Retrofit Double Glazing Preserves The Look Of Your Sydney Home

Sydney is blessed with a lot of distinctive older homes. Sometimes, fitting modern window frames to an existing, traditional or heritage design can detract from the very look you’ve come to love. Fitting retrofit double glazing units, retains the look and feel of your home. The streetscape isn’t compromised, but your home becomes a more comfortable place to live. That’s win-win.


Retrofit Double Glazing Uses Genuine Double Glazing- IGU’s

The superior thermal and acoustic insulation properties of the genuine Insulated Glass Units (IGU’s) used in Twinglaze retrofit double glazing comes from a number of factors;

  • the choice of the correct thickness of the two glass sheets
  • the types of glass chosen for the inner and outer panes
  • the vacuum gap between the panes
  • the depth of the gap- specified for your conditions and needs
  • the addition of argon gas to the vacuum to improve thermal insulation

Only real double glazing units have these essential features. Anything less is second best.

But What About ‘Secondary Glazing’?

Let’s be clear (no pun intended). So-called ‘secondary glazing’ is not genuine double glazing. See the last section above…  Secondary glazing fits a second sheet, usually perspex, to the inside of an existing window. These are normally held in place by magnetic strips. We can have a long discussion on the subject, but in essence…

  • secondary glazing does not replace an unsuitable existing window pane.
  • retaining thin existing glass that is a poor insulator of heat and sound, defeats the purpose of getting double glazing
  • being limited by the frame, secondary glazing does not provide the exact gap needed for best performance
  • secondary glazing provides no vacuum gap between the two sheets
  • with secondary glazing, the gap between the sheets is filled with air- a poor insulator
  • with genuine double glazing, the gap is usually filled with argon gas- a superior insulator

There’s no question that secondary glazing is not an improvement on an existing window, but it just can’t perform like genuine double glazing can. Twinglaze gives you superior performance at a surprisingly affordable price.
