Agriboard SIPs utilize agricultural waste, wheat, and rice straw as an insulating core. More than 80% of Agriboard’s panels consist of straw left over after the grain has been harvested. The perimeter LSL presents a high shear-strength panel with virtually no thermal bridging. The 7?7/8-inch-thick panels have a dynamic R-value of up to 25.4. Any straw waste from the construction process can be reused as landscape mulch. 866.247.4267.
