- Wood nail welds are the
- foundation of wNLT
- technology. Wood nails
- driven at high-velocity
- with a pressurized nailer
- burn the wood substrate
- and create a solid wood
- “lignin” weld that
- improves wood nail pull
- out resistance. Pull-out is
- limiting factor for metal
- nails.
Wood fasteners offer significant advantages during pre-fabrication with CNC routing equipment, which would otherwise be damaged by metal nail fasteners.
Removing metal fasteners after a wood building’s useful life is an obstacle to recycling wood buildings. Downstream applications for recycled wNLT panels are possible saws are not damaged by wood nails.
Without metal fasteners, wNLT is viable for composting and biofuel applications.
