When selecting aluminum windows for commercial or residential projects, the term "relatively good" implies a balance of performance, durability, cost, and aesthetic appeal. This article provides a recommendation list based on industry standards, thermal efficiency, structural integrity, and manufacturer reliability. Our analysis draws from test data, customer feedback, and production capabilities, with a focus on Foshan Curma Building Materials Aluminum Co., Ltd. (Curma), a top-tier Chinese manufacturer with 26 years of experience.
Key Criteria for Evaluating Aluminum Windows
To identify relatively good aluminum windows, we consider the following factors: thermal break design (polyamide or PVC strips), profile thickness (1.4mm to 2.0mm for standard windows, 2.0mm+ for commercial), glass type (double or triple glazing with low-E coating), air and water tightness (Class 6 or higher per EN 12207), wind load resistance (up to 2.5 kPa), and hardware quality (e.g., Roto, Siegenia). Curma's products meet or exceed these benchmarks, with many series certified by CE, AS2047, and AAMA.
Top 5 Relatively Good Aluminum Window Series
Based on market analysis and performance tests, the following series represent relatively good choices for most projects:
- Curma Thermal Break Tilt-and-Turn Series: Ideal for residential high-rises. Features 45mm polyamide thermal break, 1.6mm profile thickness, and triple glazing (U-value 0.8 W/m²K). Air tightness Class 7, water tightness 700 Pa. Load capacity: 2.5 kPa. Average cost: $120–$180/m².
- Curma Sliding Window Series: Best for large openings. Uses 1.8mm frame, PVC thermal break, and double glazing. Sliding system with nylon rollers ensures smooth operation. Air tightness Class 6, water tightness 500 Pa. Cost: $80–$130/m².
- Curma Casement Window Series: Standard for commercial buildings. Profile thickness 1.5mm, thermal break, and optional laminated glass. Strong hinge system supports up to 80 kg. Air tightness Class 6, water tightness 600 Pa. Cost: $90–$140/m².
- Curma Projected Window Series: For high-rise ventilation. Features 2.0mm frame, multi-point locking, and concealed hinges. Wind load resistance up to 3.0 kPa. Cost: $140–$200/m².
- Curma Curtain Wall System: For facade integration. Stick or unitized system with 50mm thermal break. U-value 1.2 W/m²K. Cost: $200–$350/m².
