Toughened & Laminated Safety Glass
Safety glass is glass made to reduce the risk of injury if it breaks: toughened glass breaks into small, relatively blunt pieces, while laminated glass is held together by a plastic interlayer. It is needed in doors, low-level panes and other critical locations, and for tabletops, shelves, screens and cabinets.

How our safety glass service works
We supply and fit toughened and laminated safety glass made to measure for doors, door side panels, low-level windows, internal screens, tabletops, shelves, cabinet doors and glass panels. A glazier surveys or takes your measurements, confirms the thickness, edge finish and any holes or cut-outs, and checks whether the location needs a particular safety class. You then get a written quote that fixes the price for the specification shown. The glass is cut and worked before it is toughened or laminated, then delivered or fitted by our glaziers. Every piece of safety glass for a building location carries a permanent mark showing the standard it meets.

Options to choose between
Clear toughened glass
Heat-treated float glass that breaks into small, blunt pieces, for doors, screens, tabletops and shelves in a range of thicknesses.
Laminated safety glass
Two or more sheets bonded with an interlayer that holds broken glass in place, for overhead, security and fall-risk locations.
Toughened laminated glass
Toughened sheets laminated together, combining strength with post-breakage retention, often used for frameless panels and higher-load applications.
Low-iron glass
Extra-clear glass with much less green tint, chosen for tabletops, shelving and panels where colour and edge clarity matter.
Satin or obscure finish
Acid-etched or patterned glass for privacy in doors and screens, toughened or laminated to meet safety requirements.
Polished edges
Smooth, clear edges for exposed glass on tables, shelves and frameless panels, safer to handle and neater to look at.
Holes and cut-outs
Drilled holes for handles, hinges and fixings, and cut-outs for sockets, all made before the glass is toughened.
Heat soak testing
An extra heat test after toughening that reduces the risk of spontaneous breakage from nickel sulphide inclusions in the glass.
Good to know about safety glass
Toughened glass is ordinary float glass that has been cut to size, heated and then cooled quickly with jets of air. This leaves the surfaces in compression, making it several times stronger than untreated glass of the same thickness. When it does break, it crumbles into small, relatively blunt pieces.
Once glass has been toughened, it cannot be cut, drilled, notched or edge-worked. All shaping, holes for handles or hinges, and cut-outs for sockets must be finished on the float glass first. This is why accurate measuring and templates matter before any order is placed.
Laminated glass is two or more sheets bonded with a plastic interlayer, often PVB. If it breaks, the pieces stick to the interlayer and the pane stays in place. That makes it useful for overhead glass, ground-floor security and openings where an empty hole would be a risk.
In England, Approved Document K requires safety glass in critical locations: glass in a door or within 300mm of a door edge, up to 1500mm above the floor, and other glass within 800mm of the floor. The rules are similar elsewhere in the UK, but the detail differs.
BS EN 12600 classifies safety glass by a pendulum impact test, with class 1 the highest and class 3 the lowest. In England, critical locations generally need at least class 3, and door or side panels wider than 900mm need class 2 or better.
Safety glass in a building should carry a permanent mark, usually in a corner, that stays visible after fitting. It names the maker or supplier and the standard, such as BS EN 12150 for toughened glass. The mark is how a buyer or inspector can confirm what was fitted.
Edge finish affects both look and safety. Arrised edges are lightly sanded to take off sharpness and suit glass held in frames. Polished edges are smooth and clear for exposed edges on tables, shelves and frameless panels. Bevelled edges add a decorative angled border.
Toughened glass can, in rare cases, break without any obvious impact because of tiny nickel sulphide inclusions in the glass. Heat soak testing exposes the toughened glass to heat for a set period to break susceptible panes before supply, which reduces the risk without removing it completely.
Glass tabletops and shelves need the right thickness for the span and load. Thicker glass deflects less, so a long shelf or a large table needs a heavier panel than a small side table. The supplier confirms a suitable thickness for the use, not just the size.
The price of safety glass depends on its size, thickness, whether it is toughened or laminated, the edge finish, the number of holes and cut-outs, any shapes or curves, and whether it is supplied only or fitted. Low-iron or tinted glass costs more than clear float.
Low-iron glass removes most of the slight green tint that ordinary clear glass shows at its edge and through thick panels. It suits tabletops, display shelves and splashback-style panels where true colours and a clearer edge matter.
When measuring for a replacement panel, measure the opening or old glass in at least two places for width and height, and note the thickness. For anything with holes, curves or angled corners, a hardboard or card template gives the most reliable result.
Rules and regulations
Building regulations differ between the four UK nations. Here is what usually applies to safety glass; your written quote confirms the detail for your property.
England
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
Wales
In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.
Security rules for doors and windows differ between the UK nations. For replacement doors and windows in Wales, products tested to PAS 24 are a sensible benchmark.
Scotland
Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.
Security standards for doors and windows apply to new homes in Scotland; for replacements, PAS 24 products are a sensible choice.
Northern Ireland
Technical Booklet V covers safety glazing in Northern Ireland, including glass in and around doors and low-level glazing where people could walk into it.
For replacement doors and windows in Northern Ireland, PAS 24 products are a sensible choice for security.

