Exciting offers from Duo Glass.

Cut the heat and noise from your home.

Did you know that regular windows in the home lose around 60% of a home’s cool in summer and 70% of a home’s heat in winter, compared to double-glazed windows?

Additionally, double glazing can cut unwanted noise by up to 80%, which is perfect if you live on a busy road or have noisy neighbours.

How can double glazed windows have such a big impact?

  • Thicker glass: Double glazed windows have 6mm glass vs. 3mm (in standard windows). And there are 2 panes of glass, vs. 1 pane in standard windows
  • Argon filled; The argon gas, trapped between the double layers of glass, have insulating properties
  • Sealed; The windows and frames have airtight seals, which stop air leaks and drafts

But, not all double glazed windows are created equal. They may look the same on the outside, but DuoGlass’ product is far superior to those offered in Perth. 

And you can also check our gallery page, which includes some recent work and our before/after images.
