Is it necessary to apply film on double-silver coated glass?

It is still necessary to apply film on double-silver coated glass. Introduction to coated glass: Coated glass, also known as reflective glass, involves coating one or multiple layers of metal, alloy, or metal compound films on the glass surface to alter its optical properties and meet specific requirements. Based on different product characteristics, coated glass can be categorized into the following types: heat-reflective glass, low-emissivity glass, conductive film glass, etc. Production methods of coated glass: Vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. Magnetron sputtering coated glass utilizes magnetron sputtering technology to design and manufacture multi-layer complex film systems, allowing for the application of various colors on white glass substrates. The film exhibits excellent corrosion resistance and wear resistance, making it one of the most widely produced and used products. Vacuum evaporation coated glass, in terms of variety and quality, falls short compared to magnetron sputtering coated glass and has gradually been replaced by vacuum sputtering methods.

I think this is a pretty common issue. As someone who enjoys traveling with family, I particularly value comfort and safety when driving. The double silver-coated glass itself is excellent—it effectively blocks UV rays and heat, preventing the car from turning into an oven in summer and offering good skin protection. However, I still choose to apply a tint film because it adds privacy, making it harder for outsiders to see inside, which gives me peace of mind when my kids are in the back. The film also has anti-shatter properties, preventing glass fragments from flying in case of breakage, which is especially useful in minor accidents. An added benefit is glare reduction, making long drives easier on the eyes. When choosing a film, pay attention to light transmittance—lighter tints don’t affect nighttime driving. Once applied, it requires minimal maintenance; just be careful not to scratch it during car washes. Spending a little extra for safety is well worth it, and I recommend considering professional brands.

As a young car owner, I value both personality and practicality in driving. The dual-silver coated glass already provides excellent heat insulation, reducing temperature fluctuations inside the car and protecting against UV damage. However, window tinting makes the car look cooler—I opted for dark tint for a stylish appearance and enhanced privacy, so others can't see what I have inside. The tint also reduces glare, making daytime driving more comfortable without needing sunglasses. From a safety perspective, high-quality film reinforces the glass against shattering, offering better protection in case of a collision. After tinting, the air conditioning works slightly more efficiently, saving a bit of fuel. The downside is the cost, ranging from a few hundred to over a thousand, and maintenance requires care to avoid scratches. For young people, this small investment for multiple benefits is quite worthwhile—just make sure to choose reputable brands and avoid cheap options.

Having driven for many years and being frugal with household expenses, I find that double-silver coated glass provides sufficient functionality without the need for additional window film. It offers strong heat insulation and UV protection, and car manufacturers have already considered energy efficiency and safety in their designs. Spending extra on film is unnecessary and could waste hundreds or even thousands. If the film is of poor quality, it may darken nighttime visibility, posing risks. I once used light-colored film and found it troublesome when driving in the rain due to blurred vision. Cleaning windows also becomes more difficult after applying film, and improper washing can cause bubbles. If privacy or explosion-proofing is truly needed, opting for reinforced original glass is more economical. Saving this money to buy car accessories or for vehicle maintenance is much more practical. The best way is to keep life simple.
