Do you choose Aluminum casement windows or Sliding windows ?

Available in side-hung and tilt-turn configurations, these window systems achieve 85% free ventilation area through optimized pivot mechanics. The 15° tilt position enables continuous airflow while deflecting precipitation via integrated drip channels.

Architectural Integration

Modular framing accommodates jumbo glazing units up to 3m², maintaining ≤45mm sightlines through precision-extruded profiles. Custom grid patterns (colonial/contemporary) are achieved via mechanically fastened glazing beads without structural compromise.

Pressure-Activated Sealing

Seven-point compression locking engages EPDM perimeter gaskets under 12N·m torque, creating IP68-rated barriers. Laboratory testing confirms:

• 42dB airborne noise attenuation (ASTM E90)

• 0.8 ACH air infiltration (ASTM E283)

• U-factor 1.05 W/m²K (NFRC 100)

Security Engineering

Forged stainless steel friction stays (DIN EN 13126-5 compliant) combine with shootbolt mechanisms resisting 1500N anti-burglary loads. Multi-axis CNC-milled hardware ensures 0.2mm operational tolerances throughout 20,000-cycle durability testing.

Energy Saving Aluminum Casement Window

• Design Flexibility: Accommodates unlimited mullion configurations through modular framing, achieving 85% vision area in curtain wall applications.

• Premium Applications: Standard in Class A commercial towers with:

◦ ≤15% operable sash ratio for panoramic glazing

◦ 180° continuous ventilation capability

◦ EN 14351-1 compliant 2500Pa wind resistance

Thermal-Break Sliding Systems

• Industrial Adaptation:

◦ Fixed 50/50 horizontal split configuration

◦ 1200mm max single slide span (EN 13115)

◦ Ideal for:

■ Warehouses requiring 2.4m clear openings

■ Rural dwellings with 600-900mm track systems

◦ 35dB acoustic rating vs casement's 42dB

Thermal Break Aluminum Casement Windows

• Wind Load Resistance: Compact 45mm profile cross-sections integrate structural reinforcement channels (2.0mm wall thickness) at critical stress points - reinforced mullions and vertical transoms achieve EN 12210 Class 4 wind resistance rating (2400Pa).

• Sealing Hierarchy:

Casement: Compression-activated perimeter EPDM gaskets (Shore A 70±5) achieve 0.8 ACH air infiltration (ASTM E283)

Sliding: Brush seals with stainless steel carriers maintain 1.5 ACH, suitable for moderate climate zones

Material Specifications

• Reinforced corners feature 2.5mm galvanized steel inserts (EN 10346 DX51D)

• Glazing pockets incorporate triple-layer silicone-based sealant (ASTM C920 Type S)

• Multi-axis CNC-milled hardware ensures 0.15mm operational tolerances
