Nope, not in the industry. I'm a professional engineer working in the environmental consulting industry. Being a geological engineer, I have an extensive background in hydrogeology which is the study of the movement of groundwater through porous rocks and soil. In other words, the movement of water through porous media. The same principles apply whether you're talking about the infiltration and movement of water through porous sandstone or styrofoam. To me, a low permeability clay layer sitting atop a porous and permeable sandstone or gravel layer and insulating/protecting it from the downward migration of a contaminant under the force of gravity is the exact same thing as a water resistant poly sheet being wrapped around a porous polystyrene board in order to slow down the rate at which water infiltrates the board in a high vapour pressure environment. It's pretty much the exact same thing happening in both cases, just different physical settings.
My engineering education also gave me a little background in electricity and circuit design and my own curiousity and fascination for figuring out how things work coupled with the diverse and well rounded education I got in engineering school has enabled me to understand how my hot tub's control systems work and since all hot tubs generally work the same way, I can apply this understanding to other hot tub control systems.