Safety Glass questions
What is the difference between toughened and laminated glass?
Toughened glass is heat treated so it is stronger and, if broken, crumbles into small, relatively blunt pieces, leaving the opening empty. Laminated glass is sheets bonded to an interlayer, so when it breaks the pieces stay stuck in place. Both can be safety glass. Laminated is preferred where falling glass or an open hole would be a hazard.
Can toughened glass be cut or drilled after it is made?
No. Toughened glass cannot be cut, drilled or edge-worked once it has been toughened, because any damage to the surface releases the internal stress and the whole pane shatters. All sizes, holes and cut-outs must be finalised before toughening. That is why accurate measurements or a template are needed before the order is placed.
Where is safety glass required in a house?
In England, safety glass is needed in critical locations: glass in doors and within 300mm of a door edge, up to 1500mm above floor level, and other glass within 800mm of the floor. Small panes and leaded lights have specific exceptions. The rules elsewhere in the UK are similar, but the detail differs between nations.
How do I know if my glass is safety glass?
Look for a permanent mark etched or printed in a corner of the pane. It should name the maker or supplier and the standard, such as BS EN 12150 for toughened glass, or show a BS EN 12600 class. Older glass may have no mark. If you are unsure, a glazier can check and advise.
What thickness of toughened glass do I need for a table or shelf?
It depends on the size, how the glass is supported and the load it will carry. Small side tables can use thinner glass, while large dining tables and long shelves need thicker panels to limit bending. Tell us the dimensions, support method and what it will hold, and we will confirm a suitable thickness in the quote.
How much does toughened glass cut to size cost?
The price depends on the dimensions, thickness, glass type, edge finish, number of holes and cut-outs, any shapes, and whether you want supply only or fitting. Laminated, low-iron and obscure glass cost more than clear toughened. See the guide prices for typical panels, then get a written quote for your exact specification.
Why do I need to wait for toughened glass?
Toughened glass is made to order. Each panel is cut, edge-worked and drilled from float glass, then heated and cooled in a toughening furnace. It cannot be cut from stock once toughened. Your written quote shows the expected timescale, and the glazier will confirm fitting arrangements once the glass is ready.
Can toughened glass break on its own?
Rarely, yes. Tiny nickel sulphide inclusions in the glass can expand over time and cause a toughened pane to break without an obvious impact. Edge damage during fitting can also cause later failure. Heat soak testing reduces the risk of inclusion-related breakage, and careful handling and correct fitting protect the edges.
Should I choose a polished or arrised edge?
Choose polished edges where the edge will be seen or touched, such as tabletops, shelves and frameless panels, because they are smooth and look neat. Arrised edges are lightly sanded to remove sharpness and are fine where the edge sits hidden in a frame. Bevelled edges are decorative and suit mirrors and some tabletops.
Is laminated glass better for security?
Laminated glass usually gives better security than toughened glass of similar thickness, because the interlayer holds the glass together after it cracks, so making a hole takes more effort. Thicker interlayers and multi-layer laminates give more resistance. For ground-floor windows, shopfronts and doors, laminated glass is often chosen for this reason.
