Abstract	We present a methodology for creating a simulated foam microstructure for use in forward simulations of wave equations to quantitatively analyze the expected scattering phenomenon primarily responsible for the attenuation of interrogating signals in Sprayed-On Foam Insulation (SOFI). Our approach builds off of the popular use of Voronoi Tessalations for crystal growth modeling by using the Laguerre variant (Apollonius Graph) applied to close-packed spheres. A fi lled-in random raindrop algorithm is used to generate the packing confi guration. Lastly, variation of diameter mean values is used to model knitlines, i.e., the interfaces between sprayed-on layers.
