Where Should Car Explosion-proof Film Be Applied?
3 Answers
Car explosion-proof film should be applied to the inner side of the car glass to prevent damage from the external environment. If applied to the outer side, the use of wipers may cause scratches, affecting its effectiveness. The explosion-proof film consists of a safety base layer, heat insulation layer, colored coating, UV absorption layer, and transparent adhesive layer. The functions of explosion-proof film include reflecting and blocking infrared rays and heat-generating wavelengths, providing heat and UV insulation; reducing glaring light, offering one-way visibility, and automatically adjusting interior lighting; preventing glass from shattering and scattering; protecting the film surface from scratches to maintain the car's appearance; and enhancing the strength and rigidity of car glass. Steps for applying explosion-proof film: Protect the car interior; cut the film according to the window size; clean the front windshield; use a heat gun to shape the film; and perform fine trimming after shaping.
I always apply explosion-proof film on the inner side of car window glass, especially on side windows and rear windshield surfaces. The main purpose is to enhance the glass's impact resistance and prevent shards from scattering during accidents to protect passengers. My experience shows that the film must cover the entire glass surface without gaps. While the front windshield can be filmed, it's essential to choose certified products with high light transmittance to comply with regulations, otherwise fines may apply. Installation must be done by professional shops - they first clean the glass to remove grease and dust, then carefully apply the film using tools to avoid bubbles and wrinkles. Besides safety improvement, properly installed films effectively block heat to reduce AC load, filter UV rays to protect skin and prevent interior fading. I feel more secure and comfortable during daily driving, even on bumpy roads without worrying about glass breakage. Regularly inspect the film for damage or bubbling, and replace promptly if issues arise to extend service life.
Last summer, right after I got my new car, I went to apply explosion-proof film, choosing to cover all the side windows including the rear windshield, and the difference was immediate—driving no longer felt like being roasted. Even coverage is crucial; during my previous DIY attempt, I didn’t apply it well, resulting in bubbles at the edges. Later, a professional taught me to clean the glass thoroughly before application to ensure a firm, gap-free adhesion. After installation, the heat insulation effect was remarkable—the car cooled down faster when parked under the sun, and privacy improved as outsiders couldn’t see inside. For the front windshield, I used a semi-transparent film, carefully measuring the position to avoid obstructing the view while complying with local regulations. The film is applied directly onto the glass surface, and daily maintenance is simple—just wipe with a soft cloth dampened with water, avoiding harsh chemical cleaners to prevent damage. Now, even on long drives, my family praises the increased comfort, with less direct sunlight reducing fatigue.
