Our top 5 things to ask your glazier or window installer when getting a quote for double glazing in Melbourne

If you’re considering double glazing for your Melbourne house, here are the top things to look for:

Thermal Break in Double Glazed Window Frame

Melbourne’s weather can be unpredictable, with temperatures fluctuating throughout the year at any time. A crucial factor to consider when double glazing your home is the presence of a thermal break in the window frame.

A thermal break is a non-metallic, insulating material within the frame that helps prevent the transfer of heat or cold between the inside and outside of your home. It effectively minimises heat loss during winter and keeps your home cooler in summer, contributing to energy savings and year-round comfort.

Argon-Filled Void Between Glass Panes

The space between the two panes of glass in double glazing isn’t just empty; it’s typically filled with inert gases like argon. Argon is denser than air and has a lower thermal conductivity, meaning it reduces heat transfer more effectively.

When considering double glazing options, ensure that the void between the glass panes is filled with argon gas. This feature enhances the insulation properties of your windows, improving energy efficiency and helping to maintain a consistent indoor temperature.

It’s also worth mentioning that we have access to a brand new glass technology that uses a vacuum instead of a gas. Gas can unfortunately, leak over time. Whereas vacuum insulated double glazing actually out performs traditional triple glazing – you can learn more here.

A typical UPVC double glazing is common in Melbourne, so are aluminium double glazed windows.

Low-E Glass Coating

Low-emissivity (Low-E) glass is another essential feature to look for when double glazing your Melbourne home. Low-E coatings are thin, transparent layers applied to the surface of the glass.

They help to reflect heat back to its source, whether it’s the sun in summer or internal heating in winter, while still allowing natural light to enter your home. This reduces the amount of heat that enters or escapes through your windows, making your home more energy-efficient and comfortable year-round.

Quality Draught Seals For Double Glazed Windows (AND DOORS!)

Proper sealing is vital to the overall effectiveness of double glazing. Ensure that the windows you choose come with high-quality seals to prevent air leakage and moisture ingress. Faulty seals can compromise the insulation properties of your double glazing, leading to energy loss, condensation buildup, and potential damage to your home’s interior.

Investing in windows with durable seals and gaskets will not only improve energy efficiency but also prolong the lifespan of your double glazing system. This is particularly important for old timber and wooden windows where draught and acoustic seals can make all the difference in the energy efficiency of the overall window.

It’s often more important to focus on the draught seals before tackling the glass – you can learn more here.

Professional Installation

Even the highest-quality double glazing won’t perform optimally if it’s not installed correctly. When selecting a double glazing provider in Melbourne, prioritise companies with a reputation for professional installation services.

Experienced installers will ensure that your windows are fitted correctly, with proper insulation and airtight seals. This not only maximises the energy-saving benefits of double glazing but also minimises the risk of issues such as drafts, water leaks, and condensation problems which can lead to more expensive repairs.
