Looking for secondary glazing in Westminster? S&K Glazing has been installing across Greater London for over a decade. Secondary glazing is the ideal solution where you can't replace the primary window — listed buildings, conservation areas, rental properties, and period homes with original sash windows.
Secondary glazing is the ideal solution where you can't replace the primary window — listed buildings, conservation areas, rental properties, and period homes with original sash windows. We install slim, virtually invisible aluminium-framed secondary units behind your existing windows, delivering noise reduction up to 50 dB and a 60% improvement in thermal efficiency, without altering the building's appearance.
Westminster's mix of Georgian terraces, mansion blocks, and prestigious commercial premises requires a glazier with heritage credentials and commercial experience. We've worked across SW1, W1, W2 and WC2 on listed-building secondary glazing, shopfronts on Bond Street and Marylebone High Street, and acoustic upgrades for properties facing busy West End streets.
For acoustic glazing in Westminster, the dominant noise source is usually traffic or rail rather than aircraft — though we still get enquiries from properties on flight approach corridors several miles from the nearest airport. Our standard acoustic double glazing reduces external noise by 38-42 dB, and our triple-glazed asymmetric specifications hit 48-52 dB for properties on the busiest London roads. Most commonly we're working across SW1, W1, W2 and WC2 postcodes.
We measure existing reveal depths and assess the primary window's condition. Our surveys are accepted by listed-building officers and planning departments.
Each unit is made to fit your exact reveal — slim aluminium frames in white, brown, black or RAL-matched colours. Glass options include acoustic laminated and Low-E thermal.
Installed entirely from inside the property with no disruption to the original window. Most installations are completed in a single day.
