Casement Windows Range

Jason Casement Windows are perfect for achieving aesthetically pleasing, unobstructed views while maximising natural light and ventilation.

Security

Stylish yet secure. Jason Casement Windows are designed with a latch to pull the sash into the window frame for a weather tight seal and improved security. Optional opening restrictors are available.

PERFORMANCE & RELIABILITY

Effortless operation is achieved through stainless steel supports. Year-round weather proofing is facilitated by high quality window seals.

DESIGN & AESTHETIC

Architectural symmetry allows for design integration with other Jason Window Commercial products, including fixed windows to create an appealing feature in your home.

GLAZING OPTIONS

Annealed glass is supplied as standard, other upgrade options include:

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

Learn more about these glass types here.

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.

Double Glazing
Traditional window glazing consists of a single sheet of glass. Double glazing consists of two panels of glass in a sealed unit separated by a layer of air or argon gas. The Jason Double Glazing Range uses argon gas to create a more effective insulation break. This greatly reduces both heat flow and thermal conductivity through the window. The thermal benefits of double glazing make it ideal for rooms where greater control of heat gain or loss is required.

FLYSCREENS

Casement Windows are designed to accept a standard flyscreen covering the opening from the inside. Jasons flyscreens are manufactured using a sturdy extruded aluminium section rather than with lightweight roll form material to give extra strength.

The screens can be fitted with a range of mesh options and are flush fitting with easy installation and removal.
