What are black spots on car windshields for?
Imagine a summer day when your car is exposed to a blazing sun. While the center of the windshield heats up intensely, its edges remain relatively cool. This thermal variation could weaken the glue that fixes the glass to the bodywork. This is where those famous black spots, called frits, come into play.
These patterns create a gradual transition between the light and dark areas of the windshield, reducing temperature differences and thus protecting the glue from degradation. Without this trick, the risk of cracks or detachment would be much higher. A discreet innovation, but crucial for the durability and safety of your vehicle.
A well thought out touch of elegance
Beyond their protective role, the frits also have an aesthetic mission. They cleverly hide the glue edges, providing a clean and elegant finish to the windshield. This attention to detail does not stop there: they also reduce annoying reflections of the sun on the edges of the windshield, thus avoiding potentially dangerous glare for the driver.
In summary, these small, discreet patterns fulfill a dual role, both practical and aesthetic, which often goes unnoticed but contributes greatly to the visual comfort and harmony of automotive design.
A standard that guarantees safety
Did you know that modern windshields meet strict standards, such as European regulation R43? This ensures their ability to withstand impacts while protecting passengers in the event of an accident. These small black dots indirectly contribute to these safety standards, by reinforcing the overall durability of the windshield.
In addition, in France, the law requires windows to be in good condition. A damaged windshield can not only result in fines, but also the immobilization of your vehicle. Good maintenance, in accordance with these rules, is therefore essential.
