What should security double-glazed units cost in Truro?

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
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Security glazing tape or clips where beads are external
- Toughened outer pane where safety glass is required
- Obscure and decorative glass for bathrooms and doors
- Made to measure for each sash, light and door panel
- Warm-edge spacer bars in black, grey or white

- Glazed back and side doors
- Ground-floor and basement windows
- Patio doors and bifolds
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.
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.
Glazing rules 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.
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 Truro: questions
Which areas near Truro do you cover?
We can arrange work in Truro and in nearby Falmouth (8 miles), Redruth (8 miles) and Newquay (10 miles). 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.
