Sprayable Soybean Foam Technologies

 

 

Description Of Wall

During October and November 2006 ORNL tested a new improved type of the soybean-based foam. Innovative wall insulation configuration, which consists of 1-in. thick layer of sprayed soybean foam and cotton insulation batts, was designed to be used in wood and steel-framed wall assemblies.

During October and November 2006, wall assembly using Smith Bucklin-United Soybean Board-JEC Wall Technology was constructed and tested in the ORNL guarded hot-box using ASTM C-1363 procedure. For more information about hot-box test results please visit ORNL Hotbox Test R-value Database.

Sprayed soybean-based foam was installed in the wall cavities with average thickness about 1-in. Thermal conductivity of the fresh foam was tested using ASTM C518 test method.
