Understanding acoustic wave damping, sound transmission loss (STL), and thermal performance under Spain’s Technical Building Code (CTE DB-HR & CTE HE).
Equal double glazing panes suffer from sympathetic resonance at specific frequencies. Our systems utilize asymmetrical glass configurations (e.g., 6mm Low-E + 16Ar + 8.76mm Soundproof Laminated) to disrupt coincidental frequency dips, delivering up to +8 dB acoustic gain over standard double glazing.
By incorporating specialized Viscoelastic Acoustic Polyvinyl Butyral (Acoustic PVB) interlayers within laminated glass panels, our windows transform sound vibration energy into negligible heat energy, effectively dampening low-frequency urban traffic rumble (100Hz–315Hz) common in Spanish metropolitan zones.
Combining acoustic dampening with energy efficiency, structural multi-chamber Polyamide (PA66GF25) thermal break strips physically isolate the interior aluminum profile from exterior climate extremes, preventing condensation in humid coastal areas and minimizing summer cooling loads in Andalusia and Madrid.
Factory certified performance values according to UNE-EN ISO 10140-2 and UNE-EN ISO 717-1 standard testing protocols.

Customized glass and frame engineering tailored to Spain’s diverse regional building demands, urban density, and microclimates.
High-density Spanish city centers suffer from high ambient nightlife and traffic noise levels (exceeding 70 dBA). Our high-mass asymmetrical double glazing combined with continuous triple EPDM compression gaskets attenuates sound by up to 45 dB, allowing urban apartment hotels and residential conversions to comfortably comply with local sound insulation regulations (CTE DB-HR).
Coastal environments in Marbella, Ibiza, and Mallorca demand extreme resistance against salt spray corrosion coupled with low Solar Heat Gain Coefficients (SHGC). We treat our 6063-T6 aluminum frames with 25-micron anodization or Qualicoat Marine-Grade powder coating, paired with double-silver Low-E coating glass units to block up to 72% of solar infrared radiation.
Northern Spanish territories experience heavy rainfall, strong wind loads, and severe winter cold. The NT91 Passive House Certified Triple Glazed Window features ultra-wide thermal breaks and multipoint perimeter locking pins, delivering high water resistance (Class E1050) and suppressing high-frequency wind howling noise during winter storms.
Strategic insights for Spanish architectural firms, project developers, and window importers.
Spain’s Código Técnico de la Edificación (CTE DB-HR) mandates strict airborne noise isolation ($R'_w$) of at least 30 dBA to 45 dBA for residential facades depending on noise zone exposure. Foreign suppliers must provide verified sound transmission loss test reports from accredited laboratories to satisfy municipal building inspectors.
With Spain enforcing the energy efficiency standard CTE HE (Ahorro de Energía), luxury residential developments in Valencia, Alicante, and Madrid require window frame U-values ($U_w$) under 1.4 W/m²K. Integrating thermal break polyamide barriers with high-efficiency double low-E glazing units is now the standard baseline requirement for modern Spanish real estate projects.
Contemporary Spanish architectural design heavily favors ultra-slim profile sightlines that maximize natural daylight. However, meeting high wind-load ratings (Class C5 under UNE-EN 12210) requires high-strength 6063-T6 aluminum alloy extrusion profiles engineered with internal structural web reinforcing ribs.
As a specialized manufacturer of high-performance architectural aluminum window and door systems with over 25 years of engineering experience, our state-of-the-art facility provides complete end-to-end production integrity: from precision CNC aluminum extrusion machining to automated insulated glass assembly.
Automated 5-axis CNC machining centers ensure corner miter joint tolerances under 0.1mm, creating flawless air-tight compression seams.
Standardized compatibility with premium European hardware systems (Siegenia, Giesse, Roto, Savio) for effortless long-term operation.
Reinforced steel-banded wooden crate packaging optimized for sea freight shipment directly to Barcelona, Valencia, and Bilbao ports.
Clear technical and commercial answers regarding procurement, regulatory compliance, freight, and customization.
Yes. Our double and triple glazed acoustic window systems are engineered to achieve weighted sound reduction index values ($R_w$) ranging from 38 dB up to 48 dB. When configured with asymmetrical laminated glass and acoustic PVB, they fully comply with and exceed the mandatory facade sound insulation requirements under Spain’s Technical Building Code (CTE DB-HR).
For Spanish coastal environments, we recommend a double-glazed build-up consisting of 6mm solar control Low-E glass + a 16mm Argon gas filled cavity with a warm-edge spacer + 8.76mm acoustic laminated glass. This combination offers high thermal insulation ($U_w \le 1.2 \text{ W/m}^2\text{K}$), low solar heat gain (SHGC < 0.35), and maximum resistance against marine air corrosion.
We routinely supply project orders across Europe. Windows are packaged in heavy-duty, moisture-proof plywood crates with protective corner guards and A-frame glass supports. We offer complete FOB, CIF, or DDP shipping options to major Spanish ports including Valencia, Barcelona, Bilbao, and Algeciras, providing all required export documentation and CE declarations.
Absolutely. We specialize in custom architectural fabrication. Using precision CNC profile bending technology, we produce customized arched casement windows, colonial grid layouts, and oversized sliding systems tailored directly to your architect's CAD or BIM elevation drawings.
We provide Qualicoat-certified architectural powder coatings (over 200 RAL colors), wood-grain heat transfer finishes, and 15–25 micron anodization options. For seaside installations in Spain, our standard practice includes a pre-anodization fluorocarbon anti-corrosion pre-treatment to ensure a 20+ year surface durability guarantee against saltwater exposure.
Standard production time is between 25 to 35 days following shop drawing sign-off and material specification approval. Ocean transit from our factory port to major Spanish ocean terminals typically takes an additional 28 to 35 days depending on the shipping line route chosen.
