Looking for secondary glazing in Lincoln? S&K Glazing has been installing across Lincolnshire 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.
Lincoln's cathedral quarter, steep historic streets like Steep Hill, and Bailgate Georgian conservation drive heritage glazing work across LN1-LN6. Listed-building consents, slim-profile heritage double glazing, and traditional sash window restoration are our main local specialisms.
For acoustic glazing in Lincoln, aircraft noise from Humberside Airport (HUY) shapes the brief — overhead noise here varies through the flight day. Our acoustic specifications start at Rw 38 dB reduction for standard double-glazed acoustic units and scale to Rw 52 dB for triple-glazed asymmetric builds with laminated PVB interlayers. Most commonly we're working across LN1 and LN6 postcodes. We can normally survey within a week and return a proposal showing measured baseline noise alongside the projected indoor level after install.
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.
