Explore our top-tier export-grade thermal break aluminum entry systems, engineered to exceed global structural, thermal, and acoustic metrics.
Established in 2017, Foshan Primeval Doors Industry Co., Ltd. operates from a modern manufacturing facility of 12,000 m². Backed by 11 years of industry engineering experience and 5 years of international export trade, the company generates an annual export revenue of USD 8,500,000.
Quality control is strictly enforced through systematic IQC-IPQC-FQC inspection procedures along with rigorous thermal conductivity and salt-spray corrosion testing. A skilled QC team of 22 inspectors oversees every step of the production process. Supported by 420 trusted supply chain partners, our trade background covers direct OEM export and private-label customization, serving primary markets in Australia, New Zealand, and North America.
Our client base consists mainly of residential building supply importers, architectural designers, and regional wholesalers. Driven by continuous innovation, our R&D group of 38 engineers introduced 75 new entry door products last year. Customization options include custom frame depths, double-glazed decorative glass inserts, powder-coated color palettes, and heavy-duty weatherproofing seals.
Standard aluminum profiles possess high thermal conductivity ($\lambda \approx 160-200 \text{ W/m}\cdot\text{K}$), leading to massive heat transfer, interior condensation, and elevated HVAC energy expenditure. Foshan Primeval Doors engineered high-performance thermal break entry doors to resolve this thermal bridge by introducing a structural, low-conductivity barrier within the extruded profile.
Our frames integrate 24mm to 34mm Technoform Polyamide PA66 reinforced with 25% glass fiber (PA66-GF25). This composite matches the coefficient of thermal expansion of aluminum profiles ($2.3 \times 10^{-5}/\text{K}$), preventing structural delamination or shear failure across extreme temperature cycles ($-40^\circ\text{C}$ to $+80^\circ\text{C}$).
By pairing PA66-GF25 structural breaks with Argon-filled triple-glazed Low-E IGU (Insulated Glass Units) featuring warm-edge spacers, our entry systems achieve exceptional total assembly U-factors down to $0.8 \text{ W/m}^2\text{K}$, aligning seamlessly with Passive House (Passivhaus) standards.
| Profile Engineering Configuration | Thermal Conductivity ($\text{W/m}\cdot\text{K}$) | Average Frame U-Factor ($U_f$) | Acoustic Attenuation (STC Rating) | Structural Deflection Limit |
|---|---|---|---|---|
| Standard Non-Thermal Aluminum | 160.0 - 200.0 | 5.8 - 6.5 W/m²K | STC 24 - 27 | L/175 |
| Standard uPVC Profile System | 0.17 - 0.25 | 1.8 - 2.2 W/m²K | STC 28 - 32 | L/150 (Structural Creep Risk) |
| Primeval PA66-GF25 Thermal Break (Standard) | 0.30 (Insulation Core) | 1.4 - 1.8 W/m²K | STC 38 - 42 | L/250 |
| Primeval Aerogel-Infused Thermal Break (Ultra) | 0.015 - 0.020 (Core) | 0.75 - 1.0 W/m²K | STC 45+ | L/300 (High-Rise Grade) |
Our 12,000 m² Foshan complex leverages fully automated CNC machining centers, automated profile cutting, double-corner crimping, and computerized QA monitoring. We maintain absolute precision tolerance within $\pm 0.2\text{mm}$ across structural entry frame dimensions.






















Navigating international construction regulations requires absolute material compliance. Primeval Doors designs and tests fenestration products to satisfy rigorous overseas standards.
Certified air infiltration, water penetration resistance (up to 600Pa), ultimate strength structural testing, and safety glazing compliance under AS1288 for Oceania construction standards.
High-Velocity Hurricane Zone (HVHZ) compliance. Tested against cyclic wind pressure dynamics ($\pm 100 \text{ PSF}$) and large missile impact resistance (ASTM E1886 / E1996).
Full declaration of performance for thermal transmittance, acoustic rating, air permeability (Class 4), and watertightness (Class E1050) across EU member territories.
Our exterior aluminum surfaces undergo fluoropolymer PVDF coating processes conforming to AAMA 2605 specifications or 25-micron anodic oxidation treatments. Tested in 3,000-hour continuous salt-spray chambers, our entry systems withstand aggressive coastal microclimates, preventing chalking, blistering, and marine salt degradation.
Different building typologies mandate tailored structural, thermal, and security characteristics. Primeval Doors delivers domain-specific engineering frameworks:
Ultra-narrow sightlines, concealed heavy-duty 3D adjustable hinges, and integrated multi-point motorized locking systems. Seamlessly blends architectural elegance with intruder resistance and extreme thermal insulation.
Integrated 15N low-resistance panic exit hardware, smart access control interfaces (RFID, Biometric), and commercial-grade thermal break profiles capable of handling continuous cyclic traffic loads.
Triple-seal EPDM gasket arrays, quadruple glazing configurations with Low-E thermal coatings, and aerogel core thermal breaks engineered specifically to eliminate thermal bridging in Net-Zero projects.
Overseas builders, developers, and wholesale distributors require reliable supply chain timelines, minimal defect rates, and transparent shipping protocols. Direct sourcing from Foshan Primeval Doors optimizes your project budget while securing structural grade compliance.
From initial CAD/BIM architectural shop drawing approvals to custom extrusions, specialized powder-coating colors, and custom glass inserts (frosted, tinted, bullet-resistant), our 38 R&D engineers deliver complete product customization.
Every finished door and window module is protected by multi-layer EPE foam, blue protective surface film, custom wooden crates, and steel-strapped palletization. This strategy guarantees zero transport damage during ocean transit.
As global carbon neutrality targets tighten and smart building automation matures, Primeval Doors leads innovation across three technological pillars:
Integrating nano-porous silica aerogel within the polyamide thermal cavity to achieve thermal insulation values equivalent to solid timber while retaining slim structural aluminum frames.
Embedding facial recognition, 3D palm vein sensors, and smart home protocol nodes (Matter, Zigbee, Z-Wave) directly into thermal break entry door frames without creating thermal leaks.
Developing Building-Integrated Photovoltaic (BIPV) glass options for entry door sidelights, coupled with low-carbon recycled aluminum billets smelted using renewable hydro-power.
Clear answers to crucial engineering, operational, and commercial procurement queries for international trade clients.
