What aspects should be considered when selecting heat insulation film for buildings?

 Firstly, pay attention to the smell of the building's heat insulation film. Poor-quality heat insulation films often emit a strong, pungent odor, especially during installation, which can irritate the respiratory system. In contrast, high-quality heat insulation films should be odorless and devoid of impurities after installation.

Secondly, assess the tactile qualities of the heat insulation film. Inferior heat insulation films typically employ ordinary polyester films as their base material, lacking elasticity, toughness, and a tactile feel. They are prone to wrinkling and fail to meet the fundamental safety and explosion-proof requirements expected of building heat insulation films.

Thirdly, examine the coloration of the heat insulation film. Low-quality heat insulation films primarily rely on dyeing processes, akin to fabric dyeing, making them susceptible to discoloration and blurring over time, often tending towards brown hues. In contrast, premium heat insulation films are crafted using magnetron sputtering technology, which adheres rare and valuable space metals such as gold, silver, nickel, and titanium using a robust magnetic field. This process ensures uniform coloration, a natural space-metal aesthetic, and exceptional transparency.

Fourthly, consider the clarity of the heat insulation film. The clarity of a building's heat insulation film is contingent upon both the base material and the manufacturing process. Only films produced using state-of-the-art magnetron sputtering technology can guarantee exceptional clarity. This technology involves adsorbing rare metals onto the film's surface without the use of pigments or heat-absorbing agents, resulting in optimal clarity. Many subpar heat insulation films may exhibit a wavy pattern when viewed from the outside post-installation, causing obscured visibility and compromising the appreciation of outdoor scenery. This also poses safety concerns.
