Security double-glazed units in Welling

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

Guide prices for security double-glazed units in Welling are £174 to £594 including VAT (£145 to £495 plus VAT) per unit for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.

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

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

Questions we will ask at the survey

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.

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.

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 Welling: questions

Which areas near Welling do you cover?

We can arrange work in Welling and in nearby Bexley (2 miles), Eltham (3 miles) and Thamesmead (3 miles). Dates depend on installer availability.

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.

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.
