Hollow louvered glass

Hollow Louvered Glass (also called Insulated Glass with Built-in Louvers) is a high-functional integrated glass unit that combines the thermal insulation of hollow glass with the flexible light/shade control of built-in louvers—redefining versatility, privacy, and energy efficiency in modern architecture, solving the flaws of traditional glass (fixed light transmittance, poor privacy control, and need for external blinds/curtains that are easy to dirty or damage). Its core advantage lies in the innovative integrated structure: two or three panes of glass (float, tempered, or Low-E coated) form an airtight hollow cavity (12–20mm) separated by aluminum spacers (filled with desiccant to prevent condensation), with aluminum alloy louvers (adjustable angle 0–180°) installed inside the cavity; the louvers are controlled by magnetic transmission (external handle or remote control) to avoid drilling holes in the glass (ensuring airtightness). This design delivers a 15–20 year service life (on…
