How to choose the right glass
A guide to glass types and when you use them
Glass is not just glass. The choice of type determines both safety, energy and durability, and it is a core competence to be able to recommend the right one for the job. Here are the types you most often work with and what each can do.
§Common float glass
Float glass is standard glass. It is clear and flat but breaks into sharp dangerous shards. Therefore it is used where there are no special requirements for safety or energy — and often as raw glass which is later processed into other types.
§Safety glass
- 01Tempered glass: stronger and breaks into small less dangerous pieces
- 02Laminated glass: a film holds the shards together if it breaks
- 03Used where people can collide with the glass or fall against it
§Energy windows
Modern windows are built from multiple layers of glass with gas in between and an invisible coating that retains heat. They are heavier than old-fashioned windows but save energy and improve comfort. When you replace an old window it is often an energy window that goes up.
§Specialty glass
Beyond standard types there are mirror glass patterned glass fire glass and soundproof glass for special purposes. Knowing their properties — and their limitations — is what makes you a glazier customers can consult.
§Ask before you choose
Always ask questions about use, requirements, and placement before deciding on glass type: Where is the window? Can someone fall against it? Are there energy requirements? The answer determines the choice — and keeps you on the right side of the regulations.
