Double Glazed Windows are windows that contain two panels of glass separated by air or a non-toxic gas called Argon.

The gap between the glass panels can potentially have a significant impact on heat transfer from the outside of your home to the inside, and vice versa. And depending on the glass combinations being used with your Double Glazing, it can also have an impact on noise reduction inside and outside your home.

Now that we’ve covered the basics, let’s take a moment to consider how Double Glazed Windows might suit your home and your budget.

Jason Windows uses Argon gas because it is more effective than air when preventing heat transfer due to its increased density and reduced thermal conductivity.

Argon gas (better than air at preventing heat transfer) 3. Spacer (separates the panes of glass and helps seal in Argon gas) 4. Dessicant (absorbs moisture) 5. Seal (responsible for keeping insulating Argon gas in, and humidity out)

Why Choose Double Glazing?

Double Glazed Windows offer three benefits that distinguish it from your typical glass window. These are:

  1. Noise reduction
  2. Thermal comfort
  3. Energy efficiency

Noise Reduction

Noisy neighbourhoods can be an issue. Fortunately, with the right combination of glass options, Double Glazing helps limit these noisy interruptions by absorbing soundwaves to give you a quieter, more comfortable home.

Double Glazing also works when the circumstances have been reversed—on movie night, for instance. With Double Glazing you can turn the volume up and still be a considerate neighbour.

  • Choosing the right glass for noise reduction: The effectiveness of noise reduction depends on the types of glass used in your Double Glazing Unit (DGU). Book a glass consultation for help selecting the best combination for noise reduction.

The right choice of glass in your double glazing unit can help reduce traffic noise from a busy street. Book a glass consultation to find out more.

Thermal Comfort

It is estimated that 40% of a home’s heating energy can be lost, and 87% of its heat can be gained through its windows. https://www.yourhome.gov.au/passive-design/glazing. With Double Glazing, heat regulation becomes easier and more stable.

Energy Efficiency

Due to the temperature regulation that Double Glazing provides, you don’t have to use as much power to beat the heat or stay warm. And by using less heating and cooling in your home you can save money on your energy bill. Win, win!
