On this project Universal Foam Products provided 3" EPS Sheets at 1.8 pound density per cubic foot as foundation insulation. Our customer located in Burnsville, MN was building a garage out of stone and concrete using the Slipform Technique. The slipform technique helps with a consistent and continuous pouring of the concrete to the moving formwork. The next step is to then work on the walls and build up with the same formwork.
Expanded Polystyrene is a great economical insulating material. The .9 lb density has an R-Value starting at 3.85/inch with the highest density of EPS at 2.85 lb per cubic foot having an R-Value of 4.6/inch.
