Looking for secondary glazing in Douglas? S&K Glazing has been installing across Isle of Man 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.
Douglas — capital of the Isle of Man — combines Victorian seafront terraces along Loch Promenade with modern financial-sector commercial premises in the centre. Coastal weatherproofing and commercial glazing for the financial services sector dominate our Isle of Man workload across IM1-IM4.
For acoustic glazing in Douglas, aircraft noise from Isle of Man Airport (IOM) shapes the brief — overhead noise here carries notably during quieter parts of the 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 IM1 and IM4 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.
