Retain the Frames & Changes the Panes

Vacuum insulated double glazing can mean that you can retain your frame due to its 6.1mm cross section fits perfectly into any frame!

Unfortunately some marketing used by replacement window companies and the double glazing industry can lead home owners to the conclusion that they must replace their wooden windows to gain energy efficiency and improve comfort.  

Nothing could be further from the truth. 

Have you thought about retrofitting to your existing wooden windows?

Retrofitting with Glavenir vacuum insulated double glazing is the answer to obtain 21st century performance for your existing wooden windows. This glass is only 6.1 mm thick and gives triple glazing performance because of the technology which was developed by Panasonic. It beats all double glazing in Australia.

A whole list of other advantages also spring to mind if you retrofit Glavenir vacuum double glazing:

  • The originality and architectural characteristics of the home are kept because of the thin 6.1mm section of glass
  • Heritage can be protected but upgraded discretely allowing older homes to be maintained and lived in with ultra modern comfort
  • Saving old growth wood in better built frames/sashes that provide excellent thermal efficiency over aluminium and plastic
  • Less waste to landfill compared to having replacement windows
  • Less cost because often replacement windows cause other damage not factored into their price (architraves, plaster and outside sealing to walls need extra work after new windows are installed)

A typical Australian style of home that can benefit from Glavenir vacuum double glazing is the 1960’s wooden clad building with fixed panes and awning opening sashes. Recently we were approached by Gen who lives in such a home and she wanted to improve comfort and energy efficiency but not alter the home’s integrity and design.



The results speak for themselves with the client giving a 5 star review for our service:
