Secondary glazing quotes for Birmingham conservation and city-centre flats
Secondary glazing has become a go-to solution for two very different Birmingham markets: listed and conservation properties in Edgbaston, Bournville and the Jewellery Quarter where the primary window cannot be altered, and city-centre apartment conversions in the B1 to B4 postcodes where traffic noise from the ring road drives demand. Legacy Windows is a quote comparison service that shortlists firms specialising in reversible internal units.

- Every quote separates frame, glass, brushes and installation for line-by-line comparison
Areas we cover around Birmingham
Demand is heaviest in the Jewellery Quarter (B1), Digbeth (B5), Edgbaston (B15) and Bournville, plus mansion-block conversions across the city centre. Cross-border briefs come from Solihull, Wolverhampton, Coventry and Sutton Coldfield, particularly on listed properties where a UPVC replacement window would never receive consent.
Frequently asked questions
Does secondary glazing need Listed Building Consent in Birmingham? Usually yes on a Grade I or II listed building, though local authorities recognise it as reversible and low-impact. The application is far simpler than replacing the primary sash or casement. Installers in our network prepare the drawings and heritage statement as part of the quote.
Will secondary glazing satisfy Part L on a listed Jewellery Quarter conversion? Listed buildings are largely exempt from Part L where full compliance would harm the historic fabric. Secondary glazing typically brings the combined unit down to around Uw 1.7 W/m²K, which is the accepted heritage benchmark used by Birmingham City Council heritage officers.
How much noise reduction can I expect on a Digbeth apartment above the ring road? A 100mm cavity between the primary sash and a 6.4mm acoustic laminate secondary pane delivers around 45dB reduction, which is enough to drop the noise of the Middleway from disruptive to background.
