Shock resistant

Surprise! 10 times destruction high.

An examination to fall to a roof tile with an iron ball.

As for the result, that becomes all for about 10 times destruction high. The air roof made a hybrid in PVA fiber has strongstrength.

Shock strength increases square of the height that an iron ball falls for uniform acceleration. Therefore, destruction high 10 doubles.

There becomes little breaking of the roof tile by the flying thing at the time of the disaster.
In the residential areas to crowd, a flying thing destroys a tile, and a roof tile drops. The air roof can minimize the damage of the second disaster.

The air roof does not become it in this way!!!
