What are the symptoms of inferior thermal insulation film?

There are many dangers associated with inferior architectural glass films. Some consumers may believe that there is no significant difference between cheap films and expensive ones. However, this is not the case.

Authentic glass films undergo professional testing, ensuring that the chemical components they contain pose no harm to the human body. They have passed relevant test reports. Consumers can request to see these test reports and other related procedures when making a purchase. Genuine glass films are exclusively produced abroad, accompanied by authentic and valid customs declarations and certificates of origin. These can be verified on the official website of the respective manufacturer. Inferior glass films not only result in wasted money but also pose health risks. In fact, inferior thermal insulation films exhibit several disadvantages, primarily in the following aspects:

(1) Shoddy and inferior high-transparency thermal insulation films offer poor thermal insulation performance. Customers can request on-site testing with relevant instruments to verify this.

(2) Inferior films have low clarity and lack an anti-scratch layer, making them less wear-resistant and unable to guarantee safety.

(3) Adhesives in inferior films may contain residual volatile formaldehyde, benzene, xylene, and other harmful substances, emitting a strong and pungent odor, thus seriously endangering human health. Relevant test reports can be requested to confirm this.

(4) UV blocking may not meet the standard in inferior films, and their colors can be dazzling, prone to fading, which is detrimental to appearance.

(5) The thermal insulation performance of inferior films is quite unstable, with the thermal insulation rate decreasing over time.
