On Amelia Street in West Hobart, Tasmania, Sealasash recently completed a retrofit double glazing West Hobart project that delivered both heritage preservation and modern performance. The home featured original timber sashes that were charming in design but inefficient, with thin glass and gaps that let in draughts.
Our team upgraded the clear panes with Vacuum Insulated Double Glazing by Panasonic, a slimline product that dramatically reduces heat loss while fitting into existing window frames. For homes with decorative or stained glass, we partnered with Gavin Merrington – Original Stained Glass who applied a careful techniques we outlined in our article on double glazing lead light with vacuum insulated glass.
To complete the work, we installed full draught and acoustic sealing, blocking air leaks and reducing external noise for year-round comfort.
Why Retrofit Double Glazing Works in West Hobart
West Hobart is known for its heritage homes, but original windows rarely meet modern standards of energy efficiency. Retrofitting advanced glass into existing sashes is a smart alternative to full replacement – preserving character while improving comfort. As we explain in our guide to understanding window performance, upgrading the glazing has one of the biggest impacts on thermal efficiency.
Sealing is equally important. Our Simple Solutions Work article highlights how draught proofing can instantly improve comfort without overcomplicating the process – a step proven effective by studies such as Historic England’s research on draught proofing.
The Result – Comfort Without Compromise
With the new vacuum glass and sealing in place, this Amelia Street property is now:
- Warmer in winter and cooler in summer
- Quieter with reduced outside noise
- Draught-free and energy efficient
- Still showcasing its original heritage timber windows & lead light.
- Windows are repaired to last another 100+ years!
This Amelia Street project demonstrates how retrofit double glazing West Hobart can transform older homes for Tasmania’s climate while maintaining the look and feel that makes them special.
