What is the price of security double-glazed units in Braintree?
Our guide range for security double-glazed units in Braintree is £174 to £594 including VAT (£145 to £495 plus VAT) per unit, including fitting. The survey is free for new installations and your fixed price follows in writing.
A security double-glazed unit is a sealed unit in which one or both panes are laminated glass, usually the inner pane, so the window keeps its insulation but resists being broken through. It fits the same frame as a standard unit and is the simplest way to add security to modern windows and doors.
Glass and fitting options
- Toughened outer pane where safety glass is required
- Security glazing tape or clips where beads are external
- Made to measure for each sash, light and door panel
- Obscure and decorative glass for bathrooms and doors
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Warm-edge spacer bars in black, grey or white
Fitting in Braintree and nearby
From the CM7 district we also cover Witham (7 miles) and Chelmsford (10 miles). Survey dates depend on installer availability.
Essex runs from Chelmsford and Colchester's town-centre retail and Georgian streets to Southend's seafront and large post-war and new-build estates in Basildon and Harlow.
This glazing suits:
- Windows in flats on walkways and balconies
- Ground-floor and basement windows
- Patio doors and bifolds
- Replacing misted or damaged units
Questions we will ask at the survey
Energy performance
Choosing low-E glass, argon and warm-edge spacers keeps the window as efficient as possible, often better than the unit being replaced.
Overall thickness
The new unit must suit the frame's glazing rebate. If your frames only take thin units, we use thinner laminates or adjust the beads.
Building regulations and safety in England
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Security double-glazed units in Braintree: questions
Can you survey in Braintree and nearby towns?
Yes. Surveys in Braintree, Witham and Chelmsford are booked around installer availability.
Do security units reduce noise?
Laminated glass already damps sound better than plain glass, and acoustic interlayers improve it further, which helps on busy roads.
How long do new units take?
Units are made to order after the survey. Lead times vary with glass type and size, and we confirm them when we quote.
Will a laminated unit be heavier?
A little. A laminated pane weighs about the same as a solid sheet of the same thickness. On large opening sashes we check hinges and friction stays.
