  • Insulated with organic straw from Plainville Farm in Hadley, MA, our wall panels provide superior thermal performance and carbon sequestration. They are designed to fit a variety of architectural styles and construction methods, ensuring both sustainability and aesthetic appeal.

  • Our floor panels utilize open web trusses and wood fiber insulation, offering flexibility for different construction types. They can be used on pier or full foundations, providing a sturdy and insulated base for any structure.

  • Roof panels are insulated with wood fiber and can be designed to accommodate trusses or structural ridge beams. This flexibility allows for diverse roof configurations while maintaining excellent insulation properties.

  • Our panels can be tailored to show off selectively exposed timber elements, making the structure a visible and integral part of the design, or hide the structural elements entirely within the panel for a seamless finish. This versatility ensures that our panels meet the aesthetic and functional needs of any project.
