Zero T Sheet Features: This is a smooth sheet with no glue on the sheet, but it is a self adsorption type transparent heat shielding sheet that adheres to the glass. No-glue sheets are easy to drain and deflate and can be reapplied multiple times. Easy to remove from the edge of the sheet when you want to remove it. The transparency of the glass is cut off by about 99% of UV rays, and the temperature rises down to the window by about 5-10℃ after installation. Please use in accordance with road traffic laws and safety standards. Please use with glass other than glass on the windshield, driver and passenger sides. Sheet Size: W 11.8 x 16.5 inches (30 x 42 cm) (equivalent to 1 sheet of rear glass). When applying the sheet, please peel off the release paper (transparent film) and stick it with a weak blue Zero sheet (soft PVC sheet).
