Security Glazing in Sheffield
Around The Peace Gardens and the wider Sheffield conservation stock we install security glazing systems that a second locked barrier on every vulnerable window without altering the original joinery. If your property is in Nether Edge or one of the neighbouring streets, the room-side install typically clears consent without difficulty.

How our security glazing works in Sheffield
The laminated-glass upgrade holds together even when the outer pane fails, defeating the smash-and-grab technique that gets past standard toughened glazing.
For insurance-mandated upgrades we can supply the certification wording your insurer needs alongside the installation.
Most opportunistic break-ins are abandoned inside 60 seconds if entry isn't quick — a key-locked secondary unit adds a second frame, a second pane and a second lock, enough delay to make the target unattractive.
Multi-point locking and anti-jemmy interlocks are available on every hinged and sliding unit; key-locking handles are standard on ground-floor specifications.
Best-fit windows in S1–S17
Ground-floor sashes — common across Sheffield's victorian and edwardian terraces on the west side.
Rear-of-house commercial windows — common across Sheffield's victorian and edwardian terraces on the west side.
Accessible flat-roof windows — common across Sheffield's victorian and edwardian terraces on the west side.
Insurance-flagged openings — common across Sheffield's victorian and edwardian terraces on the west side.
"How does this compare to a laminated pane in a new double-glazed unit?"
A double-glazed unit gives you one lock and one frame; secondary glazing adds a second lock and a second frame — a genuine second line of defence.

Common questions
Can it be insurance-rated for security?
Yes — key-locking handles, multi-point locks and EN 356 P2A/P4A laminated glass options are available on every unit.
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.
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.
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.
Does it help with train and tram rumble?
It's very effective — the low-frequency energy is absorbed by the air-gap decoupling. A mismatched pane thickness widens the acoustic dip that train rumble usually punches through.
