Thermal-Break Double-Hung Window Systems
Engineered for precision airflow control, our aluminum double-hung windows combine heritage aesthetics with modern performance. The 6063-T5 thermal-break profiles (2.0mm reinforced walls) and 125mm track system achieve U-values as low as 0.14 W/ft²·K (0.8 W/m²K) through 5mm+12Ar+5mm Low-E glazing with integrated lace bars for structural rigidity.

Specialized tilt-and-lift hardware enables effortless single/double operation, featuring 100,000-cycle tested stainless steel balances and multi-point locking. Choose from automotive-grade tempered glass options: triple laminated for 48dB noise reduction, solar-reflective coatings for desert climates, or frosted privacy panels.

The interlocking sash design creates IP54-rated seals when closed, blocking dust infiltration and insect entry. Powder-coated finishes in 18 RAL colors withstand 1,500-hour salt spray tests, while PVDF woodgrain options mimic traditional timber without maintenance.

Certified to ASTM E283 air infiltration standards, these windows accommodate structural shifts up to ±8mm – ideal for historic renovations or hurricane-prone coastal residences. Optional smart sensors automate ventilation based on humidity, blending colonial charm with IECC-compliant efficiency.
