Security double-glazed units in Greater London

What is the price of security double-glazed units in Greater London?

Our guide range for security double-glazed units in Greater London 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.

Questions we will ask at the survey

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.

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.

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.

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 double-glazed units in Greater London: questions

Which towns in Greater London do you cover?

We can arrange work anywhere in Greater London, including Central London, Islington, Bexley, Barking and Archway, and in other towns across the area.

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.

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.

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.
