A multi-pane glass unit includes a first outer glass pane and a second outer glass pane facing each other, a first inner glass pane between the first outer glass pane and the second outer glass pane, a first spacer located between the first outer glass pane and the first inner glass pane, and a second spacer located between the second outer glass pane and the first inner glass pane.

Provided is an apparatus for manufacturing a multi-pane glass unit. The apparatus includes: a first plate configured to hold a first glass pane; a second plate configured to hold a second glass pane such that the second glass pane faces the first glass pane; and a conveyer including a first portion configured to convey the first glass pane onto the first plate and a second portion configured to convey the second glass onto the second plate.

A noise management system for a window includes an active noise control (ANC) module and a passive sound absorbing module. The ANC module is disposed in or adjacent a ventilation channel of the window and configured to substantially cancel low-frequency noise entering the ventilation channel. The passive sound absorbing module is disposed in or adjacent to the ventilation channel and configured to absorb both high-frequency noise entering the channel and harmonic sounds generated by the ANC module.

A glazing having enhanced acoustic performance, includes at least one transparent substrate including, on at least one of its faces, an array of transparent piezoelectric transducers and a plurality of resonant electrical circuits, each transparent piezoelectric transducer being connected to a single resonant electrical circuit such that the substrate forms a transparent metamaterial.

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.

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 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.

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.
