Retrofit Double Glazing Newham – Heritage Timber Window Upgrade

Sealasash completed a retrofit double glazing Newham project, upgrading timber sash windows with Panasonic Glavenir vacuum glass and draught sealing for modern comfort and efficiency.

In Newham, Victoria, Sealasash recently completed a retrofit double glazing Newham project that delivered modern efficiency while preserving heritage character. The home’s original timber sash windows were carefully upgraded with Glavenir Vacuum Insulated Double Glazing by Panasonic, a cutting-edge glass designed to provide exceptional thermal performance in a slimline profile.

To complete the work, our team installed draught and acoustic sealing throughout the windows. This eliminated air leaks, reduced outside noise, and ensured the advanced glass could perform to its full potential. As outlined in our Simple Solutions Work guide, sealing is one of the most effective ways to improve home comfort without overcomplicating the process.

Results – Comfort Without Compromise

With the upgrade complete, this Newham home now enjoys:

  • A warmer, more efficient interior
  • Draught-free living spaces with improved acoustics
  • Heritage sash windows preserved in their original style
  • Long-term sustainability through advanced glazing technology

This project demonstrates how retrofit double glazing Newham can seamlessly blend modern comfort with the timeless charm of traditional wooden windows.
