Looking for secondary glazing in Slough? S&K Glazing has been installing across Berkshire 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. For Slough properties near Heathrow Airport (LHR), we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
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.
Slough sits directly under Heathrow's western flight paths — extreme aircraft noise affects nearly every property in SL1, SL2 and SL3. Our acoustic glazing is the dominant install locally. Many properties qualify for Heathrow's noise insulation grant scheme.
For acoustic glazing in Slough, aircraft noise from Heathrow Airport (LHR) shapes the brief — overhead noise here regularly exceeds 90 dB at peak times. 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 SL1, SL2 and SL3 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.
