Soundproof glass door
Acoustical glass door:
* All-around seal
* STC of 35 dB
* Ensures privacy
An acoustical sliding door has an all-around seal said to keep sound in (and out) to ensure workplace privacy. In testing, the door
keeps sound in/out to 35 dB. Using soundproof glass and seals on four sides, the door's rail system is built in linear layers. When
closing, a profile catches the door in between two sealing profiles/gaskets. The bottom uses a drop seal, a small metal stop on the
bottom of the door with a bottom gasket. When the door is fully closed, the drop seal is engaged, providing additional soundproofing. The door can be integrated in all of the company's Living Walls' systems, including Horizon, String2, Panorama, and Metaline.

Improved window spacer
TGI-Spacer M with Wire is said to improve the overall thermal and structural
performance, reduce the risk of condensation, and enhance the appearance of
window systems. Using a hybrid composition, the product is a cold bendable,
warm-edge spacer bar comprising a thin, low-conductivity stainless steel, a
spring-steel wire, and an engineered thermoplastic. By reducing heat transfer
at the edge of the glass, the product reportedly minimizes the risk of interior
condensation, improving thermal comfort for occupants.
