Should Car Window Tints Be Applied on Both Inside and Outside?
2 Answers
Car window tints do not need to be applied on both the inside and outside. Below is an introduction to the functions of window tinting: Heat and Sun Protection: Window tints can effectively block a significant amount of heat generated by infrared rays, providing a comfortable temperature for both the driver and passengers. UV Protection: Medium and long waves of the sun's ultraviolet rays can penetrate thick glass. Applying heat-insulating film can block most UV rays, protecting the skin from damage and slowing down the aging of car interiors. Safety and Explosion Protection: The base layer of car window tints is made of polyester film, which has tear-resistant and penetration-proof functions. Combined with the adhesive layer of the film, the strength of the glass after tinting can prevent injuries to vehicle occupants caused by accidental glass breakage.
When I first bought my car, I had the same question, thinking that window films were applied on both the inside and outside. However, they are usually applied on the inner side of the windows. I watched the technicians at the 4S shop, and they applied the film entirely on the inner surface, explaining that this prevents rain and dust from damaging the film, thus extending its lifespan. If applied on the outside, exposure to wind and sunlight can cause the adhesive to fail, and the film is more prone to scratches and bubbles, which can impair visibility and waste money. A properly applied film blocks UV rays, protects the skin from sunburn, enhances privacy by preventing outsiders from peering in, and keeps the car noticeably cooler in summer, reducing the need for heavy air conditioning and saving on fuel costs. Remember to choose high-quality film and have it installed by professionals—don’t skimp on cost, as a poorly installed film can cause more trouble. Regular cleaning is also important; use a soft cloth to gently wipe the film and avoid chemical cleaners that could corrode it.
