Secondary Glazing for Restaurants
Front-of-house restaurants near main roads live with an acoustic problem that ruins the customer conversation experience — and it's usually the windows. The most common question we get is: "How disruptive is the install?" — the short answer is on this page, alongside the technical detail.

Standard spec for restaurants
Acoustic gain typically drops street-conversation intelligibility to background level.
Front-of-house glazing typically uses fixed lift-out panels — no moving parts to service.
Kitchen and back-of-house use hinged units for emergency egress compliance.
"How disruptive is the install?"
We work overnight from 22:00 and hand back a cleaned trading floor before service.
Common questions
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.
Is there a warranty?
Yes — 10 years on the manufacture and installation, and a manufacturer's warranty on the glass units.
Do you install in flats and communal buildings?
Yes — the install is entirely inside your flat, so freeholder consent is usually straightforward and window-cleaner access to the primary window is unaffected.
What glass thickness do you recommend for main-road noise?
6.4 mm laminated on the secondary as standard, or 6.8 mm where the road carries heavy commercial traffic.
How is the quote calculated?
We survey and template every opening on site, then quote in writing per opening — no per-square-metre pricing that hides oversize charges.
