Описание: Showing the real strength of insulated concrete walls compared to traditional construction, Greenblock put their product to the test versus a 2x4 cannon firing 75mph projectiles. While the Greenblock wall shrugged off these projectiles without any real damage, the wood and hollow concrete block walls couldn't even withstand a blow from the cannon when turned down to 50mph.
