Cutting list (optional)

Know the sizes? List each pane in millimetres. Toughened glass can't be cut afterwards, so sizes help the glazier quote, but they will still measure up before ordering.

Many people ask whether toughened glass is any different from tempered glass. It is the same product. Toughened is the common name in South Africa and across the Commonwealth. TemperedGlass.co.za is a free quote service. You fill in one form and we pass your request to independent suppliers and glaziers in your area, who quote you directly. We do not sell, toughen or install glass ourselves. There is no fee and no obligation, and you can compare toughened glass suppliers side by side.

Toughened or tempered: the same glass

Toughened glass and tempered glass describe one process, so you may see either word on a quote. Suppliers often say toughened. American sources and many online listings say tempered. Toughened safety glass is simply toughened glass that carries the safety mark.

The key difference is not the name. It is whether a pane is annealed, toughened or laminated, and which type your opening needs.

How glass is toughened, and how it differs from float glass

A processor first cuts the pane to size, then does all drilling, notching and edge work. The glass is then heated in a furnace to about 620 °C and cooled quickly with jets of air. This locks in surface compression.

  • Clear float glass: annealed, cuttable on site, breaks into long sharp shards.
  • Toughened glass: four to five times stronger, breaks into small blunt cubes, cannot be cut afterwards.
  • Heat resistance: toughened glass handles temperature swings much better than float glass.

Toughening does not change the thickness, but it can leave faint roller waves or slight bow. Ask to see a sample if appearance matters.

Choosing thickness and checking quality

Common thicknesses are 4, 5, 6, 8, 10, 12, 15 and 19 mm. Typical uses are 6 mm for splashbacks and shelves, 8 to 10 mm for showers, and 10 to 12 mm for frameless doors. A 5 mm toughened pane suits smaller framed windows and cabinet doors. Your glazier should confirm what suits your opening.

  • Look for the permanent etched safety mark on one corner.
  • Ask about heat-soak testing, which reduces the rare risk of spontaneous breakage from nickel sulphide.
  • Check edges and corners for chips before the pane is fitted.

What affects your quote

Searches for toughened glass prices rarely give a useful answer, because each pane is made to order. We never give prices here. A supplier will consider:

  • The thickness, size and number of panes.
  • The glass type and colour, from clear to low-iron or tinted.
  • Holes, cut-outs and the edge finish.
  • Whether heat-soak testing is needed.
  • Delivery, and whether you want fitting as well.

Send exact sizes and you will get quotes you can compare.

Comparing toughened glass quotes

Glass is made to order once it is toughened, so the details matter. When quotes arrive, check:

  • Exact glass: the type, thickness, colour (clear, low-iron, tinted or frosted) and edge finish, so every quote is for the same thing.
  • Processing: holes, cut-outs, notches and polishing included, all done before toughening.
  • Lead time and delivery: how long processing takes, delivery or collection, and how the panes are packed.
  • VAT and changes: whether VAT is included, how long the price holds and what happens if a size is wrong.

What to include in your request

  • Say whether you want toughened glass or laminated.
  • Give exact pane sizes in millimetres.
  • State the thickness, or what the pane is for.
  • Mention holes, cut-outs and the edge finish.
  • Ask whether heat-soak testing is available.

Frequently asked questions

Does TemperedGlass.co.za sell toughened glass?
No. TemperedGlass.co.za is a free quote service. You send one request and we pass it to independent suppliers and glaziers near you. They contact you directly with a quote. We do not sell, toughen or install glass, and there is no obligation.
Is toughened glass the same as tempered glass?
Yes. Both names describe glass that is heated and rapidly cooled to make it stronger. Suppliers in South Africa usually say toughened, while tempered is common online. The glass is the same, and a toughened safety glass pane carries the same safety mark.
How is toughened glass different from clear float glass?
Float glass is annealed. It can be cut on site and breaks into sharp shards. Toughened glass is four to five times stronger and breaks into small blunt cubes, but it cannot be cut, drilled or polished afterwards. Toughened glass is also better at handling heat.
Can I get a 5 mm toughened pane?
Yes. Toughened glass is made from about 4 mm up to 19 mm. A 5 mm pane is often used in smaller framed windows and cabinet doors. Larger or unframed openings usually need more thickness, so ask your glazier what suits the size and use.
