When it comes to keeping your car comfortable and protected from the heat of the sun, understanding where that heat comes from is key. Many people think of sunlight as a single, unified force, but in reality, solar energy is divided into three primary components: UV rays, visible light, and infrared radiation. Each source contributes differently to the overall heat inside your vehicle, and knowing how to combat them can make a big difference in your driving experience.

Let’s take a closer look at each of these heat sources and how window tinting technology from XPEL PRIME XR and XR Plus can help reduce their effects, providing you with a cooler, safer, and more enjoyable ride.

The Three Sources of Heat from the Sun

  • Ultraviolet (UV) Rays – 3%
  • Although they only make up 3% of solar energy, UV rays are incredibly damaging. They can cause skin aging, sunburn, and even increase the risk of skin cancer. UV rays are also responsible for fading and deteriorating the interior surfaces of your vehicle, like the seats, dashboard, and other materials.
  • Visible Light – 44%
  • Visible light comprises a larger portion of the sun’s energy, around 44%. This is the light that we see and that allows us to perceive colors. Although it’s essential for vision, it also contributes to the heat you feel in your car. The more visible light that enters your vehicle, the warmer it gets.
  • Infrared (IR) Radiation – 53%
  • Infrared radiation accounts for the largest portion, around 53%, of solar energy. It’s a major contributor to the heat build-up inside your car. Infrared rays are invisible, but we can feel their heat. When infrared energy enters your vehicle, it heats up the interior quickly, making it uncomfortable for you and your passengers.

How XPEL PRIME XR and XR Plus Protect Against Solar Heat

At Blue Ocean Auto Spa, we offer high-quality window tinting solutions using XPEL PRIME XR and XR Plus films. These advanced ceramic tints are designed to block a significant portion of UV rays, visible light, and infrared radiation, making your car’s interior a much more comfortable place to be. Here’s how each of these products works to keep you cooler and more protected:

  1. UV Ray Protection
  • Both XPEL PRIME XR and XR Plus tints block up to 99% of harmful UV rays, giving you and your passengers an added layer of protection against sun damage. This feature also helps preserve the quality and color of your car’s interior.
  1. Visible Light Rejection
  • XPEL tints are designed to reduce visible light transmission, which means less sunlight enters your car. By doing so, the tint minimizes glare, making it easier for you to see the road, and helps reduce the amount of heat caused by visible light.
  1. Infrared Radiation Rejection
  • Infrared radiation is the biggest contributor to the heat in your car. PRIME XR and XR Plus films are designed with advanced technology to block up to 98% of IR radiation, significantly reducing the amount of heat inside your vehicle. This high-performance rejection helps keep the car interior much cooler, even on the hottest days.

Some vehicles arrive with a purpose already built into their design. The 2026 RAM 1500 RHO is one of them. With its aggressive stance, wide fender flares, sculpted hood, and unmistakable presence, the RHO blends off-road capability with a level of refinement that makes it just as comfortable in a driveway as it is on a backcountry trail. Finished in a deep metallic gray that shifts character under different lighting conditions, this particular truck deserved protection from day one. The owner had a clear goal. As a brand-new vehicle, the priority was preserving both the exterior and interior while reducing the effects of the Texas sun and the intense summer heat that can quickly make a cabin uncomfortable. At Blue Ocean Auto Spa in Cedar Park, the focus was on creating a protection package that would help maintain the truck's appearance and comfort for years to come. Protecting a New Finish Before the Miles Begin New vehicles often look flawless at first glance, but under proper lighting, even fresh paint can reveal minor imperfections from transportation, dealership handling, or factory finishing processes. Before any protective products were applied, the RHO underwent a thorough decontamination wash and paint preparation process. The metallic gray finish already carried impressive depth, but careful refinement helped maximize gloss and clarity across the large body panels. One of the defining characteristics of the RAM 1500 RHO is its size. The expansive hood, broad doors, and muscular rear quarters create a tremendous amount of painted surface area. When properly prepared, those surfaces become a canvas for reflections, allowing the metallic flake and color richness to stand out. Under the shop lighting, the truck's finish displayed sharp reflections and exceptional uniformity, particularly across the hood where the distinctive performance scoop and vent details create dramatic visual contrast against the surrounding paintwork.
