Sierra Glass Fabrication is a major supplier of tempered glass.

• 5 times stronger than normal glass 
• Made by extreme heating and rapid cooling, making it harder than normal glass.
• Due to the fragility of tempered glass, it breaks into small oval stones. This eliminates the risk of sharp edges. Tempered glass is found in doors, windows, bathrooms, and shower doors.

Sierra Glass Fabrication currently uses the Glaston FC 500 tempering oven. We provide heat-treated materials that are up to ASTM codes.

• Minimum Size Tempered 7″ x 7″
• Diagonal 11″
• Rectangle is 4″ x 7″
• Maximum Size Tempered 96″ x 144″
