Specifically custom-engineered for Berlin residential villas, commercial entrances, and urban renovation developments requiring strict thermal efficiency and anti-burglary protection.
The Berlin metropolitan region presents a rigorous testing ground for exterior entry doors. Characterized by freezing Central European winter temperatures (falling below -10°C), wet autumn shoulder seasons, and dense urban noise corridors, building envelopes in Germany are governed by strict energy efficiency standards. The German Building Energy Act (Gebäudeenergiegesetz - GEG) mandates stringent overall thermal transmittance thresholds ($U_d$ values) for exterior building components. Importing double glazed aluminum entry doors from China for Berlin real estate developments requires direct alignment with these European norms, combining low-emissivity (Low-E) glass technology, advanced multi-chamber thermal breaks, and certified burglary resistance.
Foshan Aluvoy Entry Door Systems Co., Ltd. delivers factory-direct engineering tailored specifically to Berlin’s climatic conditions and architectural regulations. By combining high-grade 6063-T6 extruded aluminum profiles with multi-cavity polyamide (PA66 GF25) thermal barrier strips, our double glazed entrance doors eliminate thermal bridging, preventing indoor condensation while reducing space heating losses in cold Brandenburg winters.
Utilizing 24mm to 34mm glass-fiber reinforced polyamide insulation strips to achieve frame thermal conductivity values that meet demanding German GEG standards.
Equipped with German-engineered multi-point locking gear, anti-pry hooks, hardened steel drill protection plates, and laminated safety glass (VSG).
Dual EPDM weather-stripping gaskets combined with asymmetric double glazing units effectively damp urban noise in high-density Berlin zones.
Thermal insulation in entry doors is quantified by the $U_d$ value ($W/m^2K$). The lower the numerical value, the higher the thermal resistance. Under current German GEG regulations, standard replacement exterior doors must achieve a maximum $U_d$ value of 1.3 $W/m^2K$, while low-energy Passive House (KFW Efficiency House 40) projects demand $U_d$ performance as low as 0.8 $W/m^2K$.
To exceed these benchmarks, Aluvoy integrates advanced double and triple glazing units into our aluminum door profiles. Our standard double glazed setup utilizes 6mm Low-E toughened safety glass (ESG) + 16mm Argon Gas spacer + 6mm clear toughened safety glass. Warm-edge spacer bars (TGI/Swisspacer) are applied along the perimeter to minimize linear thermal bridges ($Ψ$-value) around the glass edge.
Our insulated glass units (IGU) are filled with 90% concentration Argon gas sealed via automated dual-seal polyisobutylene (PIB) and structural silicone. This layer curtails radiant heat loss during Berlin's sub-zero winter spells, maintaining warm interior frame surface temperatures.
Profile surfaces undergo multi-stage chromate-free pre-treatment followed by Qualicoat-certified AkzoNobel powder coating. This ensures complete protection against atmospheric humidity, UV radiation degradation, and urban micro-particles without chalking or fading over 20+ years.
The following performance matrix contrasts Aluvoy’s engineered double glazed aluminum entry door configurations against standard European building requirements (DIN standards):

From historic Altbau facade restorations in Charlottenburg to contemporary residential developments in Pankow, Aluvoy provides tailored structural entry solutions.
In high-end residential quarters, security and architectural prestige are paramount. Aluvoy custom manufactures large-format grand pivot doors and heavy-duty double swing entry doors up to 3.0 meters in height. Featuring concealed 3D-adjustable hinges, biometric fingerprint scanners (Ekey compatible), and dual-tone powder coating (RAL 7016 Anthracite exterior / RAL 9016 Traffic White interior), these systems harmoniously blend safety with modern luxury.
Commercial entranceways experience high foot-traffic volume demanding robust mechanical hardware and barrier-free (ADA compliant) low thresholds under DIN 18040 standards. Our commercial double swing glass doors feature heavy-duty overhead door closers, electric strike locks integrated into building management systems (BMS), and anti-panic push bars (EN 1125), ensuring smooth egress and ingress under intense operational use.
Berlin’s historic apartment blocks often feature arched door openings and distinct heritage proportions. Aluvoy’s CNC bending and custom framing capabilities allow factory fabrication of arched double aluminum doors with authentic decorative transom windows. These units preserve the historical streetscape aesthetic while upgrading building performance from single-glazed drafts to modern RC2/GEG compliant thermal efficiency.
For housing developers and general contractors managing multi-unit residential contracts, cost-efficiency and unit uniformity are key. Aluvoy supplies standardized double glazed thermal break aluminum entry door packages shipped direct to site, complete with pre-drilled frame fixings, key-alike cylinder options, and fully assembled sub-frames for rapid, low-labor site installation.
Procurement preferences in Berlin are shifting rapidly driven by state climate neutrality goals (Berlin Climate Protection and Energy Transition Act) and evolving consumer demands:
By sourcing directly from Foshan Aluvoy Entry Door Systems Co., Ltd., Berlin importers and general contractors save up to 35-45% in procurement costs compared to local European fabricators, without compromising on EN certifications, hardware quality, or thermal performance.
Established in 2005, Foshan Aluvoy Entry Door Systems Co., Ltd. operates a state-of-the-art 20,000 m² manufacturing hub engineered specifically for high-precision international exports.
Managing door procurement from China to Germany requires seamless project coordination. Aluvoy follows a proven 6-stage engineering process engineered to eliminate site errors and customs delays:
Submit your door schedule, elevation plans, and thermal target requirements ($U_d$ values). Our technical team reviews local German building code specs.
We issue 2D/3D CAD shop drawings detailing profile cross-sections, thermal breaks, anchoring points, threshold details, and glass specs for sign-off.
Upon CAD approval, profile cutting, automated CNC slotting, thermal strip insertion, corner crimping, and glazing are performed under ISO 9001 quality controls.
Doors are pre-assembled in our factory to inspect locking mechanism smooth operation, air seal tightness, and dimensional accuracy prior to packing.
Units are wrapped in protective film, corner-protected, and packed into custom plywood crates designed for fork-lift handling and container loading.
Containers are shipped via direct maritime routes to Hamburg or Bremerhaven port (approx. 28-32 days transit), followed by rail/truck transport direct to your Berlin jobsite.
Clear, direct answers regarding certifications, thermal ratings, shipping, and customization options.
Yes. All Aluvoy double glazed aluminum entry door systems exported to the European Union carry authentic CE marking under EN 14351-1. We supply the complete Declaration of Performance (DoP) documentation, testing reports for wind load, watertightness, air permeability, and thermal transmittance values required by German building authorities (Bauamt).
Our doors utilize wide multi-cavity polyamide thermal barrier strips (PA66 GF25) separating the exterior and interior aluminum extrusions. Combined with 28mm-36mm double glazed Low-E units filled with 90% Argon gas and warm-edge spacers, our systems achieve total door $U_d$ values between 1.1 W/m²K and 0.8 W/m²K, easily complying with German GEG standards.
