Product Description

Product Description

1.The high-temperature resistance of this product (220°C) enables secondary processing during the window manufacturing process, minimizing material waste to the greatest extent.

2.It has excellent corrosion resistance, weather resistance, high-temperature resistance and alkali resistance, which can extend the service life and effectively reduce the total cost of window ownership.

3.Compared to aluminum alloy windows, those incorporating Noise Reduction Thermal Barrier Strips demonstrate superior acoustic performance, making them suitable for a wider range of application scenarios.

4.Windows with thermal break strips deliver superior insulation performance, significantly reducing household electricity consumption during both summer and winter seasons.
