Frequently asked questions

These glass sheets are held together permanently by an interlayer such as polyvinyl butyral (PVB). Laminated glass is about two times stronger than standard float glass of the same thickness, with the advantage that in case of breakage, it generally holds together by breaking into a spider-web pattern.

Float glass: This is the most budget-friendly and has no natural tint. It is a single piece of glass that breaks into sharp shards when hit with force. Float glass can, however, undergo a lot of chemical processes to be strengthened. It can be used in single-pane and even double-pane windows once it's been enhanced.

The cost factor is a significant consideration, as it tends to be more expensive than standard glass options.

Annealed Glass -- This is the most commonly used glass type today and is used in most home windows. It is manufactured using the float method

Toughened is around 5 times stronger than laminated. It, therefore, needs to be hit a lot harder for the glass to break. When toughened is hit with enough force, it will break up into lots of small, blunt pieces rather than long sharp shards.
