Why you should soundproof your car? Car body metal hardening


Minor car accidents, hail showers, stone damages, children playing in the yard - we can ding up a car almost everywhere. The deeper the dent is, the harder it is to repair, and the defect can still remain visible afterwards.

Year after year, the number of cars in our cities is growing; the same can’t be said for parking spots. Imagine busy parking near shopping malls on Saturdays, or the attempts to squeeze into a parking space somewhere in the vicinity of your office in the downtown in the weekday morning. Minor accidents, scratches, dents are commonplace.

If a car is kept outside, you can easily add some more “opportunities” - children on bicycles, hail showers, a branch fallen from the tree… If a car is parked near a lawn - expect lawn-mowers with their string trimmers and flying stones. And even if you are a happy owner of a garage, nobody is immune to stone damages while driving.

The degree of damage to a car in all these cases depends on the car body sheet metal thickness. With the development of the car industry, the growth of the cost of materials and safety requirements strengthening, this value has significantly reduced. For example, the 1940s - 1960s cars had 1-2 mm body sheet metal, while in modern cars it usually doesn’t exceed 0,6 - 0,8 mm. But do not get too nostalgic lamenting about supposedly safe thick-walled old trucks. On the contrary, the design of modern cars takes into consideration various features affecting passive safety, which the cars of previous generations fail to compete with.

However, in the case of small accidents, a thicker metal of a car body would be deformed not so severely. As the evidence from practice shows, roof, doors and hood are the parts which are more likely to be dented or scratched.

The specialists of Standartplast use the data of scientific research to create the materials which are perfect for each particular zone. For a hood, professionals usually use 2 mm thick Aero; for doors - 15 mm thick Biplast, 6 or 10 mm thick Accent, for a roof - Aero and Biplast. Thus, car body thickness increases significantly, but not at the expense of increasing metal thickness that would have a negative impact on safety.

Our engineers and laboratory scientists test and challenge materials regularly. These tests and challenges sometimes go beyond the traditional boundaries, but they vividly demonstrate the effectiveness of our products. For example, we performed an experiment with a rifle, a bow and a crossbow, and shot the targets covered with our materials to estimate the damage comparable to that from heavy hail showers or a stone. The experiment showed that the targets with our materials were deformed not so severely as those without protection.

Of course, sound insulation will not prevent the consequences of hail showers or other similar accidents, but it can significantly reduce damage scale and help you save on repairing.
