Secondary glazing for Glasgow’s B-listed tenements and West End conservation flats
Secondary glazing is often the only sensible warmth-and-quiet upgrade on a Glasgow sandstone tenement — many are B-listed, Glasgow West and Pollokshields are conservation areas, and Historic Environment Scotland actively prefers reversible internal panels over sash replacement. A discreet aluminium secondary system keeps the original sash-and-case intact while cutting heat loss around 60% and noise from Great Western Road, Byres Road or Pollokshaws Road by 45-50dB. Legacy Windows is a quote comparison service that matches you with vetted secondary glazing installers.

Frequently asked questions
Will Historic Environment Scotland approve secondary glazing on a B-listed tenement? Almost always yes. Because it is fully reversible and does not alter the original sash-and-case, HES and Glasgow City Council treat secondary glazing as the preferred energy-efficiency route on listed tenements. Consent is still required, but decisions are usually straightforward when slim aluminium frames matching the sash sub-divisions are used.
Does it work against Byres Road or Great Western Road noise? A 100-150mm air gap combined with 6.4mm acoustic laminate typically drops external noise by 45-50dB — enough to make Byres Road, Great Western Road and Pollokshaws Road bedroom facades genuinely quiet at night.
Typical prices for a tall tenement sash? Standard horizontal-slider units £310 to £630 supplied and fitted per window; tall tenement vertical-lift units £700 to £835. Acoustic laminate adds £100-£160 per window. A full tenement flat with five sashes usually lands £2,300 to £3,800 total.
