Air and flair. Discover the charm of a double hung window.

Jason aluminium double hung windows are simple and functional in design. Enjoy total control over the air circulation in your room by opening either the top or bottom sashes as much or as little as needed, allowing warm air out the top and cool air in below for perfect ventilation. Jason Double Hung Windows are counterbalanced with spiral spring balancers to ensure 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

Features

Built To Last

Our sturdy double hung window frames offer a minimum width of 76mm for maximum sturdiness and strength. Suitable for both double brick and framed construction. Top and bottom stops are fitted to all Jason Double Hung Windows to prevent damage when operating.

Berms and Barrells in Margaret River have used Jason Double Hung windows on their trendy holiday accommodation. Pictured here is the outdoor shower for rinsing off after a surf, situated between two double-hung-windows.

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 be considered when selecting the right glass solution for you.

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

Toughened (Safety Glass)

  • Suits areas where windows require structural strength and safety, such as large feature windows and raked ceiling windows
  • Suits areas most prone to injury from human impact such as bathrooms, kitchen splashbacks, doors and full-length windows
Modern kitchen with hues of grey and white, with a glass window splashback using toughened glass.

Screens

Aluminium Mesh

  • Suitable for bushfire rated zones, complies with AS3959 up to BAL29
aluminium mesh

Steel Mesh

  • Stronger than aluminium mesh
  • Good corrosion resistance
  • Suitable for bushfire rated zones, compiles with AS3959 up to BAL29
steel mesh

Migi Mesh

  • Superfine to keep out tiny insects
  • Recommended for homes near waterways

Security Screens

Flyscreens are perfect for keeping insects such as flies, wasps, sandflies, mosquitoes, midges and spiders on the outside – but flyscreens alone are not designed to keep children and pets contained inside.
If security for children and pets is a concern, we recommend you upgrade to Jason Security Screens. Security screens provide enhanced security, prevent damage by pets, and will help keep your loved ones on the safe side.

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 assist you with your BAL rating and your window, door and screen requirements to ensure your home meets the code.

Learn more about BAL Ratings and construction requirements here.

Window Restrictors

In 2013 the Australian Building Code ruled that some upper-level windows require opening restrictors to prevent the window being opened more than 125mm. Similarly, windows leading to pools or waterways are required to be fixed in such a way that the window is not capable of opening more than 100mm.

These opening restrictions are in place to protect children’s safety, but what if you want more fresh air in your home without compromising safety?

There is a solution…

With Jason Windows, you can get security screens that meet the safety requirements for pools and falls—and they’re designed to fit your existing Jason frames seamlessly!
