Retrofit Double Glazing Brighton – Dendy Street Heritage Upgrade

Sealasash completed a retrofit double glazing Brighton project on Dendy Street, upgrading sash windows with Panasonic vacuum glass and draught sealing while preserving leadlight features.

On Dendy Street in Brighton, Sealasash recently delivered a retrofit double glazing Brighton project that combined heritage detail with modern performance. The property featured beautiful double-hung sashes with leadlight panels in the top sash – windows full of character but struggling with thermal efficiency.

We carefully upgraded the existing clear panes with Vacuum Insulated Double Glazing by Panasonic, keeping the leadlight intact while dramatically improving insulation. To complete the work, our team installed full draught and acoustic seals, eliminating unwanted air leaks and reducing external noise.

Balancing Character and Comfort

Brighton homes often showcase unique architectural details, but original windows rarely meet modern performance needs. This project shows how retrofit glass can protect heritage features like leadlight panels while providing the comfort of advanced vacuum technology. Small improvements, such as sealing gaps, also play a crucial role – something we explain further in Simple Solutions Work.

Results of Retrofit Double Glazing in Brighton

With the new vacuum glass and draught sealing complete, this Dendy Street home now benefits from:

  • Better insulation without altering the appearance of the windows
  • A quieter, more comfortable living environment
  • Protection for delicate leadlight features found out more about this process here
  • Improved thermal efficiency suited to Brighton’s climate

This project highlights how retrofit double glazing Brighton homes can achieve both character preservation and modern comfort in one solution.
