In another installment of Material World, we attempt to dent four types of siding, in the name of science of course.

Today we are testing the impact resistance of different types of siding using a 50 caliber steel shot bb, a wrist rocket slingshot, and Josh’s impeccable aim.


Vinyl siding is typically a much more affordable option than other sidings like brick or wood. Its need for little maintenance makes it a great cost-effective choice as well. When it came to facing a 50 caliber bb though, not your best bet. The vinyl siding was tested first, and the bb tore a hole right through. A gaping, irreparable hole was left behind. Ouch!

Fiber Cement (pre-finished)

Fiber cement is another affordable siding choice. It’s low maintenance, fire and termite resistant, and is very versatile aesthetically. The fiber cement faired much better than the vinyl, but still left a sizable dent in the siding. About half the bb’s width fit in the dent, but there was no breakage or cracking.

Engineered Wood Siding (pre-finished)

Engineered wood is a great alternative to real wood siding. It’s more flexible, lighter, and moisture resistant, but keeps that natural wood look. The engineered wood siding had the best turn out in our impact resistance test. We could barely find the mark left behind!

Steel Siding

Steel is a highly durable siding that can withstand more damage than other materials. In our test, it did fair better than both the vinyl and fiber cement, but there was still a decent sized concave dent in it, with some slight paint chipping.


Based on how the sidings faired during this experiment, Josh ranked the sidings in the following order:

  1. Engineered Wood Siding
  2. Steel Siding
  3. Fiber Cement siding
  4. Vinyl Siding
