Double Hung Windows

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 Double Hung Windows are counterbalanced with spiral spring balancers ensuring smooth and effortless operation. A variety of configurations are available:

  • Single or Double
  • Single or Double with Multiple Fixed Lites
  • Single or Double with Multiple Low Lites

Glazing Options

Anneled glass is supplied as standard. Other upgrade options include:

  • Toughened (Safety Glass)
  • Laminated (Safety Glass)
  • Toned (Tinted Glass)
  • Low E

To improve energy efficiency further, consider Low E energy efficient glass to reduce the transfer of heat or cold through the glass. Your home will stay warmer in the winter and cooler in the summer. Low E glass is like insulation panels for your home.
