Double Glazed Windows – No Match For Secondary Glazing

IMPORTANT: Don’t commit to double glazing windows until you’ve read this.

Once upon a time, double glazed windows were the standard solution for soundproofing to reduce unwanted noise, block or eliminate drafts & reduce heat loss or transfer through windows to reduce heating or cooling costs.

Are you on a busy street? Double-glazed windows and doors do keep out the noise.

Freezing in the dead of winter? Double-glazed windows do keep in the heat.

But, although efficient, the replacement of perfectly good windows followed by the installation of completely new double-glazed windows is costly & disruptive, to say the least.

At Sound Proof Windows, we’ve come up with a solution at less than 50% of the cost of an average double glazed window, & they can be installed typically in one hour per window.

Not only does it save you money & is quicker & less disruptive to install but the soundproofing & draft reduction results are far superior!

It’s called secondary glazing, where we retrofit a second window to the inside of your existing window.

Why is retrofitting cheaper than double glazing?

To upgrade existing windows to double glazing means ripping out the original windows and installing completely new double-glazed windows.

With secondary glazing we install a new window on the room side of your existing window to create double glass windows.

You get to keep your existing windows as we simply fit a new window over them, giving you double-glazed soundproof windows whilst you’re only paying for one new pane of glass rather than two.

And, if you want to know just how cheap our secondary double glazed windows are or ‘How much are retro-fitted secondary double glazed windows?‘, simply go to our Double Glazed Windows Costs page where we list costs per meter for various window types.

Why does secondary glazing perform better?

It’s all about the gap – physics tells us and tests verify, that the larger the air gap between the panes of glass, the better the reduction of sound and energy transferring through the glass.

Double glazing only provides a very thin air gap as compared to secondary glazed windows, and, as a result, provides far less effective soundproofing & window insulation.

Also, when we install the secondary window, we completely seal the secondary window frame, providing you with an additional barrier blocking noise, heat transfer & drafts. With traditional double glazed windows, gaps can remain around the frame defeating the purpose of the expenditure.

Will Double Glazing Windows alter the look of my home?

The installation of new double glazing in Melbourne homes generally requires the removal of the existing windows. With retrofitting or secondary glazing, you keep your original windows and subsequently the original feel of your home. So, as a result, it’s even possible to have double glazing on existing aluminium windows thru to classic older style lead light windows!

And remember, if you have a heritage listed home or in some body corporate situations, you may not be able to install traditional double glazing. Secondary glazing can bypass any restrictions as the external appearance of your property does not change.

Sounds too good to be true. What’s the Catch?
