Where is the KARON factory located and what does it manufacture?

Karon Window & Door Co., Ltd. operates a 10,000 m² standardized production facility in Songxia Industrial Park, Nanhai District, Foshan, Guangdong, China. We manufacture custom aluminium windows and doors, sunrooms, glass railings and shower enclosures.

Which international certifications do KARON products hold?

Our certification portfolio includes CE (EN 12150), US SGCC safety glazing, Australia AS 2208, New Zealand AS/NZS 2208 for single pane and laminated glass, Thailand TISI 965-2560 and 1231-2560, and Malaysia CIDB PPS certification. Production runs under an ISO 9001 quality management system.

Can you manufacture windows and doors to my architectural drawings?

Yes. Every order is engineered to your drawings or window schedule, including opening sizes, opening style, profile system, glass build-up, hardware and finish colour. Our engineers review drawings and confirm shop details before production.

What types of projects does KARON supply?

We supply private residences, premium villas, resort hotels, logistics offices and multi-unit developments. Recent projects include Kora Beach Resort Phuket with 672 units across 9 low-rise buildings and private residences in the USA, Greece and France.

What is the difference between thermal break and non-thermal break aluminium windows?

Thermal break profiles separate the inner and outer aluminium with an insulating polyamide strip, reducing heat transfer and condensation. They suit climates with heating or cooling demand and energy-code projects. Non-thermal break profiles are cost-efficient for mild climates, interior partitions and budget-sensitive projects.

Technical Compliance: Understanding CE EN 14351-1 Certification for Exterior Pedestrian Doorsets

In modern architectural procurement, sourcing exterior doors for European and international construction projects requires stringent adherence to harmonized building codes. CE marking under EN 14351-1:2006+A2:2016 establishes statutory compliance for external pedestrian doorsets without resistance to fire and/or smoke leakage characteristics. For procurement managers, real estate developers, and architects, working with a verified CE certified aluminium outside doors supplier ensures that structural integrity, safety glass standards (EN 12150), thermal insulation, and dangerous substances declarations are fully validated.

Extruded aluminium profile systems must be crafted from high-tensile 6063-T5 or 6063-T6 aluminum alloys, featuring wall thicknesses ranging from 2.0mm to 3.0mm depending on leaf height and wind-load exposure requirements. When evaluating supplier capabilities, inspecting factory production control (FPC) procedures, ISO 9001 quality management systems, and initial type testing (ITT) certificates provides non-negotiable risk mitigation against site installation failures.

Structural Engineering & Thermal Barrier Mechanics of Outside Doors

The primary engineering challenge in exterior aluminium door design is managing the thermal conductivity of metals while maintaining structural rigidity across massive architectural spans. Non-thermal break doors create a thermal bridge, causing rapid heat loss in winter, heat gain in summer, and internal surface condensation. Advanced thermal break aluminium outside doors solve this issue by inserting glass-fiber reinforced polyamide strips (PA66 GF25) between the inner and outer extrusions.

This multi-cavity construction decouples interior and exterior ambient temperatures, dramatically reducing overall frame U-values ($U_f$). When paired with warm-edge spacer bars, argon gas filling, and double or triple Low-E tempered glazing units (IGUs), these door systems achieve total U-factors ($U_w$) as low as 1.1 W/m²K—exceeding Passivhaus and strict European energy directives.

Industry Insight

2025–2030 Global Sourcing Trends in Architectural Outside Doors

Key technological shifts shaping commercial and luxury residential fenestration procurement.

Low-Carbon & Recycled Aluminum Extrusions

Global developers increasingly mandate green building credentials such as LEED and BREEAM. Leading suppliers utilize primary billet aluminium produced with hydropower or post-consumer recycled content to minimize embodied carbon footprints without sacrificing structural yield strength.

Integrated Biometric & Smart IoT Access Controls

Modern exterior entrance doors seamlessly merge heavy-duty security locks with smart access systems. Built-in fingerprint scanners, RFID keypads, facial recognition cameras, and motorized multi-point lock actuators are integrated into flush frame profiles during factory assembly.

Ultra-Slim Sightlines & Oversized Panoramic Panes

Architectural demand favours minimal visible aluminium frames with maximal clear glass area. Advanced structural glazing adhesives and hidden sash designs allow pivot doors up to 3 meters in height and bi-fold doors carrying up to 500kg per panel while operating effortlessly.

Procurement FAQ

Frequently Asked Questions by Overseas Buyers & Contractors

Essential answers regarding certification, engineering capability, thermal specs, and shipping logistics.

What specific standards guarantee the CE certification of your exterior aluminium doors? +

Our aluminium outside doors comply strictly with EN 14351-1 for external pedestrian doorsets, while the safety glass incorporated holds CE EN 12150 certification. Test reports cover air permeability (EN 12207), watertightness (EN 12208), resistance to wind load (EN 12210), and dangerous substance release declarations required for European Union building permit approvals.

How do thermal break exterior doors differ from standard aluminium profile doors? +

Thermal break aluminium doors feature a continuous structural polyamide insulation strip (such as PA66 GF25) separating the interior and exterior aluminium extrusions. This prevents direct heat conduction, significantly lowering the door’s U-value, eliminating interior condensation in cold weather, and reducing energy expenditure in air-conditioned environments. Non-thermal break doors are best suited for internal partitions or mild tropical climates.

Can you manufacture exterior doors according to custom architectural drawings and schedules? +

Yes, 100% of our production is customized. Our engineering team converts your architectural elevation drawings, window/door schedules, or CAD files into detailed factory shop drawings. We tailor opening mechanisms (pivot, bi-fold, lift-and-slide, double swing), profile wall thicknesses, surface finishes, glass specifications, and hardware brands (German GU, Hoppe, Siegenia, or custom hardware).

What international safety glazing certifications do your products carry? +

In addition to European CE compliance, our glass units hold US SGCC (Safety Glazing Certification Council) marks, Australian AS 2208 and New Zealand AS/NZS 2208 standards for toughened and laminated glass, Thailand TISI 965-2560 & 1231-2560 standards, and Malaysian CIDB PPS approval.

What measures are taken to ensure sea-freight transport safety for heavy exterior doors? +

Every door frame and sash is wrapped in protective PE film, corner-guarded with foam armor, and encased in fully closed fumigated plywood crates or steel-reinforced A-frames. Glazed units are separated with shock-absorbing cork pads to guarantee zero breakage during ocean transit and container unloading.

How do I request a preliminary quotation and engineering review? +
