    Enhanced Strength & Professional Standards

    LYD GLASS only uses A-grade float glass to produce tempered glass, which will reduce the self-explosion rate of tempered glass. The edge of the glass is treated to avoid scratching the personnel.

    Tempered glass will be packed in strong wooden boxes and our tempered glass complies with American (CAN CGSB 12.1-2022, ANSI Z97.1-2015(R2020) and CPSC 16 CFR 1201-2024) and European standards (CE EN-12150-2:2004).

    Superior Safety

    Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments. When broken, it shatters into small granular chunks instead of splintering into jagged shards, making it safer for use in various applications.

    Thermal Stability

    Tempered glass exhibits remarkable thermal stability, capable of withstanding temperature fluctuations ranging from 250 to 320°C. In contrast, ordinary annealed glass can only tolerate temperature changes between 20 and 100°C.

    Production Process & Technical Detail

    1
    Glass Preparation & Cutting: Large sheets of annealed (float) glass are cut to the exact required dimensions using automated machines.
    2
    Edging: All edges are ground (flat, pencil, or beveled) to remove sharp edges and micro-cracks, preventing breakage during tempering.
    3
    Washing: Thorough cleaning with de-ionized water and brushes to remove dust, debris, or oils.
    4
    Heating & Quenching: Glass is heated to 620°C - 700°C in a furnace, then rapidly cooled by high-pressure air blasts to create compressive and tensile stress.

    4mm Toughened Glass for Greenhouses

    4mm toughened glass is a popular choice for greenhouse and garden house glazing. Its increased thickness provides enhanced strength and durability, making it suitable for structural safety and long-term performance.

    Key Advantages

    • Enhanced Strength: Resistance to wind loads, hail, and impacts.
    • Insulation: Better thermal regulation for plant growth.
    • Light Transmission: Ensures optimal visible light penetration.
    • Durability: Resistant to UV exposure and weather elements.

    Applications

    Aluminum Greenhouses
    Garden Houses
    Shed Houses
    PVC Windows & Doors
    Oven & Microwave Doors
    Partition Walls

    Frequently Asked Questions

    What makes tempered glass safer than regular glass?
    Tempered glass is designed to shatter into small, blunt, pebble-like pieces when broken. This significantly reduces the risk of serious injury compared to the large, sharp shards produced by regular annealed glass.
    Can tempered glass be cut or drilled after it has been processed?
    No. All cutting, edging, and drilling must be completed before the tempering process. Any attempt to cut or drill the glass after tempering will cause it to shatter completely.
    What is the thermal resistance of LYD tempered glass?
    Our tempered glass can withstand temperature fluctuations ranging from 250°C to 320°C, making it ideal for environments with high heat or rapid temperature changes, such as oven doors or outdoor greenhouses.
    Why is 4mm thickness recommended for greenhouses?
    The 4mm thickness offers a perfect balance of weight and strength. it provides superior resistance to environmental challenges like hail, heavy wind, and accidental impacts while maintaining excellent light transmission for plants.
    What international standards does your glass meet?
    Our glass complies with major global standards including European CE EN-12150-2:2004, American ANSI Z97.1-2015, and CPSC 16 CFR 1201-2024, ensuring top-tier safety and quality.
    How is the glass protected during shipping?
    We pack our tempered glass in strong, reinforced wooden boxes to ensure structural integrity and prevent damage during international transit.
