Historic and listed properties are full of character — and protecting that character is both a responsibility and a legal requirement. But when your original windows leave you battling draughts, noise and condensation, what can you do?
Thankfully, secondary glazing offers the perfect solution — and it’s often recommended by planning authorities for exactly this reason.
For listed buildings and properties in conservation areas, making changes to original windows can be strictly controlled. Replacing them entirely may be restricted, costly, or simply impossible without consent.
But while timber sash windows and other original styles are beautiful, they’re often poor insulators. That means higher energy bills, more condensation, and greater noise intrusion — especially in city or roadside locations.
Secondary glazing is installed on the inside of your existing window, creating a discreet second pane without altering the external appearance of the property.
Because it doesn’t interfere with the original frames or structure, it usually doesn’t require planning permission — and it’s fully reversible, making it conservation-friendly.
In fact, Historic England supports secondary glazing as a way to improve thermal performance without compromising heritage values.
At Purely Glazing, every unit is made to measure — ensuring a slim, neat finish that’s barely noticeable once installed. Whether you’re dealing with sash windows, arched frames or uniquely shaped panes, we can create a secondary glazing solution to match.
If you’re struggling with the cold or tired of outside noise, there’s no need to compromise your home’s style or history. With secondary glazing, you can have warmth, peace, and security — all while respecting the original features of your property.
