Secondary glazing for listed and roadside Leicester homes
Between the A6 and A47 corridors, the inner ring road and the New Walk conservation area, Leicester has a steady flow of homeowners looking for a serious noise reduction without touching the original sash. Secondary glazing is the option Leicester City Council conservation officers usually accept, and Legacy Windows matches you with three specialists who quote a fixed price on the same brief.

Frequently asked questions
Does secondary glazing work on ring-road traffic noise? Yes. A 100 to 150 mm cavity between the original sash and the secondary pane, with 6 mm acoustic laminated glass on the inner unit, cuts most passing traffic noise. It is the standard specification our panel offers for LE1 and LE2 addresses close to the inner ring road.
Do I need Listed Building Consent for secondary glazing in New Walk? Usually no, because the original frame is not touched. Leicester City Council conservation officers commonly recommend secondary glazing on New Walk townhouses for exactly that reason. A short call to the conservation team confirms.
Can I open the sash behind the secondary unit? Yes on hinged and horizontal-slider secondary units. Vertical sliders and side-opening designs both allow full access to the original sash for cleaning and ventilation.
