Choosing glass: the questions to ask

Window glass affects privacy, safety, heat, noise and appearance. Choose it for the size and position of the opening, and ask for the exact type and thickness in writing.

What you need to know.

A door at ground level, an upper-floor window and a bathroom pane need different checks. Ask about the glass type, thickness and fit with the frame. Toughened glass is heat-treated; laminated glass has bonded layers; double glazing has separated panes. Privacy glass changes how clearly people can see through it.

How to choose for your home.

Request a written glass specification and discuss any required engineering or safety assessment. Do not choose by thickness alone or assume a darker appearance guarantees better heat control.

Your practical checklist.

  • Identify impact-risk locations.
  • Specify privacy needs.
  • Review pane size and support.
  • Ask for the exact glass construction.

What to share with our team.

Send a photo of the window or door opening and the room around it. Write the approximate width and height in feet, inches or millimetres, and clearly mention the unit. Tell us what matters most: fresh air, privacy, mosquito mesh, easy cleaning or space saving.

The team will confirm the final size, suitable materials, price and installation work. If your project needs an engineer’s approval or special safety requirements, discuss these before placing the order.
