ECO98 internal and external flush/dual internal opening system windows
◇ Ultra high precision aluminum material
6060-T66 Huajian aluminum profile with 44mm insulation structure; Dual optimization of compressive performance and stability, reducing thermal conductivity.
◇ Gradient sealing
The three layer composite sealing system is suitable for multi climate environments, blocking noise and heat exchange; Maintain a constant temperature and silent indoor environment.
◇ Anti fall structure
The dual internal fan design combined with limit hinges reduces the risk of falling from high altitude, while balancing ventilation safety and operational convenience.
◇ Invisible security
The hidden hardware system has a built-in child lock function, eliminating hidden dangers of exposed parts and adapting to the protection needs of multiple home scenarios.
◇ Transparent perspective
The 6cm extremely narrow frame section is designed with high transparency glass yarn, expanding the lighting surface by 15% and providing unobstructed ventilation for a wider field of view.
◇ Convenient cleaning
Internally and externally flush without dead corners design reduces dust accumulation areas, coupled with narrow frame structure, significantly improves daily wiping efficiency.
