What should security double-glazed units cost in Northolt?
Budget £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Northolt, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
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.

- Warm-edge spacer bars in black, grey or white

Fitting in Northolt and nearby
Northolt is about 11 miles from Central London, the main centre for Greater London. We can survey and fit across the UB5 district and in nearby places such as Greenford and Harrow.
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.
Good candidates for security double-glazed units:
- Patio doors and bifolds
- Replacing misted or damaged units
- Ground-floor and basement windows
- Glazed back and side doors
Before the glass is ordered
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.
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.
Glazing rules in England
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.
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 Northolt: questions
Which areas near Northolt do you cover?
We can arrange work in Northolt and in nearby Greenford (1 mile), Harrow (3 miles) and Southall (3 miles). Dates depend on installer availability.
Which pane should be laminated?
Usually the inner pane, so smashing the outer pane does not create an opening. On doors and low panes the outer pane is normally toughened to meet safety rules.
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.
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.
