Custom Windows of Any Shape

Tempered Glass

Tempered Glass is often used in bathrooms for safety reasons. The panels are heated and then cooled rapidly in a controlled environment, making the glass several times stronger than regular glass.

Tempered glass in a bathroom

Tempered Glass is ideal for use over bathtubs and in showers where if glass were to shatter, it will break into small pieces so as not to harm any occupants. Tempered glass is used in cars for the same reason.
