Security double-glazed units in Carlisle: what will it cost?
Expect £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Carlisle. The written quote names the glass makeup, the price and the lead time before you commit.
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
- Obscure and decorative glass for bathrooms and doors
- Toughened outer pane where safety glass is required
- Made to measure for each sash, light and door panel
- Warm-edge spacer bars in black, grey or white
- Low-E coating and argon fill for insulation

Getting the right glass for your building
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.
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.
What the rules say 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 Carlisle: questions
Do you cover Penrith as well as Carlisle?
Yes. As well as Carlisle, we can arrange work in nearby Penrith. Dates depend on installer availability.
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.
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.
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.
