I recently worked on a project using etched glass with a custom sandblasted design, significantly enhancing the ambiance of the office.

Acoustic performance is a key consideration, particularly in areas requiring noise reduction. The thickness of the glass, the type of glass (laminated glass offers better sound insulation than single-pane glass), and the incorporation of an air gap between panes (in double or triple glazing) all significantly influence sound transmission. Using laminated glass with a special interlayer designed for sound dampening greatly improves performance. The air gap within double or triple glazing systems acts as an acoustic buffer, minimizing sound penetration. In a recent project for a recording studio, we implemented a multi-layered glazing system, significantly reducing external noise pollution. Calculating sound transmission class (STC) ratings helps specify the optimal glazing system for different noise levels.

Ensuring the energy efficiency of interior glazing involves carefully selecting appropriate glass types and incorporating strategies for heat control. Low-E coatings, as mentioned earlier, are crucial for reducing energy loss. The use of insulating glass units (IGUs), consisting of multiple panes with an air or gas-filled space between them, significantly improves thermal insulation. The selection of gas fill (argon, krypton, or xenon) within the IGU further enhances energy performance. Proper sealing of the glazing system is also essential to prevent air leakage. In my work, I always analyze the building’s climate and orientation to determine the optimal glazing specifications, maximizing natural light while minimizing heat gain or loss. For example, in a south-facing office, we might choose a low-E coating with a higher solar heat gain coefficient (SHGC) to maximize solar heat gain in winter while minimizing it in summer.
