In February 2025, Sealasash completed a landmark retrofit double glazing Hobart project, installing 22.97m² of 8.1mm Toughened Glavenir Vacuum Glass by Panasonic across 28 window panes in a beautiful Tasmanian home.
This wasn’t just another retrofit job. The project was so significant that a representative from Panasonic travelled from Japan to Hobart to see it first-hand — underscoring the importance of bringing Glavenir Vacuum Glass technology to Australia.
The house originally relied on outdated 4mm single glass, leaving it draughty, inefficient, and costly to heat through Hobart’s cold winters. Today, with advanced vacuum glass seamlessly retrofitted into the existing timber windows, the property stands as a comfortable, quiet, and energy-efficient home that balances heritage charm with cutting-edge performance.
