A double hung window features two vertically sliding sashes. The Tilt 24 mechanism allows both sashes to tilt inward, enabling safe and effortless cleaning of the exterior glass from inside your home.

Our UPVC double hung windows meet AAMA standards, are NFRC certified for energy performance, and achieve N6 CLASS under the AS2047 standard for structural safety and weather tightness.

We offer double toughened glazing (such as 5mm+12A+5mm Low-E or Tinted), single toughened glazing, and laminated safety glass. Double glazing with Low-E provides excellent energy efficiency and sound insulation (RW ≥ 30 dB).

We utilize top-grade hardware options including German brands (Roto, Siegenia, Geze), Australian Doric hardware, and premium Chinese brands (Kinlong, Zhenjiang) to ensure smooth operation and security.

All our AAMA standard UPVC double hung windows come with a comprehensive 10-year warranty covering profiles, finish, and structural performance.
