The 150 Non-Thermal Break Series Middle-slot Fixed Window is a functional unitized curtain wall system designed for modern industrial and public building facades. It integrates ventilation features into the central structure of a fixed window unit, effectively balancing aesthetic simplicity with localized airflow requirements. The window unit utilizes 150 Series thickened aluminum profiles (wall thickness 2.2mm), with a centrally positioned horizontal ventilation slot (width 80-150mm) that can be equipped with optional insect screens, filter cotton, or manually adjustable louvers to provide basic air exchange without altering the overall window structure.

The system employs a combination of structural bonding and mechanical fixing: glass and profiles are bonded with silicone structural adhesive to form an integral load-bearing unit, while concealed clip-in systems along the edges ensure long-term airtightness. The ventilation slot is designed as an independent modular component, allowing for on-site disassembly and maintenance. Standard glazing is 10mm tempered insulating glass (upgradable to triple-glazed or laminated configurations), with profile surfaces treated with fluorocarbon coating to meet industrial environmental durability requirements.

This product is suitable for applications requiring high facade integrity, such as logistics centers, data center exteriors, and sports venue envelopes. It maintains the visual uniformity of large-area glass curtain walls while avoiding the structural weaknesses and cost increases associated with adding local opening sashes. Installation utilizes unitized pre-assembly technology, with three-dimensionally adjustable connectors allowing for ±10mm installation tolerance compensation. It represents an innovative window solution within the non-thermal break system, harmonizing aesthetics and functionality.
