A gas strut window for every alfresco.

  • 1810mm

Stylish and Secure

Double cylinder locks are supplied as standard. Gas strut windows are lockable from inside and outside.

Built to Last

The sturdy design maintains a minimum frame width of 100mm, while its versatility makes it suitable for both cavity brick and timber-framed construction. Mohair brush seals fitted to the sill reduce air leakage, ensuring the home gets maximum efficiency from heating and cooling.

Sill-less Option

The sill-less option provides a seamless transition from inside to out, enabling the benchtop to be installed in one piece.

Note: The sill-less option is not weatherproof and therefore not warrantied for water ingress. Jason Windows recommends the sill-less option be installed under the main roof in a covered location, i.e. alfresco areas.

Jason Gas Strut Window without a sill creates great open space on the shared kitchen & alfresco bench.

Glazing Options

The role glass plays in the ongoing performance and comfort of a home is often overlooked when building or renovating. Glass has a significant impact on the comfort levels, natural light and security of your home. Your home’s orientation and your family’s needs should also be considered when selecting the right glass solution for you.

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

BAL Ratings

The BAL assesses a home’s risk level of a potential ember attack, radiant heat, and direct flame contact.

The BAL (Bushfire Attack Level) is a rating system that states the construction requirements under the Australian Standard AS3959-2009 to improve the protection of your home from a potential bushfire attack. Your builder will advise if your home is subject to a BAL rating. A Jason Windows product specialist can then assist you with your BAL rating and your window, door and screen requirements to ensure your home meets the code.
