Factory-direct custom glazing solutions tested to European Standards (EN 14351-1) for thermal performance, air tightness, and structural wind resilience.
Portugal’s construction and architectural sector is undergoing a profound transformation driven by stringent European Union decarbonization mandates and a thriving luxury real estate market. From the sun-drenched coastal estates of the Algarve (Quinta do Lago, Vale do Lobo) to urban historic restorations in Lisbon (Chiado, Avenida da Liberdade) and Porto (Foz do Douro), high-performance external aluminium French doors have become the preferred specification for tier-one architects and real estate developers.
Unlike traditional timber or standard PVC profiles, engineered thermal break aluminium French doors provide the structural integrity required to span expansive glass openings while resisting aggressive Atlantic marine climates. Under the Portuguese national building framework REH (Regulamento de Desempenho Energético dos Edifícios de Habitação), building envelopes must achieve strict overall thermal transmittance ($U_w$) values. Manufactured in Foshan, China—the global epicenter of aluminium extrusion—our systems integrate PA66GF25 polyamide thermal breaks, multi-chambered insulated profiles, and marine-grade Qualicoat powder coatings to fulfill every parameter mandated by Portuguese building codes.
Information Gain Key Metric: Our export-grade thermal break French door systems achieve certified overall thermal transmittance values as low as Uw = 1.1 W/m²K (when fitted with argon-filled Low-E triple glazing), comfortably surpassing Portugal's thermal performance threshold required for NZEB (Nearly Zero-Energy Buildings).
Portugal exhibits significant regional climate variations—from severe Atlantic wind-driven rain along the northern coastline to extreme solar radiation in the south. We engineer systems specifically tailored to each zone.
Southern Portugal experiences over 300 days of sunshine annually. Our southern coastal specification utilizes double/triple Low-E coated glass with Solar Heat Gain Coefficients (SHGC) controlled down to 0.28, significantly reducing interior air conditioning loads while preserving natural light.
Coastal properties face aggressive salt spray and high gust forces. We apply Qualicoat Class 2 / Seaside pretreatment powder coatings with an anodized base coat. Heavy-duty 6063-T6 extruded profiles resist wind loads up to Class C5 (EN 12210).
In high-density zones like Lisbon’s Baixa or Porto’s historic core, noise mitigation is paramount. Double EPDM perimeter gaskets combined with asymmetric laminated acoustic glass setups achieve sound insulation levels of up to Rw = 44 dB.
Every order exported to Portugal is supported by factory declarations of performance (DoP) and comprehensive laboratory testing reports under European norm EN 14351-1.

Window Wurx Industry Co., Ltd. (based in Dali Town, Foshan, China) brings over 30 years of global export experience directly to Portuguese distributors, general contractors, and architectural procurement agencies.
Every door profile is custom-extruded to match architectural drawings. We support custom two-tone finishes (e.g., Anthracite Grey RAL 7016 exterior to suit modern facades, combined with Traffic White RAL 9016 interior to match room design).
Operating 3 automated CNC cutting and assembly lines with 150+ skilled technicians allows us to process large-scale multi-unit commercial orders without sacrificing tolerance accuracy or missing strict project deadlines.
To withstand long-distance maritime transit from China to key Portuguese ocean terminals (Port of Sines, Port of Leixões, Port of Lisbon), every door frame undergoes 5-stage protective wrapping, rigid corner guards, and fumigation-free solid timber crating.
Essential regulatory, logistical, and technical insights for Portuguese architects, developers, and door importers.
Yes. Our thermal break external aluminium French doors are designed specifically to conform to Portugal’s REH (Regulamento de Desempenho Energético dos Edifícios de Habitação) and EU Energy Performance of Buildings Directive (EPBD). By pairing multi-chambered polyamide thermal breaks with Low-E double or triple glazing containing argon gas, our doors easily achieve the required U-value ($U_w$) ratings mandated across all Portuguese climate zones (Zone I1 to I3 for winter thermal performance and V1 to V3 for summer solar control).
All exported window and door systems carry full CE marking under EN 14351-1:2006+A2:2016. We supply formal Factory Declaration of Performance (DoP) documentation, glass thermal certification reports, Qualicoat coating guarantees, and structural wind/water laboratory test certificates required by Portuguese municipal authorities (Câmara Municipal) during final building sign-off.
For coastal projects in locations such as Cascais, Estoril, Sintra, Algarve, or Aveiro, we utilize Qualicoat-certified "Seaside" pre-treatment processes. This involves acid-etching pre-anodization followed by a minimum 60-80 micron thickness coating of super-durable fluoropolymer or polyester powder. Additionally, all exposed hardware, hinges, and fasteners are upgraded to Grade 316 Stainless Steel or marine-treated architectural zinc alloys to prevent galvanic and atmospheric corrosion.
We routinely ship FCL (Full Container Load) and LCL (Less than Container Load) orders directly to Porto de Leixões (Porto), Porto de Sines, and Porto de Lisboa (Lisbon). Production lead time standardly ranges between 25 to 35 business days following shop drawing sign-off. Ocean transit time from Foshan/Shenzhen ports to main Portuguese container hubs takes approximately 28 to 35 days.
Absolutely. We specialize in custom-engineered sizes including oversized double-leaf French doors with structural transoms or side lites up to 3.2 meters in height. We also offer internal Georgian bars, bonded surface muntins, or Crittall-style black metal grilles designed to match both traditional Portuguese pombalino architecture and ultra-modern minimalist villas.
