Tempered Glass

Tempered glass is a safety glass product manufactured through controlled heating and rapid cooling. Compared with ordinary annealed glass, tempered glass provides higher mechanical strength, better thermal resistance and safer breakage behavior. When broken, it tends to fragment into small granular pieces rather than sharp large shards, making it suitable for architectural, commercial and interior applications.

Barrett Limited supplies custom tempered glass for doors, windows, facades, partitions, shower enclosures, railings, furniture and other building projects. We support project-based dimensions, glass thickness options, edge processing, drilling, notching, polishing and export packing according to buyer requirements.

What Is Tempered Glass?

Tempered glass, also known as toughened glass, is produced by heating glass to a high temperature and then rapidly cooling the surface. This process forms compressive stress on the glass surface and tensile stress inside the glass, improving strength, impact resistance and thermal shock resistance.

Because of its safety performance, tempered glass is widely used in areas where strength, durability and user protection are important. It is commonly specified for commercial buildings, residential projects, hotels, shopping centers, offices, schools and public facilities.

Main Advantages of Tempered Glass

Tempered glass is selected for architectural and commercial projects because it offers a practical balance of safety, durability and design flexibility.

• Higher strength than ordinary annealed glass
• Improved resistance to impact and bending stress
• Better thermal shock resistance
• Safer breakage pattern for building and interior use
• Suitable for doors, windows, partitions, railings and facade systems
• Can be combined with laminated glass or insulated glass units
• Available with custom cutting, edging, drilling and notching before tempering

Common Applications

Tempered glass can be used in a wide range of building and interior applications. It is suitable for both residential and commercial projects where strength, safety and clean appearance are required.

• Glass doors and entrance systems
• Window glass and storefront glass
• Shower enclosures and bathroom partitions
• Glass railings, balustrades and handrails
• Interior partitions and office glass walls
• Table tops, shelves and furniture glass
• Facade and curtain wall glass
• Skylight, canopy and roof glass systems

For projects requiring additional post-breakage retention, tempered glass can also be laminated to form tempered laminated glass.

Available Processing Options

Barrett Limited can supply tempered glass with different processing options according to project drawings and application requirements. All cutting, drilling, notching and edge work must be completed before the tempering process, because tempered glass cannot be cut or drilled after heat treatment.

• Flat or custom size tempered glass
• Clear, low iron, tinted, frosted or patterned base glass
• Flat polished edge, pencil edge, bevel edge or arris edge
• Holes, notches and cut-outs before tempering
• Screen printing or decorative treatment when required
• Tempered laminated glass combination
• Tempered insulated glass unit combination

Tempered Glass Specifications

Tempered Glass Processing Overview

The production of tempered glass starts with glass selection, cutting and edge processing. Any holes, notches or special shapes should be finished before tempering. After washing and inspection, the glass is heated and rapidly cooled to achieve the required safety performance.

Quality Control and Packing

For export projects, dimensional accuracy, edge quality and safe packing are important. Barrett Limited can support inspection, project labeling, protective packaging and wooden crate packing to reduce transportation risk.

Before shipment, tempered glass can be checked based on size tolerance, visual quality, edge processing, hole position, surface condition and project packing requirements.

Related Products

Depending on project requirements, tempered glass can be combined with or compared with other architectural glass products.

• Laminated Glass for enhanced safety and post-breakage retention
• Insulated Glass for thermal and acoustic performance
• Low Iron Glass for high transparency and premium appearance
• Frosted Glass for privacy and decorative applications
• Bullet-Proof Glass for security-related projects

Frequently Asked Questions

What is tempered glass used for?

Tempered glass is commonly used for doors, windows, facades, railings, shower enclosures, partitions, furniture and other architectural glass applications where strength and safety are required.

Can tempered glass be cut after tempering?

No. Cutting, drilling, edging and notching should be completed before the tempering process. Once the glass is tempered, further cutting or drilling may cause breakage.

Can tempered glass be laminated?

Yes. Tempered glass can be combined with interlayer materials to produce tempered laminated glass for improved safety, security and structural performance.

What information is needed for a tempered glass quotation?
