Do darker car window tints have higher infrared blocking rates?

Most of heat emitted by sunshine is from infrared rays with wavelengths ranging from 760 to 2500 nanometers. We can feel the "invisible" heat from sunlight directly, and because it contains the most energy, the heat is also high. As a result, the higher the infrared blocking rate of vehicle window tint, the better the heat insulation effect.

Many customers often inquire whether the darker the tint, the greater the infrared blocking rate. Not all color have a higher infrared blocking rate. Some tints are made darker by adding color pigment, but pigmented colors cannot effectively filter infrared rays and will only block visible light. Even if the tint is very light in color, it can allow visible light to enter the vehicle's interior while efficiently keeping infrared rays outside the car in current advanced film-making process.

So therefore, the darker the tint, the higher the infrared blocking rate, is not a factor that can be used to determine whether the tint is high or low infrared blocking.

So, how do you calculate the tint's infrared blocking rate? You must use a special testing tool to test it at this time. It is critical to select a device that is suitable for your tint. At the moment, the 940nm and 1400nm bands are commonly used on the market to evaluate the infrared blocking rate. The spectral curve of the tint is defined by the manufacturing process. In general, absorbing films (IR high-insulation films) add 940nm absorbers, resulting in a higher blocking rate at 940nm. At 1400nm, metal magnetron sputtering films have a higher infrared blocking rate. This type of simple tint testing tools can be used as an extra tool for reference to choose a right car tint
