How to choose Low-E glass protective film

When choosing a Low-E glass protective film, there are typically two options: transparent film and aluminum-coated film.

These two choices have different characteristics and suitable applications.

1. Transparent film: Transparent film is a colorless or slightly colored protective film, usually made of polyester. It has high light transmittance and can maintain the original transparency and appearance of the glass. Transparent film provides good protection, reducing UV transmission and improving thermal insulation performance without compromising the visual experience. Transparent film is suitable for scenarios where glass protection is needed without affecting the visual effect, such as windows, sunrooms, etc.

2. Aluminum-coated film: Aluminum-coated film is a protective film with a metallic coating. It has high reflectivity and thermal insulation properties, effectively blocking heat transfer and UV transmission. Aluminum-coated film can maintain indoor comfort in terms of temperature while reducing energy consumption and air conditioning load. However, the aluminum coating on the glass surface may create a metallic reflection, potentially affecting the visual effect and light transmission from both inside and outside. Therefore, aluminum-coated film is more suitable for scenarios where transparency is not a priority, such as office buildings, commercial buildings, etc.

The choice between transparent film and aluminum-coated film depends on specific needs and usage scenarios. If you want to maintain glass transparency and visual effects while improving thermal insulation performance, transparent film is a good choice. If you prioritize thermal insulation performance and energy efficiency without being overly concerned about visual effects, aluminum-coated film may be more suitable. It is recommended to select the appropriate Low-E glass protective film based on specific application requirements and personal preferences.
