Tailored Fenestration for Iberian Typologies
From contemporary loft renovations in Barcelona's Eixample district to ultra-luxury villas in Marbella and multi-family residential complexes in Madrid, interior doors must balance acoustic isolation, daylight penetration, and Mediterranean lifestyle integration.
Historical Renovations (Madrid & Barcelona)
Retrofitting century-old modernist apartments requires delicate partitioning. Our ultra-slim aluminium glass sliding doors divide expansive living rooms from modern galleys or private study alcoves without stripping original plaster moldings or choking incoming balcony daylight.
Luxury Coastal Villas (Marbella, Ibiza, Mallorca)
High-end Mediterranean villas demand flawless transitions between open-concept living quarters, interior courtyards (patios), and master en-suite bathrooms. Our fluted tempered glass systems offer visual privacy while marine-grade Qualicoat finishes endure coastal humidity.
Hotel Boutique & Modern Workspaces
Boutique hotels and tech hubs across Valencia and Bilbao require heavy-duty performance under continuous duty cycles. We provide reinforced aluminium profiles with acoustic seals reaching Rw 35–40 dB, creating peaceful suites and quiet boardroom environments.
Iberian Market Whitepaper: Technical Trends in Interior Glazing
The Spanish interior door sector is experiencing a permanent shift away from heavy, solid timber millwork toward high-precision aluminium and architectural glass systems. Key macro market drivers include:
- Open-Concept Spatial Management (Concepto Abierto): Homeowners in urban centres demand visual continuity. Glass partitions maintain sightlines while preventing kitchen odors and conditioning loss between climate zones.
- Stricter CTE Compliance (Código Técnico de la Edificación): Document DB-HR requires stringent acoustic separation between sleeping and daytime living quarters. Standard hollow interior doors fall short; dual-glazed aluminium systems offer verifiable lab-tested acoustic suppression.
- Qualicoat & Seaside Durability: In coastal autonomous communities such as Andalucía, Cataluña, and the Balearic Islands, traditional steel frames oxidize and timber swells. Precision-extruded 6063-T5 aluminium with 15-20 micron anodized or powder-coated surfaces provides lifecycle resilience with zero maintenance.
Common Questions by Spanish Architects, Promotores & Importers
Clear answers on technical specifications, Spanish building code documentation, sea freight logistics to Valencia or Barcelona, and container consolidation options.
CTE Do your aluminium glass doors comply with the Spanish CTE DB-SUA?
Yes. Under DB-SUA (Seguridad de Utilización y Accesibilidad), all interior glass panels subjected to impact risks must utilize safety glazing. We fit toughened safety glass compliant with UNE-EN 12150-1 or laminated safety glass compliant with UNE-EN ISO 12543, fully documented for municipal building inspection (licencia de primera ocupación).
Acoustic What acoustic attenuation (DB-HR) can your internal partitions achieve?
For residential and boutique hotel suites, our double-glazed interior French and casement doors achieve certified sound transmission losses of Rw 34 dB to 40 dB when configured with acoustic PVB interlayers and perimeter magnetic or EPDM drop-down acoustic threshold seals.
Logistics What are the lead times and shipping terms to Spanish commercial ports?
Standard production cycles are 25 to 35 calendar days following final CAD shop-drawing signoff. Ocean transit from Foshan / Shenzhen to Puerto de Valencia, Barcelona, or Algeciras is typically 28 to 35 days. We quote transparent FOB China, CIF, or DDP terms through experienced forwarding partners.
Custom Can you engineer bespoke dimensions for non-standard Spanish structural openings?
Absolutely. As a true factory direct manufacturer, we do not restrict buyers to standard metric modular sizes. We engineer custom openings up to 3.5 meters high with pivot floor springs, flush pocket sliders, or multi-panel telescopic configurations supported by free CAD/BIM shop drawings.
Packing How do you prevent glass transit damage during intercontinental sea freight?
Every glass door panel is packaged with protective peelable surface films, high-density edge corner guards, corrugated wrap, and crated inside fully sealed, fumigated non-coniferous plywood crates with built-in internal shock buffers and desiccants for moisture control.
Consolidation Can we consolidate entry doors, interior doors, and garage doors in one container?
Yes. Leveraging our 180,000㎡ industrial complex, Spanish developers and wholesalers frequently consolidate high-security exterior entrance doors, interior minimalist glass doors, and motorized garage doors into a single 40ft HQ container, slashing landed shipping overhead by up to 40%.
