Timber retrofit is the most economical approach to achieve genuine double glazing. It typically costs a third as much as replacement with the next most affordable alternative uPVC frames - which are made from plastic.

Supply costs are below; we charge $125/hr for installation assistance on DIY jobs. If you would like us to do the whole job, from start to finish, we will provide a fixed price.


$ 285 /sqm
  • Two sheets of 4mm glass, with a 12mm argon gap.
  • This will more than double the energy efficiency of standard 3mm windows, and significantly reduce noise
  • U 2.5 Thermal Performance Rating (SHGC 0.71, VLT 78)
  • Australian made with an industry leading 10 year warranty
  • This is a great upgrade to single glazing, we normally suggest choosing LightBridge/Optitherm™ glass and reducing the number of windows you choose to double glaze if you are working towards a specific budget for thermal improvement, as the benefits are significant and you can always retrofit the other windows at a later time.
