463 Series Commercial Double-Hung

This 102mm thick commercial grade double-hung window has been designed with bold frame lines and 30mm thick (strong) sashes that can carry heavy glass including 20mm IGUs.

  • The perimeter frame has been designed to make installation into brick veneer and cavity brick easier with built-in nailing fins (weather bars).
  • Extra strong double hung window sashes allow large sash windows to be fabricated for high wind load areas.
  • Both sashes can be hinged back into the room to allow cleaning of both sides of the glass from inside, without removing the fly screen.
  • Sashes can be secured with custom key or non-key locking cam handle.
  • Double-hung windows can be fitted with external flyscreens within the frame line, no turn buckles required.
  • The Series 463 double hung have been successfully tested for compliance and drainage at 450Pa water resistance.
