Precision-engineered thermal break glass systems, minimalist sliding doors, and structural facades manufactured to strict European standards (EN 12020-2 / DIN EN 12150).
The evolution of contemporary architecture in Berlin is fundamentally defined by the seamless transition between indoor spaces and surrounding urban microclimates. Modern structural frameless glass—characterized by ultra-slim sightlines, structural interlayers, and high thermal insulation—has shifted from a purely luxury aesthetic to a core requirement for commercial and residential developments across Germany.
Structural glass in Germany is strictly governed by DIN 18008-1 through DIN 18008-6. Unlike conventional framed windows where the perimeter aluminum frame bears primary structural forces, frameless glass walls and minimal-frame sliding systems transfer dead loads, wind pressure, and barrier loads directly through laminated glass panels. Our engineering manufacturing facility integrates SGP (SentryGlas® Plus) ionoplast interlayers and toughened safety glass (ESG-H heat-soaked) to ensure structural integrity up to 2.4 kPa wind suction forces typical of Berlin tall building facades.
Berlin experiences harsh winter temperature drops down to -15°C, demanding strict control over energy loss. Standard double glazing is no longer sufficient for major renovation or new build projects in Berlin Mitte or Charlottenburg. Our triple-glazed frameless systems utilize double-pass soft-coat silver Low-E layers, 90% Argon gas filling, and warm-edge TGI/Swisspacer bars. This configuration routinely achieves $U_g$ values down to 0.5 - 0.7 W/m²K and combined system $U_w$ values under 0.85 W/m²K, surpassing Passive House standards.
Urban density in Berlin—such as developments adjacent to major arterial roads (e.g., Friedrichstraße, Kurfürstendamm) or S-Bahn rail corridors—presents severe sound acoustic challenges. According to DIN 4109 (Sound Insulation in Buildings), standard glass fails to isolate low-frequency urban noise. Our custom frameless glass assemblies incorporate asymmetric glass thickness builds (e.g., 8mm outer / 16mm cavity / 6mm inner) combined with acoustic PVB interlayers (Vanceva Sound), delivering certified acoustic decoupling up to $R_w = 45\text{ dB}$.

Every Berlin district imposes unique urban planning constraints (Bebauungsplan), historical preservation guidelines (Denkmalschutz), and environmental requirements. Direct factory custom engineering enables precise architectural adaptation.
Converting 19th-century industrial buildings and historic apartments into high-end residential lofts requires minimal visible frames to maximize natural light without altering structural brick masonry. Our custom minimal polymer and aluminum hidden frame sliding glass systems fit directly into existing structural openings, blending seamlessly with historic architectural facades while exceeding GEG 2024 thermal insulation mandates.
High-end single-family residential projects in Berlin's western suburbs emphasize floor-to-ceiling glass walls, expansive multi-track sliding doors, and corner glass-to-glass connections without vertical posts. We engineer custom motorized lift-and-slide doors capable of driving glass panels weighing up to 400 kg per sash with smooth, whisper-quiet operation.
Commercial high-rises and flagship stores in Berlin demand structurally integrated glass curtains with structural silicone bonding (Structural Glazing - SG). Our factory produces pre-assembled unitized curtain wall cassettes with thermal break frames and dual-sealed insulated glass units, accelerating on-site installation schedules in congested downtown traffic zones.
By eliminating intermediary trading entities, we offer direct factory engineering, rigorous European testing compliance, and seamless containerized delivery to job sites in Berlin and Brandenburg.
All supplied glass and profile systems are manufactured under stringent Qualicoat / Qualanod powder coating protocols (minimum 60 µm coating thickness) and tested according to European Standards: EN 1026 (Air Permeability), EN 1027 (Watertightness), and EN 12211 (Wind Resistance). Full factory test dossiers and CE declarations are provided for German municipal building approval (Bauaufsichtliche Zulassung).
Our engineering team reviews your architectural elevations, window schedules, and CAD/DWG files. Within 72 hours, we generate comprehensive structural feasibility feedback, cross-sectional profile drawings, preliminary U-value calculations, and fixed itemized bills of quantities (BOQ) with zero hidden fees.
To eliminate shipping transit damage, oversized glass panes and glass doors are packed in heavy-duty ISPM-15 fumigated wooden crates with internal steel bracing, corner edge guards, and desiccant packs. Each crate is systematically tagged with project elevation codes to facilitate sequential offloading on Berlin construction sites.
Expert answers to standard structural, technical, freight, and regulatory queries from local developers and contractors.
Our frameless sliding doors and structural glass assemblies achieve GEG 2024 compliance by utilizing multi-chamber polyamide thermal break extrusions combined with high-performance triple glazing (Ug = 0.5 - 0.7 W/m²K). We incorporate warm-edge spacer technology (Swisspacer Ultimate / TGI) and argon gas filling, yielding a total window U-value ($U_w$) well below the mandatory German energy limit of 0.95 W/m²K for modern residential construction.
Yes. All frameless glass panels destined for barrier glazing, overhead skylights, or floor-to-ceiling facades are calculated in accordance with DIN 18008 parts 1 through 6. We utilize toughened safety glass (ESG-H heat-soaked to prevent spontaneous nickel-sulfide breakage) and laminated safety glass (VSG) featuring structural SGP (SentryGlas®) interlayers for maximum fall-through protection (Absturzsichernde Verglasung).
Standard manufacturing lead time for custom engineered frameless glass sliding systems and curtain walls is approximately 25 to 35 calendar days following final DWG sign-off. Transit time via ocean freight to Northern European ports (e.g., Hamburg or Bremerhaven) with direct rail connection to Berlin freight depots takes approximately 20 to 28 days. Expedited air or consolidated logistics solutions are available for urgent project schedules.
Every shipment is accompanied by a complete technical dossier, including: CE Certificates of Performance (DoP), factory test reports for air, water, and wind performance under EN 1026 / 1027 / 12211, glass batch quality certificates (DIN EN 12150 / DIN EN 14449), profile aluminum alloy reports (EN AW-6063-T6), and detailed shop assembly drawings for local installer sign-off.
To mitigate high dB acoustic pollution along S-Bahn and main arterial roads in Berlin, we specify asymmetric laminated acoustic glass (incorporating Vanceva or Sekisui acoustic interlayers). Hardware options include premium German-engineered concealed locking systems (such as ROTO hardware or G-U concealed multi-point gear) paired with triple-lip EPDM weather gaskets, delivering certified acoustic damping up to 45 dB.
We work on a flexible project-basis rather than strict piece minimums. The most cost-efficient procurement threshold is a consolidated container load (20ft or 40ft FCL), which can combine window units, sliding glass doors, pergolas, and hardware for a single villa or an apartment floor. Mixed LCL shipments are also accepted for smaller architectural renovations.
