Aluminum Alloy Outward-opening windows

Dongcheng's outward-opening aluminum alloy windows direct all panel movement to the exterior of the building, leaving interior space entirely unobstructed when open. Heavy-duty stainless-steel hinges and multi-point locking hardware provide robust structural connection between sash and frame, delivering strong wind resistance and a high level of security in both the open and closed position.

The tight multi-layer sealing system seals effectively against wind, rain, noise, and thermal transfer when closed, while the outward-opening geometry promotes efficient natural ventilation even in strong prevailing winds. Optional opening limiters are available for high-rise installations, ensuring safe, controlled operation at elevation. The range is particularly well suited to high-floor residential bedrooms, hotel rooms, offices, and hospitals where interior space utilization and acoustic performance are priorities.
