In an extraordinary development for sustainable construction, Superwood has emerged as a revolutionary material that combines the eco-friendliness of wood with strength surpassing traditional building materials. This innovative product, developed by InventWood after a decade of research at the University of Maryland, represents a significant leap forward in sustainable building technology.
How Superwood is made
The creation of Superwood involves a sophisticated two-step process that transforms ordinary wood into an extraordinarily strong material:
- Chemical treatment using sodium hydroxide and sodium sulphite
- Hot-pressing technique that collapses cellular structure
- Alignment of cellulose nanofibers for enhanced strength
This process effectively removes lignin while preserving and strengthening the cellulose structure, resulting in a material with remarkable properties.
Remarkable strength and durability
Superwood’s impressive characteristics have caught the attention of construction and engineering experts worldwide:
- Up to 10 times stronger than steel by weight
- 6 times lighter than traditional steel
- Exceptional resistance to water, fungi and insects
- Class A fire rating with self-extinguishing properties
- Superior dent and scratch resistance
Environmental benefits
The environmental advantages of Superwood make it particularly attractive for sustainable construction:
- 90% lower carbon emissions compared to steel production
- Utilises underutilised or waste wood materials
- Promotes sustainable forestry practices
- Reduces overall construction carbon footprint
Commercial applications
Superwood’s versatility opens up numerous possibilities across various sectors:
- Structural building components
- Exterior façades
- Protective barriers
- Landscape applications
- Lightweight construction materials
The future of construction
Currently manufactured in a 90,000-square-foot facility in Frederick, Maryland, Superwood represents the future of sustainable building materials. While its current cost ranges from $12.5-$25 per pound compared to steel’s $1-2 per pound, ongoing research and development efforts aim to make it more cost-competitive.
The introduction of Superwood marks a significant milestone in construction technology, offering a sustainable alternative that doesn’t compromise on strength or durability. As production scales up and costs decrease, this innovative material could revolutionize how we build our future infrastructure.
