Louisiana Pacific says wood siding is better than cement board siding on homes - at least when it comes to firing a baseball, golf ball, rocks and marbles at speeds up to 102 miles per hour.

LP Building Products asked the National Aeronautics and Space Administration (NASA) to evaluate the impact damage resistance of engineered wood siding from the LP SmartSide brand and fiber cement siding.

Impact damage resistance was compared by impacting each type of siding with golf balls, baseballs, marbles and rocks. According to NASA: “Under similar conditions, with all four projectiles more damage was sustained by the fiber cement siding product than the engineered wood siding product.”
