Technical Parameters

Product Features and Applications

The core advantage of the Dopin Insulated Super Energy-saving Glass lies in its “multi-chamber protection + dual-direction extreme energy-saving” design. By combining 3-4 glass panes, we create 2-3 independent insulating cavities, enhanced by a silver-based Low-e coating and high-purity argon gas filling. With an infrared blocking rate over 90%, it effectively prevents heat from entering during summer and traps indoor heat during winter. The U-value is as low as 0.8 W/(㎡·K), outperforming ordinary double-glazed and single-layer Low-e glass. Furthermore, the multi-chamber structure and inert gas filling provide soundproofing with a weighted sound reduction of ≥45 dB, effectively blocking medium to high-frequency noise, creating both energy efficiency and tranquility. The coating is protected within the cavity, preventing wear and corrosion.

Applications focus on high-standard energy-saving and quiet environments:

Residential: Villa windows, luxury sunrooms, noise-sensitive residences, especially in northern cold and southern hot regions.

Commercial: Passive office buildings, high-end hotels, hospital wards, libraries, laboratories, meeting green building star ratings.

Special scenarios: Coastal, high-salinity environments, energy retrofitting for older buildings. The C5 corrosion-resistant feature and easy installation make it adaptable to various construction environments. Customizable with single-silver, double-silver, or triple-silver Low-e coatings to meet different energy standards and budget needs.

Production Details

The entire production process adheres to strict quality control standards. The base glass is made from high-quality float glass or ultra-clear glass, cleaned in a water-free and dust-free environment and vacuum-dried. In the core process, Low-e coatings are applied to the inner side of the cavity glass using a vacuum sputtering technique, with precise control over coating thickness and uniformity. The multi-chamber structure is formed with high-precision aluminum spacers (incorporating efficient desiccants), filled with high-purity argon gas (≥90% concentration) to improve thermal insulation and soundproofing performance. Dual sealing (butyl rubber + silicone rubber) ensures airtightness, preventing gas and moisture infiltration. Finally, the glass is tempered for enhanced mechanical properties. Automated production guarantees product consistency and quality.

The dual-seal layer offers excellent weather resistance and aging resistance, enduring temperature variations from -40°C to 80°C, preventing seal failure due to thermal expansion and contraction. The edges are polished and chamfered, eliminating burrs and reducing stress concentration, minimizing breakage risks. The desiccant inside the spacer efficiently absorbs moisture, preventing fogging and condensation. All products are tempered to safety standards, with broken glass presenting blunt edges to ensure safety. The coating and sealing structures work together to protect the glass, providing a lifespan of 25 years or more.

Structure and Design Explanation

The core structure of the Dopin Insulated Super Energy-saving Glass uses a three-glass two-cavity and four-glass three-cavity setup. Common specifications include:

3-glass 2-cavity (5+12A+5+12A+5): Basic model, U-value 1.2-1.5 W/(㎡·K), balanced cost-performance, suitable for general high-end energy-efficient buildings.

3-glass 2-cavity (6+12A+6+12A+6): Thicker version, U-value 1.0-1.2 W/(㎡·K), sound reduction ≥48 dB, suitable for cold/hot regions.

4-glass 3-cavity (5+12A+5+12A+5+12A+5): Premium version, U-value ≤0.8 W/(㎡·K), sound reduction ≥50 dB, suitable for passive houses, laboratories, etc. Can be combined with laminated glass for added energy-saving and blast-resistant properties.

The design supports custom transparency (50%-75%) and color options (light gray, light blue, clear), and non-standard sizes can be customized (up to 2440mm × 3660mm). Suitable for curtain walls, irregular doors, floor-to-ceiling windows, and skylights. Proper installation ensures uniform glass pressure, using specialized bearing frames and structural adhesives to avoid breakage due to stress imbalance or temperature variations. Do not disassemble the cavity to preserve the sealing structure.

Usage Instructions and Precautions

Installation: Must be performed by professionals, ensuring the frame can bear the weight and using specialized structural adhesives and spacers. Do not hit glass edges to avoid stress fractures.

Cleaning: Use soft cloth and neutral cleaners, avoid abrasive pads or sharp objects, and prevent acidic or alkaline chemicals from touching the sealant.

Regular Checks: Inspect cavity seals regularly. If fogging or moisture is detected, replace the glass to prevent damage to the coating.

Impact Protection: Avoid heavy impacts, especially in high-rise or floor-to-ceiling windows. Replace immediately if cracks appear.

Temperature Care: After exposure to high heat, avoid sudden cooling with cold water. Snow and ice should be removed in winter to prevent glass damage.

Do Not Disassemble: Do not dismantle the cavity or cut the glass to avoid compromising the seal and structure.

FAQs

Q: What is the key difference between Dopin Insulated Glass and regular insulated glass?

A: The core difference lies in the number of panes and cavities. Dopin glass uses 3-4 panes and 2-3 cavities filled with argon gas and dual seals, offering 2-3 times better thermal and soundproofing performance than standard double-glazed single-cavity glass.

Q: Will the argon gas leak over time? Will it affect the lifespan?

A: The leakage rate is minimal. Dual-seal technology ensures that the argon gas leakage rate is ≤1% per year, and it remains effective for up to 20 years, with over 80% concentration retained. The product lifespan is over 25 years.

Q: The glass is heavier than regular glass. Will it affect the building's load-bearing capacity?

A: This can be addressed during the design phase. Though heavier, the appropriate frame can be selected to handle the additional weight without affecting the building's safety.
