Brick Veneer Offers More Protection

Video 1 of 3 - See Fiber Cement and Vinyl Video

This video shows that homes built with brick offer dramatically more protection from wind-blown debris than homes built with vinyl or fiber-cement siding. The study, conducted at the Wind Science and Engineering Research Center at Texas Tech University, demonstrated that a medium-sized wind-blown object, such as a 7.5-foot long 2 x 4, would penetrate walls clad with vinyl or fiber-cement siding at a speed of 25 miles per hour (mph). By comparison, the same object would need to travel at a speed exceeding 80 mph in order to penetrate the wall of a brick home.

In a test that simulated wind-blown debris traveling at a speed of 34 mph, the 2 x 4 bounced off the brick veneer with no damage to the interior wall. When the same test was conducted on a vinyl or fiber-cement sided wall, the 2 x 4 easily penetrated the wall, with more than five feet of the timber passing through the interior wall. The test was representative of debris that would be generated at wind speeds between 100 and 140 mph.

All walls shown in these videos are of typical residential construction: 2x4 studs with fiberglass insulation between them, gypsum board on the inside of the studs and OSB sheathing on the outside of the studs. The only difference in the walls is the exterior cladding.

I'm extremely surprised to hear this; the building was probably not constructed properly. Why? Because the Wind Science and Engineering Research Center, part of Texas Tech University, conducted these tests under strick control conditions. Their tests concluded that a 7.5 foot 2X4, weighing about 9 pounds, would have to travel over 80 miles per hour to penetrate a wall system with brick veneer. The same 2X4 penetrates both fiber cement and vinyl siding walls at 25 m.p.h. Stephen Sears - BIA

I like how the camera flash fires so late...lol

oh come on that just left the gun at 35 mph i have seen video were the same stick takes out ten bricks,
