The differences between installing window film and not installing window film
When it comes to car windows, installing window film offers heat and UV protection, keeping the interior cooler and safeguarding occupants, while also reducing glare and enhancing privacy for better driving visibility; without it, the car endures more heat, glare, and lacks privacy. For residential and commercial building windows, window film boosts energy efficiency by minimizing heat transfer, thus cutting heating and cooling costs, and protects interior furnishings from UV - induced fading. Additionally, it enhances the building's aesthetic appeal and provides privacy. In contrast, without window film, buildings consume more energy, interiors are prone to damage, and there is less privacy and visual charm.
What are the differences between different types of window film?
Type | Core Structure Characteristics | | Applicable Scenarios |
Dyed Film | Only dye layer + glue layer | 1-1.8mil | Low-end model, limited budget |
Metallic Film | Multilayer metal + polyester substrate | 2-3mil | In high temperature areas, pursue high insulation |
Nano Ceramic Film | Nano-ceramic particles + PET layer | 2-4mil | High-end models with signal penetration |
Privacy Film | Dark dye layer + one-way perspective technology | 2-3mil | Commercial/luxury cars, privacy oriented |
