Double Hung Windows

RANGE

Double Hung windows are simple and functional in design. Ventilation is easy to regulate as top and bottom sashes can be opened as much or as little as needed for excellent air circulation, allowing warm air out the top and cool air in below. Jason’s double hung windows are counterbalanced with high quality spiral spring balancers ensuring smooth and effortless operation.
A wide variety of configurations are available offering flexibility in your designs:

  • Single or Double options
  • Single or Double with Multiple Fixed Lites
  • Single or Double with Multiple Low Lites
  • Single or Double with Multiple Hilites
PLASTER STOP

Jason’s unique Plaster Stop between the window frame and the wall plaster minimises cracking and reduces the cost of maintenance.

GLAZING OPTIONS
STRENGTH & FACE FIT FRAME MOULDING

Sturdy frame design maintains a minimum frame width of 76mm. Designed specifically for cavity brick construction and aligns perfectly with all other Jason products.
Various sized external clip-on moulds provide a perfect window to cladding alignment for frame/clad construction and has been specifically designed to complement such claddings as Cedar, Blueboard, Hardie Plank, Customorb and similar finishes.

Sash top and bottom stops are fitted to all Double Hung Windows to prevent damage when operating.

COLONIAL BAR

Jason Windows can provide a 20mm wide chamfered profile Colonial Bar that is precisely cut or bent to form a pattern of your choice on the windows to enhance the appearance and style of your designs.

COUPLERS

A full suite of extruded couplers provides neat and appealing window to window or window to door alignment. Our 180 degree straight coupler, 135 degree bay coupler and 90 degree corner coupler all accept a 65mm (outside diameter) steel column

HARDWARE OPTIONS
  • A keyed cam-catch lock is a standard feature on all Double Hung windows. Locking systems are keyed alike ensuring one key fits all.
