Designed to support large glass panels, the reinforced aluminum frame ensures stability and minimizes sagging or operational issues over time.
Modular frame and adjustable rollers simplify on-site assembly, reducing labor costs and project timeline.
Thermal break profiles combined with insulated glass reduce heat loss, helping buildings comply with energy codes and lower operational costs.
Special surface treatments and powder coating prevent oxidation, ensuring long-term durability in coastal or high-humidity environments.
Durable rollers and sealed tracks ensure smooth sliding and minimal maintenance, reducing long-term service costs.
We partner with:
Architectural firms and design studios
Construction contractors and real estate developers
Distributors and project collaborators
Our team offers expert technical guidance, detailed CAD drawings, and tailored system solutions to ensure every window meets project requirements, performance standards, and local regulations.
The insulated polyamide strip separates interior and exterior aluminum sections, reducing heat transfer and improving insulation performance.
Yes. The heavy-duty roller system is designed to carry large glass panels while maintaining smooth sliding performance.
The structure is engineered for high wind resistance and strong sealing performance, making it suitable for coastal and high-wind areas.
Double-glazed or Low-E insulated glass units are recommended to maximize thermal efficiency and sound reduction.
