As a benchmark material for high-end building energy conservation, it is widely used in passive houses, high-end office buildings, high-quality buildings in severe cold/hot regions, quiet-demand spaces and other scenarios. With outstanding energy-saving performance and stable quality, our products cover the national market. We sincerely look forward to cooperating with you to provide customized low-carbon glass solutions for various high-energy-saving standard construction projects.

Product Features and Applications

Dopin super energy-saving glass is a high-end energy-saving glass created by combining multiple panes (3-4 glass panes) and multi-cavity (2-3 insulating cavities) design. Its core advantage lies in multi-layer protection and extreme energy saving. The product integrates three core technologies: Low-e silver-based composite coating, high-purity argon gas filling and double high-efficiency sealing. The infrared blocking rate exceeds 90%, strongly blocking external high temperature in summer and firmly locking indoor heat in winter. The U-value is as low as 0.8 W/(㎡·K), far exceeding ordinary insulating glass and single-layer Low-e glass. Meanwhile, the multi-cavity structure greatly improves sound insulation performance, effectively blocking traffic, crowd and other noises, with a weighted sound reduction index ≥45 dB, balancing energy saving and quiet experience.

It is mainly applied in buildings with high energy-saving and quiet requirements:

For high-end home decoration: Suitable for villa floor-to-ceiling windows, high-quality residential doors and windows, sunrooms, especially for severe cold regions (north), hot regions (south) and noise-sensitive areas (near streets, airports).

In the commercial sector: Used in passive office buildings, high-end hotels, hospitals, libraries and laboratories, meeting the star standards of green buildings and quiet space needs.

For special scenarios: Adapts to buildings in coastal high-salt spray areas and ultra-low energy consumption buildings. With Grade C5 corrosion resistance and extreme energy-saving effect, it is suitable for harsh use environments.

It can be equipped with single-silver/double-silver/triple-silver Low-e coatings according to needs to meet different energy-saving grades and budget requirements.

Technical Parameters

Production Details

Ultra-strict quality control is implemented throughout the production process. High-quality float glass or ultra-clear glass is selected as the base glass. After water-free and dust-free cleaning and vacuum drying treatment, the processes of coating deposition and cavity combination are completed in sequence:

Low-e coating is deposited on the inner glass surface of the cavity by vacuum sputtering process, precisely controlling the coating thickness and uniformity.

The cavity combination adopts high-precision aluminum spacers (built-in desiccant), spliced according to the designed number of panes, and filled with high-purity argon gas (concentration ≥90%) to improve thermal and sound insulation performance.

Finally, double sealing process (butyl rubber + silicone rubber) is adopted to prevent air leakage and water ingress in the cavity, ensuring long-term sealing stability.

Glass edges are processed by precision grinding and chamfering, free of burrs and chipping, effectively avoiding breakage caused by stress concentration. The contact surface between spacers and glass fits closely, and the desiccant can absorb water vapor in the cavity for a long time to prevent fogging and condensation. The double sealing layer has excellent weather resistance and anti-aging properties, which can resist rainwater, salt spray and high-temperature exposure, avoiding sealing failure. All products are tempered to enhance mechanical properties, breaking into obtuse-angle particles to ensure safe use. Meanwhile, the coating is hidden inside the cavity to avoid external wear and corrosion, extending service life.

Instructions for Use and Precautions

Installation must be operated by professional personnel to ensure the frame load-bearing capacity meets the standard and the glass is under uniform stress. It is fixed with special structural adhesive and pressure strips. Knocking on glass edges and corners is prohibited to avoid stress breakage.

For daily cleaning, gently wipe with a soft cloth and neutral detergent. Steel wool and sharp objects are prohibited to scratch the glass surface, and acidic and alkaline reagents are avoided from contacting the glass and sealant.

Regularly check the sealing performance of insulating glass. If fogging, water ingress or condensation occurs, replace it in time to avoid the coating from being damp and peeling, affecting energy-saving performance.

Regularly check the status of the coating. If oxidation, peeling, fading, or fogging and water ingress of insulating glass occur, replace it in time to ensure energy-saving and use effects.

Avoid heavy object impact on the glass, especially high-rise curtain walls and outdoor glass, to prevent breakage and falling, and guard against impact by falling objects.

Frequently Asked Questions

Q: What is the core difference between the "Dopin" of Dopin super energy-saving glass and ordinary insulating glass?

A: The leakage rate is extremely low. Adopting double high-efficiency sealing process, the annual argon gas leakage rate is ≤1%, and the effective concentration can be maintained for more than 20 years under normal use. The product performance will not be affected by gas leakage, and the overall service life can reach more than 25 years.

Q: Will the filled argon gas leak slowly? Does it affect the service life?

A: It can be adapted in advance. Although the product is heavier than ordinary glass, the frame load-bearing can be optimized in combination with glass specifications during the architectural design stage. We will provide detailed weight parameters to assist in load-bearing adaptation without affecting building safety.

Q: Will the heavy weight of Dopin glass affect the building's load-bearing design?

A: No. Special salt spray-resistant sealant is selected, and the coating is hidden inside the cavity. The overall corrosion resistance grade of the product reaches Grade C5, which can resist coastal salt spray erosion, and there will be no oxidation, peeling or sealing failure after long-term use.
