Secondary glazing for your traditional sash and casement windows

Secondary glazing is an effective, convenient and cost-effective
way to improve the energy efficiency and noise reduction
capabilities of a primary window. It can even reduce dirt ingress in
the process! Secondary glazing sash windows are the perfect
solution for period properties in any area of London, whether in
Hornsey, Stratford or Notting Hill.

A highly effective, simple-to-install, and more budget friendly than replacement windows

If you are particularly fond of your property’s existing windows: whether they be sliding sash units, Georgian bar windows, or simple casements, you may not be too eager to strip them out and replace them. But it’s no secret that old units can be draughty and cold!

Secondary double glazing provides an extra barrier that can be even more effective than double gazing at keeping your home nice and warm. And what’s more, it is considerably quicker, cheaper and more cost-effective to install, as we will be leaving the existing glazing intact – plus energy efficient windows will save you money in the long run.

We can even provide aluminium secondary glazing, which is slimline, elegant and incredibly robust.

Slimline, discreet, high performing glazing

We manufacture and install special aluminium or hardwood secondary glazing that is both slim and discreet. This comes with either a fully hand painted or sprayed finish.

To make the most of your secondary glazing, we always recommend that the primary windows and doors be upgraded first, if possible.

All round Superb

" I used London Sash Windows and Doors to replace some old timber sash windows. They were superb to deal with, from start to finish. The initial meeting was very efficient. They explained to me that it was not necessary to replace the complete window box, which led to a significant cost saving. The team that arrived on the day were friendly, got the job done swiftly and left my flat cleaner than when they arrived. The windows have substantially reduced noise, the flat is much warmer and my condensation issues are fixed. I wouldn't hesitate to recommend London Sash Windows and Doors to anyone."
