New types of engineered wood are ready for building sites

Could your house take a bullet for you?

Clad it with a new type of modified wood, and it might, says Alex Lau, co-founder and executive chairman of InventWood.

The US-based company has developed Superwood - a modified wood it claims is stronger than steel.

During lab tests, a gas gun fired a bullet-like projectile at thin pieces of wood, including an early version of the company's product.

While the projectile blasted straight through the natural wood, it failed to penetrate the heavily modified version.
