Safety glass for doors in Harrow: what to know
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.
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.
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.
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.
Included as standard

About Harrow for this job
- Postcodes covered
- HA1, HA2, HA3, HA5, HA7 and the surrounding area, including Wembley, Northolt and Greenford
- Coast
- Harrow is well inland, around 50 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Harrow the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 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.
Specification choices
Low-iron glass
Extra-clear glass with much less green tint, chosen for tabletops, shelving and panels where colour and edge clarity matter.
Clear toughened glass
Heat-treated float glass that breaks into small, blunt pieces, for doors, screens, tabletops and shelves in a range of thicknesses.
Holes and cut-outs
Drilled holes for handles, hinges and fixings, and cut-outs for sockets, all made before the glass is toughened.
Safety Glass in Harrow: questions
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.
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.
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.
