Laminated security glass in Derry

Laminated security glass in Derry: what will it cost?

As a guide, allow £174 to £594 including VAT (£145 to £495 plus VAT) per pane for laminated security glass in Derry, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.

Laminated security glass is made by bonding two or more sheets of glass to a plastic interlayer, usually PVB, under heat and pressure. When it is struck the glass cracks but the fragments stay stuck to the interlayer, so the pane keeps filling the opening and has to be attacked again and again before anyone can get through.

What you can specify

Single panes or the inner or outer pane of a sealed unit

Getting the right glass for your building

Clear or special glass

Low-iron glass removes the green tint on thick panes, acoustic interlayers cut road noise, and obscure versions give privacy for bathrooms and side panels.

Frame and rebate depth

Thicker laminates need a deeper glazing rebate and stronger beads. We check what your frames will take before anything is ordered.

What the rules say in Northern Ireland

Northern Ireland

Security rules for new homes

If you are building a new home in Northern Ireland, ask the council's building control service which security requirements apply. In existing homes nothing obliges you to upgrade glass, but laminated glass to BS EN 356 P1A in doors and in windows beside them is a common benchmark taken from guidance in Great Britain.

Insurer requirements

Insurers set their own conditions for premises, stock and cash in Northern Ireland, and may name a glazing class in the policy. Get the wording in writing before ordering. The insurer decides whether the glass meets it, and the glass manufacturer's test evidence comes with our quote.

Laminated security glass in Derry: questions

Do you cover Strabane as well as Derry?

Yes. As well as Derry, we can arrange work in nearby Strabane. Dates depend on installer availability.

Will laminated glass fit my existing windows?

Usually. A laminated pane or a sealed unit with a laminated inner pane is made to the same overall thickness as your current glass where the frame allows. We check rebate depth, beads and hinges first.

Can laminated glass be cut to size?

Yes. Unlike toughened glass, laminated glass can be cut after it is made, which helps with odd shapes and quick replacements. The edges are finished and kept dry in the frame to protect the interlayer.

Does laminated glass stop burglars completely?

No glass makes a building impossible to enter. Laminated glass makes breaking in slow, noisy and hard work, which makes the building a much poorer target for an opportunist. Higher classes and stronger frames add more delay.
