Strategic Fenestration Procurement for Turkey's Demanding Climate Zones
Navigating structural deflection, thermal resistance under TS 825, seismic code compatibility (TBDY 2018), and marine corrosion resistance for developers and architects across Istanbul, Bodrum, Izmir, and Ankara.
Thermal Compliance (TS 825)
Turkey is segmented into 5 distinct thermal insulation climate regions under Turkish Standard TS 825. From Region 1 (Antalya, Izmir) requiring solar heat gain coefficient control, to Region 4 and 5 (Erzurum, Ankara interior) demanding low U-values, our polyamide thermal barrier (PA66 GF25) bifold profiles deliver a consolidated system thermal transmittance down to Uw ≤ 1.3 W/m²·K.
Coastal Corrosion & Qualicoat Class 2
Bodrum, Marmaris, and Çeşme present extreme UV exposure coupled with high atmospheric sea salt salinity. We utilize architectural alloy 6063-T6 virgin aluminum protected by marine-grade Qualicoat Class 2 fluorocarbon/powder finishes (min. 60-80 microns) and 20-25 micron anodized surface options that undergo 3,000 hours of acetic acid salt spray testing without pitting.
Seismic Integrity & Wind Pressure
Under Turkey's comprehensive seismic regulation TBDY 2018 and TS EN 12210 wind resistance criteria, wide-span patio openings must endure racking forces without panel derailment. Our top-hung stainless steel multi-wheel carriage assemblies and interlocking reinforced mullions withstand wind gusts exceeding Class C4 / 2400 Pa.

Engineered Application Scenarios for the Republic of Turkey
Architectural fenestration needs differ dramatically between the Mediterranean, the Marmara Basin, and Central Anatolia. Our customizable aluminium folding systems are engineered around regional lifestyles and building typologies.
1. Luxury Seaside Villas in Bodrum, Çeşme & Fethiye
Mediterranean open-plan living demands full spatial synthesis between infinity pool terraces, stone patios, and central living saloons. Our bifold doors feature completely flush, thermal-break sub-floor tracks that eliminate tripping hazards while providing 95% unobstructed open spans. Coated with ultra-durable Qualicoat Class 2 finishes, the frames resist intense Aegean ultraviolet degradation and sea spray salt pitting.
- Seamless integration with motorized solar shading and retractable pleated fly screens.
- Concealed top-roller bearings protected by dual nylon-brush seals against wind-borne beach sand.
- Reinforced heavy corner corner-turning bifold options with no fixed corner posts.
2. High-Elevation Penthouses & Yalı Mansions in Istanbul
Along the Bosphorus strait (Sarıyer, Bebek, Beykoz) and in high-rise towers across Levent and Ataşehir, wind velocity and sudden localized pressure drops demand extreme structural deflection stability. Derchi's patented polyamide thermal break chambers and EPDM co-extruded triple-gasket vulcanized corner seals ensure zero draughts, absolute watertightness during severe Marmara lodos storms, and superior acoustic isolation.
- Up to 3,200 mm sash heights accommodating oversized floor-to-ceiling panoramic glass vistas.
- Acoustic laminated Low-E glazing isolating maritime foghorns and urban transit noise.
- Multi-point perimeter locking hardware meeting European RC2 / RC3 burglar resistance standards.
3. Commercial Hospitality, Cafes & Restaurants (Kış Bahçesi)
Commercial venues in Antalya's Lara beach, Izmir's Kordon promenade, and Ankara's Çankaya diplomatic quarter capitalize on outdoor seating year-round. Derchi bifold systems function as high-efficiency "Winter Garden" (Kış Bahçesi) facades, allowing hospitality operators to convert open dining verandas into temperature-controlled enclosed banquet spaces in seconds during inclement weather.
- Heavy-duty commercial hinges and floor pins tested to 100,000+ continuous operations.
- Traffic door integration allowing convenient single-panel ingress/egress without opening the full folding wall.
- Narrow profile sightlines (as slim as 115 mm interlock) maximizing customer visibility and natural light.
4. Continental Residences in Ankara, Eskişehir & Cappadocia
In Central Anatolia, where winter temperatures regularly plunge below -15°C and summer temperatures soar above 38°C, thermal insulation is paramount. Utilizing argon-filled triple-glazed units with double Low-E soft coatings and 34 mm engineered polyamide thermal breaks, our folding systems prevent interior frame condensation and drastically cut winter gas heating and summer air-conditioning expenditure.
- Compliance with strict TS 825 Zone 4 residential building thermal envelope criteria.
- Warm-edge composite glass spacer technology mitigating peripheral cold bridging.
- Anodized and powder-coated finishes immune to thermal shock and freeze-thaw degradation.
Key Drivers Reshaping the Turkish Fenestration Landscape
How evolving building regulations, the transition from PVC to architectural aluminium, and the boom in branded luxury residences are transforming fenestration specifications across Turkey.
The Transition from PVC to Slim Aluminium
Historically dominated by PVC joinery, Turkey's premium residential and commercial sectors are aggressively pivoting toward thermally broken aluminium. Large aperture spans exceeding 2.6 meters cannot be reliably supported by PVC without severe profile sagging and expansion distortion under intense Aegean and Mediterranean sunlight. Aluminium offers superior modulus of elasticity, precise geometric tolerances, and razor-sharp architectural aesthetics.
Energy Identity Certificate (EKB) Pressures
Turkey's mandated Enerji Kimlik Belgesi (Energy Identity Certificate) requires all new and renovated residential developments to maintain at least Class C or higher energy ratings. Exterior fenestration constitutes up to 35% of a building's thermal envelope loss. Contractors and architects are replacing obsolete sliding frames with certified thermally isolated bifold systems to attain prestigious green building ratings.
Growth in Coastal Branded Residences
From international resort developers in Bodrum Peninsula to marina lifestyle compounds in Izmir Urla and Göcek, high-net-worth global buyers demand luxury finishes. Large movable glass walls that stack completely out of sight have transitioned from an architectural luxury to a mandatory marketing requirement for high-end properties targeting European, Middle Eastern, and domestic investors.
