OEM/ODM Aluminium Tilt And Turn Windows Factory & Suppliers

Tilt and Turn windows offer distinct operational advantages over standard exterior-swing casements. First, they tilt inward at the top for safe, continuous ventilation without allowing rain to enter or creating draughts. Second, they swing fully inward like a door, allowing safe interior cleaning of exterior glass surfaces—an essential feature for multi-story residential and commercial buildings where exterior window washing is difficult or costly. Third, they utilize perimeter multi-point locking hardware that clamps the sash firmly against triple EPDM weather-stripping, achieving superior air tightness, water resistance, and acoustic insulation compared to typical push-out casements.

Yes, absolutely. We operate as a full-service OEM/ODM manufacturer. Every order is custom engineered based on your project requirements, structural opening dimensions, wind-load requirements, and elevation drawings. Our technical engineering team provides detailed 2D shop drawings and 3D BIM models for sign-off prior to extrusion and assembly. You can specify exact profile wall thicknesses, thermal break sizes, powder coating colors (RAL/NCS color systems), glass build-ups, and hardware suppliers (e.g., German Roto, Siegenia, or premium domestic hardware).

We offer custom insulated glass units (IGU) manufactured in-house. Options include double-pane insulated glass (e.g., 5mm+12A+5mm or 6mm+16A+6mm), triple-pane energy-saving units (e.g., 5mm+12A+5mm+12A+5mm), soft-coat Low-E coated glass, argon gas filling (up to 90%+ purity concentration), warm-edge composite spacers, and acoustic laminated glass (e.g., 6mm + 1.14/1.52 PVB/SGP + 6mm). Depending on your selection, acoustic performance can reach STC 45+ dB and thermal insulating U-factors can be tuned below 1.0 W/m²K.

Quality control at Doorreme follows strict ISO9001 quality management protocols across five production stages: 1) Spectrometric inspection of incoming raw 6063 aluminum billets; 2) Profile dimensional tolerance and coating film thickness checks (anodizing/powder coating adhesion tests); 3) CNC machining precision monitoring; 4) 100% pre-assembly inspection of sash squareness, hardware operation, and corner seam alignment; 5) Dynamic water tightness, air infiltration, and structural wind pressure sampling in our factory testing chamber.

Our window and curtain wall systems are tested and certified to comply with major international standards. For Australia and New Zealand, we comply with AS2047, AS1288, AS2208, and AS4666. For North America, our products carry NFRC thermal performance ratings and CSA compliance for structural and weather performance. For Europe and international markets, our products meet CE marking requirements under EN 14351-1. Complete test reports are provided during project approval.

Because we operate a 123,000 m² automated facility, our production capacity reaches over 500,000 square meters per year. For standard custom project orders, lead times are generally 25 to 35 calendar days following final shop drawing confirmation and deposit receipt. We support custom engineering for commercial developments without rigid minimum quantity limits, though full container loads (20GP/40HQ) offer the most economical freight cost per unit.

We use multi-layer protective packaging engineered for international ocean freight. First, glass and powder-coated frame surfaces are wrapped with protective non-scratch PE film and corner guards. Second, units are wrapped in thick bubble wrap or EPE foam. Third, products are loaded into reinforced fully-enclosed fumigated plywood crates or customized steel stillages designed for easy forklift unloading at project sites. This ensures zero glass breakage or surface scratching upon arrival.
