Security double-glazed units in Blackheath

How much do security double-glazed units cost in Blackheath?

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.

Choices you can make

Warm-edge spacer bars in black, grey or white
24 mm, 28 mm and other overall thicknesses to suit frames
Toughened outer pane where safety glass is required
Obscure and decorative glass for bathrooms and doors
Low-E coating and argon fill for insulation
Security glazing tape or clips where beads are external

Things to decide before you order

Which pane is laminated

Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.

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.

Rules that apply in England

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 Blackheath: questions

Which areas near Blackheath do you cover?

We can arrange work in Blackheath and in nearby Greenwich (1 mile), Catford (2 miles) and Eltham (2 miles). 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.

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.
