• 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.
