Benefits of Double Glazed Windows for Melbourne Homes

Insulation and Energy Efficiency

Double glazed windows have two panes of glass instead of just one. This extra level helps insulate your house against temperature fluctuations and excess noise. Using double glazed windows can make your home more comfortable, and by keeping your home’s temperatures more stable, double glazed windows can help with your energy bills as well.

Victoria’s climate can go from very cold in winter to very hot in summer. Rylock Windows & Doors’ double glazed windows are manufactured to meet the extremes of the Australian climate. Double glazed windows help your house to maintain its temperature, keeping your rooms cool in summer and warm in winter.

Climate Protection

When you commission a Rylock Windows & Doors double glazed window, we work with you to establish the level of climate protection your windows require. This depends on a number of factors, including the direction your window is facing, the amount of shade covering the window and your building’s Bushfire Attack Level (BAL). We do this to make sure your custom-made double glazed window is the perfect fit.

Noise Reduction

Windows that are double glazed not only keep out outside heat, they also reduce the amount of outside sound entering your home, business or studio. Aeroplanes, barking dogs, street traffic, foot traffic, noisy neighbours or your own air-conditioning unit, whatever the noise, a double glazed window can help insulate your room against it.


With Grade-A safety glass, Rylock Windows & Doors’ double glazed windows are thicker and harder to break. Not only do they keep temperatures in, but they also keep burglars out. Special installation techniques mean that the glass is seamlessly embedded in the window, making it much harder to pop out.

When you order a Rylock Windows & Doors double glazed window, you can customise its level of security further by choosing from a range of single lock, dead latch and patio bolt options.
