What is Tempered Glass?
Tempered glass is a safety glass that has undergone a controlled thermal treatment (tempering process) to increase its strength compared to normal or annealed glass. This process consists of uniformly heating the glass to a temperature of approximately 650°C or 700°C and then rapidly cooling it with jets of cold air on the surface.
This rapid cooling subjects the outer surfaces to compressive stresses, while the interior of the glass remains under tensile stresses. This stress distribution gives it its superior mechanical properties:
- Core in tension: Maintains the internal cohesion of the material.
- Surface in compression: Prevents the propagation of external micro-cracks.
- Safe fragmentation: In case of breakage, the glass disintegrates into thousands of small, granular fragments with blunt edges, drastically reducing the risk of serious injuries.
When is it needed?
A maintenance or plant manager should consider installing tempered glass systems when the following operational scenarios occur:
- Workspace reconfiguration: Need to define supervision offices within industrial warehouses without losing visibility to the production line.
- Compliance with safety regulations: High-traffic areas where common annealed glass poses an imminent risk of workplace accidents.
- Acoustic and thermal control requirements: Need to isolate administrative areas, laboratories, or meeting rooms from the noise and temperatures of the production plant.
- Areas prone to mechanical vibrations: Spaces near presses, stamping machines, or constant forklift traffic that require high structural resistance glass.
- Areas of high hygiene and contaminant control: Laboratories, industrial cafeterias, or packaging areas that require smooth, non-porous, and easy-to-sanitize surfaces.
Problems it solves
The installation of industrial-grade tempered glass systems solves critical safety and efficiency problems:
- Risks of workplace accidents: Eliminates the danger of severe cuts caused by the breakage of common glass that generates sharp and piercing splinters.
- Loss of operational visibility: Allows supervisors to maintain direct visual contact with assembly lines from elevated offices or control booths.
- Deterioration due to corrosion and humidity: Unlike drywall or wood panel walls, tempered glass resists humidity, oils, and chemical cleaning agents without degrading.
- Non-conformities in audits: Resolves observations from STPS, COFEPRIS, or international guidelines (such as SQF or BRC) related to the physical safety of facilities.
Benefits for your plant
- Certified passive safety: Minimizes the impact of accidents and reduces liability insurance premiums thanks to the safe behavior of the glass in case of breakage.
- Natural light optimization: Allows natural light to pass into the plant interior, reducing electricity consumption for artificial lighting.
- Extreme durability: Resists incidental mechanical impacts from tools or light equipment that would destroy common glass.
- Acoustic insulation: In combination with airtight hardware and perimeter seals, it significantly reduces decibel (dB) levels from the manufacturing area to the offices.
Applications and industries that use it
SINE México designs and installs tempered glass solutions for various industrial sectors in Coahuila and the northeastern part of the country:
- Automotive and Auto Parts Industry: Quality control booths, production floor supervision offices, and machinery protection barriers.

Materials and technologies
At SINE México, we do not compromise on the quality of components to ensure long-term structural stability:
- Certified Quality Glass: We use glass processed under strict thermal control standards, ensuring homogeneous tempering free of excessive optical distortions.
- Stainless Steel Hardware (AISI 304 and 316): Prestigious brands such as Bruken, Herralum, and Dormakaba, which guarantee continuous opening cycles without metal fatigue.
- High-Performance Sealants: We use neutral architectural-grade silicones (such as Dow Corning / Dowsil or SikaSil) with excellent adhesion, UV resistance, and anti-fungal properties for wet areas.
Applicable Regulations and Standards
Our installations and tempered glass specifications comply with the following regulatory frameworks:
- NOM-001-STPS-2008: Buildings, premises, facilities, and areas in workplaces - Safety conditions (specifically regarding the resistance and signaling of glass in high-traffic areas).
- ANSI Z97.1 (EUA): American standard for safety glazing materials used in buildings.
- ASTM C1048: Standard specification for heat-treated flat glass (tempered and heat-strengthened class).
Our work process (SINE)
- Survey and Technical Diagnosis: We visit your plant in Torreón, Saltillo, or Piedras Negras to take precise measurements with laser equipment and evaluate the structural conditions for fastening.
- Engineering and Design: We calculate the appropriate glass thicknesses and hardware type based on wind loads, vibrations, and area traffic.
- Fabrication and Tempering: All cuts, hardware cutouts, and edge polishing are performed before the pieces enter the tempering oven.
- Professional Installation: Our qualified technical personnel carry out the assembly using appropriate safety equipment, ensuring perfect alignment and plumb of the panels.
- Sealing and Adjustment: Application of perimeter sealants and fine adjustment of hardware, hydraulic hinges, and locks.
- Functionality Tests and Delivery: Verification of door clearance, smooth opening, and final cleanup upon project completion.
Common errors when hiring / installing
- Taking incorrect measurements before tempering: Attempting to adjust the glass on-site by grinding leads to the total loss of the piece.
- Use of inadequate hardware: Using low-quality alloy hardware (such as zamak) in humid or corrosive industrial environments causes mechanical failures within a few months.
- Lack of perimeter clearances: Tempered glass must not come into direct contact with metals or concrete. The absence of neoprene or silicone gaskets causes breakage due to expansion stresses.
- Ignoring wind and vibration loads: Installing glass that is too thin in very wide openings generates dangerous flexing due to air currents or machinery vibrations.
Factors determining cost
The cost of an industrial tempered glass project is calculated based on design and depends on:
- Glass thickness: Thicknesses of 12 mm or laminated systems have a higher cost than the standard 10 mm.
- Complexity of cutouts and perforations: A greater number of holes for locks, handles, or special connectors increases processing cost.
- Type and finish of hardware: AISI 316 stainless steel hardware for highly corrosive environments costs more than anodized aluminum.
- Logistics and installation maneuvers: Installation height, need for scaffolding, lifting platforms, or operations during special hours (nighttime or weekends).

Frequently Asked Questions
What thickness of tempered glass is recommended for office and industrial building divisions?
For standard interior partitions and divisions, 10 mm thick glass is used. In applications exposed to heavy traffic, wind pressure, or heights exceeding 2.70 meters, 12 mm tempered glass or laminated-tempered systems with high-strength structural fastening hardware are prescribed.
Can tempered glass be cut or drilled on-site during installation?
No, tempered glass cannot be cut, drilled, or mechanically modified once it has undergone the thermal tempering process. Any attempt to alter it will release internal stresses and cause immediate breakage of the glass. All perforations, cutouts, and edge polishes are done in the workshop before tempering.
What type of hardware does SINE México use to ensure durability in industrial environments?
We exclusively use AISI 304 and AISI 316 stainless steel hardware, as well as high-strength anodized aluminum. These materials ensure excellent resistance to corrosion, wear from continuous use, and common chemical cleaning agents in industrial plants.
