Tempered glass
Tempered glass is heat-treated safety glass that breaks into small pieces instead of sharp shards.
Why it matters
It reduces injury risk and is required in many locations like near doors and showers.
Where people get this wrong
Tempered glass is about safety, not energy performance. It can still break. It just breaks safer.
Real-world example
A kid slips near a patio door and a toy hits the glass. Safety glass reduces the chance of a dangerous shard situation.
Where this hits your build
This comes up during selections and installation. Performance depends on the product and the install. A good window installed poorly still leaks.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
