Looking for secondary glazing in Northampton? S&K Glazing has been installing across Northamptonshire 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.
Northampton's NN postcodes mix Victorian terraces, post-war estates and new-build developments — all driving consistent demand for window replacement and glazing upgrades. We cover the town and surrounding areas including Daventry and Kettering.
For acoustic glazing in Northampton, 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 East Midlands roads.
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.
