Send an InquiryBarcelona represents one of Europe's most dynamic urban architectural landscapes. From the historic, high-density avenues of L'Eixample and Ciutat Vella to the ultra-modern waterfront developments along Diagonal Mar and Poblenou, window fenestration design requires a delicate balance between historic aesthetics, aggressive marine corrosion resistance, strict municipal acoustic dampening, and rigorous energy efficiency regulations under the Spanish Building Code (Código Técnico de la Edificación - CTE).
As a premiere OEM/ODM sliding windows supplier and exporter serving Barcelona and greater Catalonia, we specialize in high-precision, custom-fabricated aluminium fenestration systems. By bridging vertical manufacturing capabilities with direct architectural collaboration, we provide European contractors, real estate developers, and window distributors with custom profile extrusions, proprietary magnetic levitation sliding mechanisms, thermal-break structures, and specialized Low-E acoustic glass assemblies directly tailored to Mediterranean climatic challenges.
Recent updates to Spain's CTE document DB-HE (Ahorro de Energía) have elevated thermal performance mandates for building envelopes across Climate Zone C2 (which encompasses Barcelona's coastal plane). Nearly Zero-Energy Buildings (NZEB) and Passive House retrofits require exterior window openings to deliver exceptional overall heat transfer coefficients ($U_w$).
Our OEM manufacturing line integrates multi-chamber polyamide thermal break strips ($PA66 GF25$) ranging from 24mm to 34mm within extruded frames. Combined with warm-edge spacers, argon gas fill (90%+ concentration), and soft-coat Low-E double or triple glazed units (DGUs/TGUs), our custom sliding window systems achieve $U_w$ values as low as 0.8 to 1.3 W/m²K. This drastic reduction in thermal conduction mitigates summer thermal loading—drastically decreasing air conditioning energy consumption—while preventing internal condensation during humid coastal winters.
Urban acoustic pollution along major Barcelona arteries such as Avinguda Diagonal, Gran Via de les Corts Catalanes, and Passeig de Gràcia frequently exceeds 70 dBA during peak hours. Meeting the DB-HR (Protección frente al ruido) standard demands specialized acoustic fenestration solutions.
Our custom soundproof sliding and casement systems incorporate asymmetric laminated glass configurations (e.g., 6mm toughened + 1.52mm Acoustic PVB + 8mm clear) paired with continuous multi-lip EPDM compression gaskets. By eliminating air leakage channels inherent in traditional sliding tracks, our engineered units provide certified acoustic attenuation up to 45 dB (Rw, C; Ctr), restoring tranquil interior environments for high-end residential apartments, boutique hotels, and executive office spaces.
End-to-end manufacturing oversight, advanced metallurgical precision, and international logistics engineered specifically for project-based export requirements.
Eliminate traditional mechanical rollers. Our patented magnetic levitation sliding systems allow massive glazed panels (up to 600kg per sash) to glide effortlessly with fingertip force while eliminating track wear.
Our in-house facade engineering office generates comprehensive shop drawings, structural wind load analysis, cross-sectional details, and drainage schematics prior to profile cutting.
Specially formulated surface treatments tailored for Mediterranean coastal air. Certified against salt-spray pitting, blistering, and UV-induced chalking under European Qualicoat and Qualanod norms.
Tailor sightlines from ultra-minimalist 20mm interlock profiles to heavy-duty hurricane-rated frames, incorporating integrated flyscreens, motorized actuators, or hidden blind systems.
Export-ready packaging utilizing reinforced steel-stillages, corner protection guards, vacuum-sealed glass packing, and fully itemized hardware schedules for seamless customs clearance at Port of Barcelona.
Every fabricated sash undergoes pre-dispatch dry assembly, corner-weld strength testing, water tightness verification (EN 12208), and mechanical operation cycling in our ISO 9001 facility.
Providing specialized OEM solutions tuned to the specific environmental microclimates and structural typologies of Barcelona real estate.
Historic Catalan facades require strict aesthetic compliance. Our custom ODM arched windows and minimal sightline sliding systems preserve classical building geometries while integrating modern triple-pane acoustic glazing to neutralize city traffic noise.
High exposure to sea salt breeze and intense summer solar heat requires marine-grade anodized aluminum alloys, high SHGC solar control coatings, and motorized maglev sliding doors that seamlessly connect indoor living rooms to ocean decks.
Multi-story coastal towers face elevated wind loads (up to Class C5 structural resistance). We supply heavy-duty thermal break sliding systems engineered with continuous internal structural mullions and tested air permeability seals (Class 4 under EN 12207).
Providing high-frequency usage sliding balcony doors with integrated electronic smart glass (switchable privacy glass) and flush floor tracks, ensuring barrier-free accessibility and zero maintenance for hotel operators.
The table below highlights standard engineering benchmarks across our OEM/ODM aluminum sliding window product lines exported to European market partners:
| Performance Standard | Test Standard / Certification | OEM/ODM Specification Baseline | Architectural Impact |
|---|---|---|---|
| Thermal Transmittance ($U_w$) | EN ISO 10077-2 / CTE HE1 | 0.8 – 1.4 W/m²K (Thermally Broken) | Drastically reduces HVAC energy load in Mediterranean climates. |
| Acoustic Insulation ($R_w$) | EN ISO 140-3 / DB-HR | 35 dB – 45 dB (Acoustic Laminated DGU) | Blocks urban traffic, nightlife, and sea wind rumble. |
| Air Permeability | EN 12207 | Class 4 (Highest European Standard) | Eliminates micro-drafts, dust infiltration, and whistling. |
| Water Tightness | EN 12208 | Class E900 (900 Pa pressure test) | Prevents moisture driving rain ingress during heavy storms. |
| Wind Load Resistance | EN 12210 | Class C5 / B5 (3000 Pa test pressure) | Ensures zero structural deflection on high-rise coastal facades. |
| Aluminium Alloy Grade | EN AW-6063-T5 / T6 | High-purity virgin extrusions | Superior tensile strength, structural rigidity, and finishing. |
| Anodizing & Coating | Qualicoat / Qualanod | 60–80 µm Powder / 15–25 µm Anodized | Maximum resistance to saline salt corrosion and UV yellowing. |
Modern architectural philosophy across Barcelona is shifting heavily toward biophilic design and uninterrupted natural light. Architects increasingly demand zero-threshold floor transitions, ultra-slim interlocking sightlines (as narrow as 20mm), and concealed outer frames that sit flush with interior plasterwork.
Achieving this aesthetic without sacrificing thermal insulation or structural deflection requires specialized engineering. Our ODM custom minimal sliding window systems embed the thermal profile frame within the building wall cavity, while load-bearing stainless steel or magnetic tracks bear the full weight of multi-meter glass panels. This design delivers a glass ratio exceeding 95%, transforming living spaces into open-air terraces framing the Mediterranean sea.
