Surviving Summerlin Summers: Ceramic Ultimate Plus Performance Data

Performance Published 2026-05-24 Polar Tint Summerlin

Summerlin summer surface temperatures inside parked vehicles regularly exceed 150°F. Dashboard and steering wheel surfaces hit 180°F+ on parked black-interior vehicles in direct sun. Ceramic Ultimate Plus changes that math materially.

What “98% IR rejection” actually means

Infrared radiation (IR) is the wavelength that creates HEAT inside a car. Visible light goes through windows and bounces off interior surfaces — it’s the IR component that gets absorbed and re-emitted as heat. Reject IR and you reject the heat source.

Polar Tint Ceramic Ultimate Plus is built to reject:

  • Infrared rejection (IR): up to 98% at darker VLTs
  • UV rejection: 99% at every VLT

Real-world comfort difference

Rejecting IR at the glass instead of letting it into the cabin means a noticeably cooler interior on a parked car and less strain on the AC system to get back to a comfortable temperature. The darker the VLT, the more of that heat load gets stopped before it ever reaches the dash and seats.

Nevada-legal VLTs

Nevada caps front side windows at 35% VLT. Polar Tint Summerlin installs Ceramic Ultimate Plus at 35% on front sides and any darkness on rear sides and the back window. The 35% IR rejection number is in the 80-85% range — still dramatically better than dyed film at any VLT.

Summer heat rejection in Summerlin, answered.

What does 98% IR rejection actually mean?
Infrared radiation (IR) is the wavelength that creates heat inside a car. Visible light passes through the glass and bounces off interior surfaces, but it’s the IR component that gets absorbed and re-emitted as heat. Reject the IR and you reject the heat source. Polar Tint Ceramic Ultimate Plus rejects up to 98% IR at darker VLTs.
How much cooler is a tinted car in a Summerlin summer?
Ceramic Ultimate Plus rejects IR heat at the glass before it reaches the cabin, so parked and driving interior temperatures run noticeably cooler than an untinted vehicle, and the AC doesn’t have to work as hard to catch back up.
Does ceramic tint block UV too, not just heat?
Yes. Ceramic Ultimate Plus rejects 99% of UV at every VLT. UV is the wavelength that fades interiors, so 99% UV rejection protects your dash, seats, and trim regardless of how dark you go.
Can I still get strong heat rejection on a Nevada-legal 35% front window?
Yes. Nevada caps front side windows at 35% VLT, and Polar Tint Summerlin installs Ceramic Ultimate Plus at 35% on the front sides with any darkness on the rear glass. Even at the legal 35% front, IR rejection lands in the 80–85% range — still dramatically better than dyed film at any VLT.
