Superwood Explained: InventWood CEO Answers Key Questions on New Material

What is Superwood?

• 💡 Superwood is a revolutionary material derived from wood, engineered to be lighter and stronger than steel, with the ability to even stop bullets.
• 🚀 This innovative product holds the potential to transform the construction industry and many other sectors.
• ✅ InventWood is the company currently beginning to produce Superwood commercially in the US.

How Superwood is Made

• 🔬 The process involves taking regular wood and first boiling it in a chemical solution (sodium hydroxide and sodium sulfide) to partially remove lignin and hemicellulose, leaving cellulose intact.
• ⚙️ Following chemical treatment, the wood is compressed and gently heated, causing cell walls to collapse and forming strong chemical bonds between cellulose nanofibers.
• 💪 This densification process results in a material that is twice as strong as steel.

Durability & Practicality

• 🐜 Termite resistance was confirmed through US Forest Service tests, where insects either ignored Superwood or died attempting to penetrate its dense structure.
• 💧 While still hydroscopic, Superwood is less prone to expansion and contraction than regular wood and can be treated for enhanced water resistance.
• 🛠️ Working with Superwood requires carbide blades for cutting and pre-drilling for fasteners like screws, though high-pressure nailers can also be used.

Material Sourcing & Environmental Impact

• 🌱 Superwood can be produced from various wood types, including poplar (currently used), bamboo, softwoods, and even recycled or diseased timber.
• 🌍 InventWood aims to be a mission-driven company, promoting the efficient use of natural resources and utilizing less valuable wood that might otherwise go to waste.
• 🌳 This approach could lead to positive environmental impacts by using existing supply chains and reducing landfill waste.

Applications & Future Outlook

• 🎯 Superwood is best suited for applications that leverage its unique strength, aesthetics, or fire resistance, such as fire-resistant building materials, decks, and fences.
• 🔥 It offers a fire-resistant alternative to traditional wood in areas prone to wildfires, providing both safety and natural beauty.
• 📈 While initially focused on a quality model to demonstrate its value, the company anticipates that Superwood will become more accessible and cost-effective over time, similar to Tesla's market strategy.
