel adjacent one of the opposed sidewalls thereof.

Attenuators are introduced that offer quiet, enhanced sound quality for interior of enclosures than previous devices. An acoustical rating system for the levels of sound propagation through glass windows/windshields is introduced for the building and construction industry. Just as windows and insulation have an R-value to define the temperature energy efficiency of the interior of a room, an A-Rating system would define the acoustical energy efficiency of an enclosure space. In the summer, the higher the R-value, the less cool air that escapes a room through a window (and the less heat that penetrates into the interior), thus keeping the room cooler with less energy. Similarly, the higher the A-Rating of a window, the less noise that propagates through, maintaining lower levels of sound in the interior of an enclosure, creating a more harmonious, acoustically energy efficient room for enhanced health, preventing sleep interference, speech interference, and maintaining adequate levels of safety according to EPA and OSHA standards. The A-Rating system can help set standards for bearable and unbearable windows for a particular house, building, shopping store, restaurant, vehicle-cabin, fuselage cabin, locomotive/train/subway cabin, hotel, apartment, airport, library, museum, or any other enclosure, for a particular area or jurisdiction.

The present invention discloses a vacuum glass middle support placing system that includes a glass plate placing station, a middle support placing station, a vacuum sealing station, a pallet and a conveyor. The pallet is directly conveyed by the conveyor to transfer it among the stations and the glass plate is placed on the pallet at the glass plate placing station. The pallet includes a supporting face that is matched with a surface of the glass plate and a glass plate positioning structure. A magnetic attraction surface array made of permanent magnets and corresponding to the middle supports to be placed on the glass plate is arranged on the supporting face.

A roll of energy-efficient laminate substrate is described. The energy-efficient fenestration assembly includes: (1) a performance film having at least one energy-efficient property; (2) a supporting film mechanically supporting said performance film; and (3) wherein said performance film is laminated and rolled with said supporting film to form said roll of said laminate energy-efficient substrate.

A glazing includes at least two glazed panels, which form a cavity between them, and at least one stack of resonators positioned in the cavity, wherein the at least one stack of resonators includes at least two resonators of different length, the resonators of the at least one stack having a longitudinal axis and being stacked along a stacking axis perpendicular to their longitudinal axis.
