China Top Aluminium Back Doors Manufacturer & Exporter

The global construction industry is undergoing a paradigm shift towards materials that balance structural integrity with environmental sustainability. Aluminium back doors have emerged as a cornerstone in modern architectural design, particularly in North America and coastal Caribbean regions, where resistance to corrosion and high-velocity hurricane zones (HVHZ) is non-negotiable. As a leading manufacturer, we recognize that a "back door" is no longer just a secondary entry point; it is a critical component of a building's thermal envelope and security perimeter.

Registered in 2017, Ningbo Novax Building Materials Co., Ltd. has established itself as a technological vanguard. With 9 years of specialized industry experience and 6 years of global export proficiency, our operations are optimized for high-volume commercial projects and bespoke residential developments. Our annual export capacity reflects our dominance in the North American and Caribbean markets, where our NFRC AS2047 certified systems meet the most stringent building codes.

Last year, our R&D center introduced 85 new window and door models, driven by the needs of coastal commercial projects and high-end residential developers. Our strategic partnership with 1,100 material suppliers ensures that we never compromise on the quality of anodized surface finishes or heavy-duty thermal profiles.

Q1: Why choose Aluminum over uPVC for back doors?
A: Aluminum offers superior structural strength, allowing for larger glass spans and slimmer profiles. Unlike uPVC, it does not warp under UV exposure, making it ideal for tropical and high-altitude climates.

Q2: What certifications are necessary for the North American market?
A: Most states require NFRC (National Fenestration Rating Council) ratings for energy and AS2047 or AAMA certification for structural and water penetration performance. Novax products are engineered to exceed these standards.

Q3: How does the "Thermal Break" technology actually work?
A: It’s a process where a reinforced polyamide bar is placed between the interior and exterior aluminum profiles. This breaks the conductive path of the metal, preventing "sweating" and heat loss.
