Security double-glazed units in Dover

What should security double-glazed units cost in Dover?

Guide prices for security double-glazed units in Dover 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.

What you can specify

Warm-edge spacer bars in black, grey or white
Security glazing tape or clips where beads are external
Low-E coating and argon fill for insulation
24 mm, 28 mm and other overall thicknesses to suit frames

Kent ranges from Canterbury's listed city centre and the Regency fronts of Tunbridge Wells to the Medway towns, Ashford's growth estates and coastal Margate and Folkestone.

Good candidates for security double-glazed units:

Patio doors and bifolds
Glazed back and side doors
Windows in flats on walkways and balconies
Replacing misted or damaged units

Before the glass is ordered

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.

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 Dover: questions

Do you cover Folkestone as well as Dover?

Yes. As well as Dover, we can arrange surveys in nearby Folkestone, Deal and Canterbury. 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.

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.
