Security double-glazed units in Isleworth: what will it cost?
Our guide range for security double-glazed units in Isleworth 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.
What you can specify
- Made to measure for each sash, light and door panel
- Security glazing tape or clips where beads are external
- Warm-edge spacer bars in black, grey or white
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Low-E coating and argon fill for insulation
- Toughened outer pane where safety glass is required
Fitting in Isleworth and nearby
We arrange surveys and fitting in Isleworth and across the TW7 postcode district, as well as in nearby Hounslow (1 mile) and Heston (2 miles). Dates depend on installer availability.
Greater London has every kind of glazing, from Georgian sashes and Victorian bays in conservation areas to high-street shopfronts, office curtain walling and new-build flats.
Typical settings for security double-glazed units:
- Glazed back and side doors
- Windows in flats on walkways and balconies
- Ground-floor and basement windows
- Patio doors and bifolds
Getting the right glass for your building
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
Internal or external beads
If your beads are on the outside, we add security tape or clips so the unit cannot be lifted out after the beads are removed.
What the rules say in England
Listed buildings and conservation areas
In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.
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.

Security double-glazed units in Isleworth: questions
Do you cover Hounslow as well as Isleworth?
Yes. As well as Isleworth, we can arrange surveys in nearby Hounslow, Heston and Richmond. Dates depend on installer availability.
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.
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.
Can I just replace the glass and keep my frames?
Yes, if the frames are sound. We measure each unit, make security units to the same size and fit them into your existing frames.
