What should security double-glazed units cost in Bolton?
Guide prices for security double-glazed units in Bolton 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.
Glass and fitting options
- 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
- Made to measure for each sash, light and door panel
- Low-E coating and argon fill for insulation
- Warm-edge spacer bars in black, grey or white

Before the glass is ordered
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.
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.
Glazing rules in England
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 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 Bolton: questions
Can you survey in Bolton and nearby towns?
Yes. Surveys in Bolton, Farnworth and Westhoughton are booked around 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.
Can I just replace the glass and keep my frames?
Yes, if the frames are sound. We measure each unit, make security units to the same size and fit them into your existing frames.
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.
