1. Ventilation Without Compromise – Fresh Air, No Insects
The glass sash opens inward while the screen stays in place, keeping mosquitoes, flies, and dust out. Enjoy fresh air all day without the usual insect problem.
2. Integrated Design – No Separate Screen Frame Needed
Unlike traditional setups that require a separate screen frame, this window integrates the screen directly into the system. It saves installation time, reduces hardware complexity, and gives a cleaner look inside and out.
3. Inward Opening – Safe for High-Rise, Space-Saving
The glass sash opens inward, so it never protrudes outside the building. Ideal for high-rise apartments, narrow balconies, and restricted facades. Cleaning the outer glass is easy – no leaning out.
4. Removable Screen – Easy Cleaning and Maintenance
The screen sash can be easily opened or removed, giving full access to the outer glass. No climbing, no professional help – routine maintenance is quick and safe.
