About toughened glass table top in Derby
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.
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.
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.

Derby at a glance
- Postcodes covered
- DE1, DE22, DE23 and the surrounding area, including Belper, Ilkeston and Heanor
- Coast
- Derby is well inland, around 97 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Derby the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.3 hours of daylight, rising to about 60° and 16.7 hours in midsummer. Strong sun on large glass panels can cause glare and fade furniture behind them. Tinted, solar control or low-iron toughened glass each change how much light, heat and colour come through, so orientation is worth considering when choosing.
- Access and setting
- In flats and city buildings, large panels of safety glass may need to fit through narrow stairs, lifts and doorways. Measuring access routes at the survey avoids problems, and laminated glass suits ground-floor doors and screens facing the street.
- Rules in 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.
Options to choose between
Toughened laminated glass
Toughened sheets laminated together, combining strength with post-breakage retention, often used for frameless panels and higher-load applications.
Holes and cut-outs
Drilled holes for handles, hinges and fixings, and cut-outs for sockets, all made before the glass is toughened.
Clear toughened glass
Heat-treated float glass that breaks into small, blunt pieces, for doors, screens, tabletops and shelves in a range of thicknesses.
Safety Glass in Derby: questions
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.
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.
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.
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.
