Do Sunroofs Need Heat Insulation Film?
1 Answers
Generally, car sunroofs do not require film application. This is because sunroof glass typically already has UV protection and heat insulation functions. Applying film again would not only result in a certain degree of resource waste but also affect the overall quality of the vehicle. For example, after applying film to the sunroof, the increased thickness of the glass may, if not installed properly, lead to difficulties in opening and closing the sunroof smoothly. Cases where car sunroofs may need film: During hot summers, if a car is parked outdoors for an extended period, the sunroof area, being a weak point in roof insulation, can contribute to an increase in interior temperature. If the decorative panel under the sunroof is opened, even more heat can enter the vehicle through the sunroof. Therefore, large panoramic sunroofs may consider film application depending on regional seasonal climates. However, not all panoramic sunroofs are suitable for film. If the sunroof is made of tinted heat-absorbing glass, dark-colored films should not be applied. Similarly, sunroofs with dotted black enamel are not suitable for film. Any modifications or decorations made to the vehicle should ideally be done after consulting professional installers. Maintenance of car sunroofs: Sunroof leakage, where water seeps into the car interior after rain, can occur due to two reasons. First, the sunroof drainage channels may be clogged, in which case regular cleaning of the sunroof tracks is necessary. Second, the sunroof sealing strip may not be sealing properly. The sunroof is sealed with rubber gaskets, and it's important to keep these gaskets free from dust during use. Sunroof noise is another common issue, often occurring when the sunroof hasn't been used for a long time. Upon opening, a squeaking noise may be heard, caused by accumulated dust and sand particles in the tracks and gaps. If not cleaned regularly, these can cause noise and, in severe cases, wear down sunroof components, leading to track deformation.
