Structural Engineering Application
Tailored Glazing Deployments for the Hellenic Built Environment
Operating an architectural portal between indoor and outdoor Mediterranean living requires meeting distinct structural parameters: severe wind buffeting from Aegean cyclonic patterns, intense UV-index levels, and dynamic Greek seismic safety standards.
Aegean Island Luxury Villas
Projects across Mykonos, Santorini, and Rhodes experience extreme Meltemi wind currents reaching Force 8–9 on the Beaufort scale. Our bi-fold systems utilize reinforced structural mullions, 6063-T6 multi-chamber extrusions, and heavy-duty bottom-running stainless steel tracks that prevent panel derailment under high atmospheric pressure variations.
Attica Urban Renovations
Modernization initiatives across Athens and Piraeus under the Greek National Energy Efficiency Framework (Exoikonomo Program) require rapid replacement of uninsulated legacy portals. Our slim-profile folding glass partitions deliver maximum daylight penetrance while achieving the stringent U-value thresholds mandated for Energy Class A+ compliance.
Coastal Resort Frontages
Chalkidiki and Ionian luxury hospitality layouts rely on oversized folding glass partitions to remove spatial boundaries between interior lounges and exterior pool decks. Our assemblies incorporate flushed zero-threshold drain tracks with concealed EPDM gutters, providing unimpeded accessibility fully compliant with EU barrier-free transit norms.
Market Intelligence & Codes
Emerging Architectural Drivers across Greece
The Greek fenestration and door procurement sector is experiencing a rapid technological transition driven by revised building codes and shifting climatic demands.
Strict KENAK Thermal Rules
The Hellenic Regulation on the Energy Performance of Buildings (KENAK) categorizes Greece into four climate zones (A to D). Demands for Zone C and D (Macedonia, Epirus) require complete fenestration assemblies with Uw ≤ 1.3 W/(m²·K). We incorporate engineered 34mm polyamide insulation strips to isolate heat conductance.
Qualicoat Seaside Class Finishes
Saline-saturated ocean spray combined with prolonged solar irradiance triggers filiform corrosion and chalking on standard powder coats. DERCHI manufactures folding doors treated exclusively with Qualicoat Class 2 / Seaside pre-anodized coatings, offering 25+ years of surface integrity against coastal discoloration.
Earthquake-Safe Structural Joinery
Located along the Hellenic Arc, Greek engineering codes demand exceptional dynamic structural flexibility. Our aluminum bi-fold panels utilize corner cleat crimping infused with dual-component structural polyurethane resin, allowing microscopic deflection under seismic shear stress without compromising glazing security.
| Performance Characteristic | EN Testing Protocol | Certified Performance Value | Relevance to Greek Regional Specs |
|---|---|---|---|
| Thermal Transmittance (Uw) | EN ISO 10077-1/-2 | 0.95 – 1.30 W/(m²·K) | Surpasses Greek KENAK Zone A–D standards |
| Air Permeability | EN 12207 | Class 4 (600 Pa) | Eliminates whistling drafts during seasonal windstorms |
| Water Tightness | EN 12208 | Class E900 (900 Pa) | Resists torrential rain infiltration on exposed coasts |
| Wind Load Resistance | EN 12210 | Class C5 / B5 (2000 Pa) | Survives Aegean offshore pressure fluctuations |
| Acoustic Insulation (Rw) | EN ISO 717-1 | Up to 44 dB (with laminated Low-E) | Critical for busy Athens center or resort nightlife hubs |

Frequently Asked Questions by Greek Buyers
Key legal, logistical, and technical insights for specifiers importing high-end fenestration systems into Greece.
Q:
Are your folding glass doors compliant with the Greek KENAK energy code?
Yes. Our multi-chamber thermal break profiles incorporate 34mm techno-polymer insulation barriers combined with argon-filled, warm-edge Low-E double or triple glazing. We achieve certified whole-assembly Uw ratings as low as 1.1 W/(m²·K), comfortably surpassing KENAK Zone A–D thresholds.
Q:
What surface finish protects against Aegean marine salt air corrosion?
For projects located within 5 kilometers of the Greek coastline, we supply Qualicoat Seaside-grade architectural powder coatings or 25-micron hard-anodized surface finishes. This process prevents filiform corrosion and resists chalking under intense Mediterranean UV exposure.
Q:
How do you manage freight logistics and customs clearance into Piraeus or Thessaloniki?
We provide full CIF or FOB shipping directly to Greek major ports (Piraeus, Thessaloniki, Heraklion). Shipments are accompanied by compliant Bills of Lading, Commercial Invoices, Packing Lists, Certificates of Origin, and complete CE Declaration of Performance (DoP) dossiers for rapid customs clearance.
Q:
Can you supply custom profile dimensions to fit non-standard Greek stone openings?
Yes. Custom fabrication is our core discipline. We can manufacture systems according to millimeter-precise rough openings, accommodate out-of-plumb traditional stone masonry, and provide sub-frame leveling adapters and perimeter drip profiles tailored to historic renovations.
Q:
What hardware security rating is incorporated into your bi-folding systems?
Our systems utilize European heavy-duty multi-point mushroom cam locking hardware integrated into an internal gear rod, rated up to RC2/RC3 burglary resistance standards under EN 1627. Handle mechanisms include anti-drill cylinders and internal anti-lift locks.
Q:
Can we inspect production quality and factory capacity prior to deposit payment?
We offer interactive high-resolution 360° VR factory walkthrough tours showing real-time CNC extrusion cutting, thermal crimping, and packaging processes. We also accommodate scheduled third-party video audits (TUV/SGS) and on-site visits to our 180,000 m² production facility in Foshan.
