When choosing a thermal insulation film, the following key factors should be considered to ensure that the product is both practical and economical:

Warranty period: Choose a warranty period of at least 5 years, which is essential for long-term use and maintenance of insulation. For leased offices, you can choose the corresponding warranty products according to the service life; for home use, it is recommended to choose products with a 10-year warranty to avoid the trouble of frequent replacement.

Production process: The production process of the heat insulation film affects its durability and service life. The durability of the heat insulation film of the magnetron process and the vacuum aluminizing process is relatively good, and the clarity is slightly second, but the effect of this difference on the architectural glass is not obvious.

Internal or external: select the internal or external thermal insulation film according to the use scenario. Architectural glass can be considered external, while windows are usually internal. The outer film is suitable for scenes with good lighting and do not want too dark colors, while the inner film is suitable for occasions that require higher privacy protection.

Core function: high-quality insulation film should have heat insulation, UV protection, sufficient clarity, and possible additional functions such as explosion-proof ability, beautiful color and long-lasting insulation effect. Although the quality of products of well-known brands is guaranteed, the price may be higher. Therefore, in the case of limited budget, you can choose to use the brand for a similar experience.

Brand & Model: Choose the brand and model according to your budget. There are many brands of heat insulation film on the market, and the price range is wide. From below 1K to above 5K, different brands and models of heat insulation films are different in terms of heat insulation rate, explosion-proof ability, clarity, and UV blocking ability. When selecting, privacy and security needs should be considered, as well as the construction environment and the professionalism of the construction personnel.

Material and thickness: Material and thickness are also factors to consider when choosing a thermal insulation film. Different materials of heat insulation film in the heat insulation effect, explosion-proof performance and durability are different. The thicker the thickness, the higher the tear resistance and the better the explosion-proof effect.

Parameter comparison: the total solar energy barrier rate, light transmittance, UV blocking rate, explosion-proof performance and visible light reflectance are the parameters that need to be paid attention to when selecting the heat insulation film. The comprehensive performance of these parameters determines the overall performance and use effect of the thermal insulation film.

To sum up, when selecting heat insulation film, we should comprehensively consider factors such as warranty period, production process, selection of internal and external stickers, core functions, brand and model, material and thickness, and parameter comparison, so as to ensure that the products can meet the demand and be economical.
