Frequently asked questions

  • What is an appropriate glass thickness for windows?

    Our standard glass panes for windows are four millimetres thick. However, we can supply glass in thicknesses up to 19 millimetres (for toughened glass) or 60 millimetres (for laminated glass).


    The thickness you need depends on the specifications of your glazing unit and the type of glass you plan to use. Please get in touch and our experts will do their best to help.

  • What is the best glass for double-glazing units?

    Four-millimetre toughened glass is now standard for most residential applications. However, you may need to specify another type of glass for windows that will be used in high-risk or public-facing areas. For instance, we can supply fire-rated glass that's suitable for use in a similarly fire-resistant framing system.
