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.

Things to decide before you order
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.
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
Rules that apply 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 New Malden: questions
Do you cover Surbiton as well as New Malden?
Yes. As well as New Malden, we can arrange surveys in nearby Surbiton, Morden and Wimbledon. Dates depend on installer availability.
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.
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.
