Main Advantages of Injected Sealant Aluminum Alloy Doors and Windows

Injected sealant aluminum alloy doors and windows offer a wide range of benefits that make them an excellent choice for modern construction. Below is an expanded version outlining their key advantages:

1. Excellent Thermal Insulation and Energy Efficiency:  

Aluminum profiles filled with polyurethane thermal insulation injection sealant have a K-value of 0.12 W/MK, offering excellent thermal insulation performance. The aluminum profile, completely sealed with no seams, provides optimal insulation for the doors and windows of a building, helping to maintain indoor temperatures and reduce energy consumption. This results in significant energy savings, especially in extreme weather conditions, making these windows a preferred choice for energy-efficient buildings.

2. Superior Mechanical Properties:  

The polyurethane thermal insulation injection sealant used in aluminum profiles exhibits strong mechanical properties, including excellent tensile strength, resistance to fracture, and good elongation. These profiles also offer high impact resistance, wear resistance, cut resistance, and crack resistance, making them durable and long-lasting under various operating conditions.

3. Flexible and Attractive Design:  

The polyurethane thermal insulation injection sealant technology is simple and does not impose any special requirements on the aluminum profile. The cross-section is delicate, offering greater flexibility in design. Aluminum doors and windows treated with this insulation method retain their original rich colors, high strength, and refined aesthetics, while significantly improving their insulation and energy-saving properties. The treated aluminum profiles can be used for various window styles such as sliding, lifting, inward/outward casement, tilting, and even custom curved windows, making them versatile for both residential and commercial applications, including curtain walls.

4. Higher Production Efficiency:  

The production process is straightforward, and the polyurethane injection sealant technology completes the processes of pouring, curing, and thermal break simultaneously, making it suitable for large-scale, continuous production. This helps in increasing overall efficiency and reducing production costs.

5. Reduction in Aluminum Usage:  

When achieving the same insulation effect, aluminum profiles produced with polyurethane thermal insulation sealant can save over 10% of aluminum compared to other insulation technologies. Moreover, due to the seamless and continuous production process, this method significantly reduces aluminum waste, with only 1-2% material loss.

6. Reduction of Condensation on Glass:  

Condensation on glass can affect the quality of a building. By using polyurethane thermal insulation injection, this phenomenon is significantly reduced, helping to maintain a better indoor environment and improving the overall durability of the building.

7. UV Resistance:  

Even under prolonged exposure to ultraviolet (UV) radiation, the mechanical properties of the injected sealant and aluminum profiles remain unchanged, ensuring long-term safety and performance stability. This makes these windows ideal for areas with high sun exposure.

8. Suitable for Humid and Rainy Environments:  

The polyurethane thermal insulation sealant is a non-water-absorbing polymer material. Even after prolonged exposure to water, its performance does not degrade, making it suitable for use in rainy and humid climates.

9. Good Seismic Performance:  

The thermal insulation sealant forms an excellent elastic mechanical bond with the aluminum profile. With a fracture elongation rate greater than 20%, it ensures that aluminum doors, windows, and curtain walls remain intact during seismic activity.

10. Performance in Extreme Temperatures:  

Injected polyurethane thermal insulation maintains its mechanical properties in extreme temperatures ranging from -41°C to 50°C, ensuring durability and functionality in both high and low-temperature environments.

11. Environmentally Friendly:  

Polyurethane thermal insulation sealant is a green, environmentally friendly product. It contains no volatile organic compounds (VOCs) or harmful heavy metals, posing no risk to human health or the environment, making it an ideal choice for sustainable building practices.
