1. Excellent Energy-Saving Performance EDUN narrow frame sliding doors adopt advanced thermal break aluminum technology, with high-quality insulated glass filled with argon and tight EPDM sealing strips. The super warm edge strip sealing reduces heat transfer, making your home warm in winter and cool in summer, effectively reducing energy bills by 20%. They fully meet US energy efficiency requirements and help you save money every month. All products use Austrian Tiger Powder coating, which is eco-friendly and durable.
2. Reliable Safety Certification Our products have passed ASTM safety standards (including ASTM F842 and ASTM F1643), which are widely recognized in the US. The narrow frame is made of high-strength 6060 T66 aluminum alloy, and the glass is automotive-grade tempered safety glass—anti-scratch, anti-impact, and can resist strong winds up to level 8. We also have 128 national patents, and our products are insured by Ping An Insurance, providing all-round safety protection for your family.
3. Trendy & Practical Design Following the US minimalist trend, EDUN narrow frame sliding doors have a slim profile, maximizing natural light and your view. They adopt frame-wrap-sash structure and imported hardware accessories, which are easy to slide and have passed 500,000 times of durability testing. They don’t take up extra space and fit all modern home styles—apartments, houses, or villas. We provide classic colors such as white, black and dark gray to match your home decoration.
