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.

Questions we will ask at the survey

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.

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.

Building regulations and safety in England

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.

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 double-glazed units in Walthamstow: questions

Do you cover Leytonstone as well as Walthamstow?

Yes. As well as Walthamstow, we can arrange surveys in nearby Leytonstone, Tottenham and Woodford Green. 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.

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.
