GREAT QUESTION — HEAT TEST REPORTS. Texas Tint Masters verifies all ceramic window tinting installations with personalized heat test reports we include — giving you the EXACT testing numbers on your actual glass. This is important because it is extremely difficult to determine a true ceramic window tint just by its visual appearance. A proper test requires infrared lamps, BTU & IR Meters and knowledge of operating the equipment. At Texas Tint Masters, you can rest assured you are getting a proper ceramic tinting installation.
