Commercial
Secondary Glazing for Offices
Open-plan offices lose the acoustic privacy of cellular working — and every rentable square foot near a window has to earn its rent. Below is the specification we install most often for offices clients, and how we handle single-floor fit-outs or full-building landlord upgrades.
Standard spec for offices
Landlord upgrades qualify for capital allowances as a building improvement.
Whole-floor installs typically complete over a single weekend with the client back in on Monday.
If noise comes through a lightweight spandrel panel, a poorly sealed curtain wall joint or the ceiling void, glazing alone will not solve it and we will say so at survey.
"Will it look industrial in a modern fit-out?"
Satin-anodised slim profiles disappear behind mullion caps in most Cat A fit-outs.

Common questions
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
Do you supply the acoustic performance data insurers ask for?
Yes — every acoustic-specified install ships with a performance report you can hand directly to an insurer or building-control officer.
Will secondary glazing stop conversation-level noise from a neighbour?
Yes — mid-frequency speech is exactly what a laminated secondary pane damps hardest. We'd typically spec 6.8 mm on the secondary and keep the primary as-is.
How long does an install take?
A typical whole-house residential install is a single day; larger commercial jobs are phased so trading isn't interrupted.
How much noise reduction can I realistically expect?
With a 100 mm cavity and 6.4 mm laminated secondary glass we routinely measure 40–47 dB Rw — enough to drop main-road traffic to a soft background hum.
