Precision-fabricated architectural fenestration solutions compliant with ISO, NFRC, UL, and European structural standards for high-end residential and commercial projects in Istanbul.
Istanbul occupies a unique geographic position straddling two continents, where the humid subtropical climate of the Black Sea meets the Mediterranean atmospheric patterns of the Marmara Sea. For real estate developers, structural engineers, and architectural firms operating across districts like Sarıyer, Beşiktaş, Kadıköy, and Levent, fenestration specification is not merely a aesthetic choice—it is a critical building physics parameter.
As China’s top exporter of custom aluminium composite windows, thermal break sliding assemblies, and structural glass curtain walls, Doorreme Aluminum Industry Co., Ltd. delivers engineered fenestration systems tailored to withstand Istanbul’s complex climatic challenges:
Turkey’s TS 825 thermal protection standard demands stringent heat loss coefficients. Our polyamide PA66GF25 thermal barrier strips break thermal paths, significantly reducing heating costs during cold Marmara winters and cooling loads in summer.
Bosphorus waterfront properties require surface durability against moisture and salt. We utilize 6063-T6 architectural grade aluminium treated with Qualicoat Class 2 anodizing or 30-micron PVDF coatings to eliminate corrosion risk.
Urban density along arterial routes like the D100 and E5 highways demands severe noise reduction. Our double-sealed EPDM gaskets combined with asymmetric 6mm+16A+6mm acoustic laminated glass achieve sound isolation up to 48 dB.
Doorreme integrates solid wood interior warmth with external high-gauge extruded aluminium strength. Below is a structural engineering matrix comparing our primary fenestration systems specified by Turkish contractors and architectural consultants:
| System Series | Structural Profile Thickness | Glazing Configuration | Thermal Performance (U-Factor) | Acoustic Isolation | Recommended Application |
|---|---|---|---|---|---|
| Aluminium-Clad Wood Casement | 1.4mm Profile + Solid Oak/Pine Interior | 5mm + 18Argon + 5mm Low-E Tempered | Uw ≤ 1.1 W/m²K | STC 42 dB | Luxury Villas (Zekeriyaköy, Beykoz) |
| Thermal Break Casement / Tilt & Turn | 1.4mm - 2.0mm Thermal Aluminum 6063-T6 | 6mm + 16A + 6mm Double Glazed Low-E | Uw ≤ 1.3 W/m²K | STC 45 dB | Urban Transformation Apartments (Kadıköy) |
| Ultra-Slim Lift & Slide Terrace Doors | 2.0mm Heavy-Duty Track & Frame | 6mm + 20A + 6mm Toughened Insulating Glass | Uw ≤ 1.4 W/m²K | STC 40 dB | Hotels & High-Rise Patios (Şişli, Ataşehir) |
| Structural Glass Curtain Wall (SSG) | 80mm Wall Thickness Mullion/Transom | 8mm Low-E + 12A + 8mm Laminated Security | Uw ≤ 1.2 W/m²K | STC 46 dB | Commercial Office Towers & Malls |
| UL-Listed Steel Security Fire Doors | 1.5mm - 2.0mm Galvanized Steel Core | Fire-Rated Intumescent Core / Wire Glass | Thermal Insulation / 120-min Fire Rating | STC 38 dB | Apartment Stairwells & Commercial Exits |
Every system exported to Turkey undergoes full factory assembly, structural deflection testing under 5000 Pa wind pressures, and multi-point hardware verification (utilizing German Roto, Hoppe, or top-tier OEM locking systems).
Istanbul is undergoing unprecedented urban renewal under the municipal Kentsel Dönüşüm (Urban Transformation) initiative. Older concrete structures are being replaced with earthquake-resilient, energy-efficient residential complexes. Concurrently, historical preservation districts in Sultanahmet, Galata, and Karaköy require retrofitting window profiles that maintain historic character while meeting modern efficiency targets.
Modern residential developments in Ataşehir, Ümraniye, and Beylikdüzü prioritize energy ratings to earn LEED or BREEAM certifications. Doorreme supplies low-emissivity (Low-E) double and triple-glazed units filled with 90% Argon gas, reducing energy exchange and contributing valuable carbon-footprint reduction credits for developer portfolios.
Replacing deteriorating timber windows in historical Istanbul zones requires strict compliance with exterior sightline geometry. Doorreme's aluminum-clad solid wood casement series reproduces historical profile contours on the inside while offering weather-proof aluminum cladding on the exterior, solving timber decay issues caused by damp coastal air.
As a global fenestration manufacturer based in Foshan, China's premiere aluminium industrial hub, Doorreme Aluminum Industry Co., Ltd. operates a 123,000 m² state-of-the-art facility equipped with imported German Elumatec CNC machining centers and Italian automatic glazing lines.
Over 800 skilled workers and 500,000 m² annual capacity ensure short lead times even for mega-scale mixed-use developments and hotel chains across Turkey.
Certified under ISO9001, NFRC, UL, and CE. Every frame unit undergoes strict 100% pre-shipment dry assembly, diagonal tolerance verification, and seal testing.
Complete export packing in heavy-duty plywood crates with air-cushion separation. Full export documentation support including Certificate of Origin, ATR forms, and custom clearance paperwork.
