Toughened glass table top in Letchworth Garden City
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.
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.
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.
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.

- Coast
- Letchworth Garden City is well inland, around 70 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Letchworth Garden City the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 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
- Older rural homes often have internal doors and screens with old, unmarked glass. Upgrading them to toughened or laminated safety glass is common, and timber door frames may need careful beading when the new glass is fitted.
- 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.

Choosing your safety glass
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.
Laminated safety glass
Two or more sheets bonded with an interlayer that holds broken glass in place, for overhead, security and fall-risk locations.
Safety Glass in Letchworth Garden City: questions
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.
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.
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.
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.
