As QinHuangDao LianYiDing Glass Co., Ltd., a dedicated manufacturer since 2003 with over 5,000 square meters of production facilities and a workforce of 201-300 skilled professionals, we specialize in producing high-performance glass solutions for demanding applications. Our 4mm Tempered Greenhouse Glass Panels with UV Protection are engineered specifically for the rigorous needs of modern horticulture. Leveraging our extensive experience in serving global markets across North America, South America, Europe, and Asia, we deliver glass that combines exceptional durability, safety, and light transmission efficiency essential for optimal plant growth. This product represents our commitment to quality, backed by ISO9001 and ISO14000 certifications, ensuring reliability you can trust for your greenhouse projects.
Product Features & Technical Specifications:
Designed to withstand the unique challenges of greenhouse environments, our panels offer:
- Enhanced Safety: Fully tempered glass undergoes a controlled thermal process, increasing its strength 4-5 times compared to annealed glass. In the rare event of breakage, it shatters into small, granular pieces with dull edges, significantly reducing the risk of injury to personnel or damage to plants.
- Superior UV Protection: A specialized coating is applied to filter out harmful ultraviolet (UV) rays while maximizing beneficial light transmission. This protects sensitive plants from UV damage and helps regulate internal greenhouse temperatures more effectively.
- Optimal Light Transmission: High clarity glass ensures maximum photosynthetic active radiation (PAR) reaches your crops, promoting healthy growth and higher yields. The 4mm thickness provides an excellent balance between light transmission and structural integrity.
- Thermal Stability & Durability: Tempering enhances resistance to thermal stress, making the panels highly suitable for environments with significant temperature fluctuations between day and night. They exhibit excellent resistance to wind, snow loads, and minor impacts common in agricultural settings.
- Low Maintenance & Longevity: The smooth surface is easy to clean and resists dirt accumulation better than some plastic alternatives. Tempered glass is highly resistant to scratching, hazing, and chemical degradation from fertilizers or cleaning agents, ensuring long-term clarity and performance.

Frequently Asked Questions (FAQ):
Q1: Why choose 4mm thickness for a greenhouse?
A1: 4mm offers an optimal balance between strength, light transmission, weight, and cost. It provides sufficient structural integrity for most greenhouse frames while allowing excellent light penetration crucial for plant growth, making it a popular and practical choice.
Q2: How does the UV protection coating work, and does it wear off?
A2: The coating is typically a durable, metal oxide layer applied during manufacturing. It selectively filters harmful UV wavelengths. This coating is fused to the glass surface and is highly resistant to weathering, cleaning, and abrasion, ensuring long-lasting protection.
Q3: Is this glass safe for overhead use in greenhouses?
A3: Yes, absolutely. The tempering process makes it safety glass. If broken, it fragments into small, relatively harmless granules, minimizing the risk of injury from falling shards, which is essential for overhead glazing.
Q4: Can I get custom sizes and shapes?
A4: Yes, customization is a core strength. We can produce panels to your exact dimensions and specifications. Complex shapes like triangles or trapezoids are also possible, though minimum order quantities may apply. Please provide your detailed requirements.
Q5: How does tempered glass compare to polycarbonate for greenhouses?
A5: While polycarbonate is lighter and less prone to shattering, tempered glass offers superior clarity (light transmission remains constant over time), higher scratch resistance, better UV stability (won't yellow), greater longevity, and is often more resistant to certain chemicals. The choice depends on budget, specific structural needs, and performance priorities.
Q6: What certifications can you provide for this product?
A6: Our manufacturing processes are certified to ISO9001 (Quality Management) and ISO14000 (Environmental Management). We can provide material certifications and test reports (e.g., for fragmentation, surface compression) upon request. Product-specific certifications depend on the exact specification.
Q7: How should I clean and maintain these glass panels?
A7: Use mild soapy water and a soft cloth, sponge, or squeegee. Avoid abrasive cleaners or pads that could scratch the surface. Rinse thoroughly. Regular cleaning prevents mineral deposits and maintains optimal light transmission.
Q8: Do you offer any treatments to reduce condensation (anti-fog)?
A8: While the standard panel does not include anti-fog coating, this can be available as a special option. Please inquire if hydrophilic coatings to minimize condensation drip are required for your project.
