Laminated security glass in Dorchester

How much does laminated security glass cost in Dorchester?

As a guide, allow £174 to £594 including VAT (£145 to £495 plus VAT) per pane for laminated security glass in Dorchester, 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.

Glass and fitting options

Blocks most UV light, which slows fading of furniture and stock
Classes from P1A to P5A under BS EN 356, with heavier P6B to P8B options
Single panes or the inner or outer pane of a sealed unit
Cut to size on site or in the factory, unlike toughened glass
Clear, low-iron, tinted, obscure and acoustic versions
PVB interlayers from 0.38 mm to 1.52 mm, or stiffer ionoplast interlayers

Things to decide before you order

Single pane or sealed unit

In double glazing the laminated sheet is normally the inner pane, with a toughened outer pane where safety glass is needed. Single-glazed frames take a laminated pane on its own.

Which security class

P2A suits most homes and many offices. Higher-risk shops, stockrooms and cash areas usually move up to P4A, or to the anti-bandit P6B to P8B classes.

Rules that apply in England

England

Replacing glass in an existing frame

Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Safety glass in critical locations

In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Laminated security glass in Dorchester: questions

Can you survey in Dorchester and nearby towns?

Yes. Surveys in Dorchester, Weymouth and Bridport are booked around installer availability.

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.

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.

What does P2A mean on laminated glass?

P2A is a class under BS EN 356. A sample has to stop a 4.11 kg steel ball dropped three times from 3 metres without the ball passing through. It is a sensible minimum for windows and doors that can be reached from the ground.
