Some hybrids have high-density polyfoam rails around the perimeter ... By comparison, closed cell foam is rigid, dense, and water-resistant, with minimal airflow since the cells are tightly ...

Researchers have used machine learning to design nano-architected materials that have the strength of carbon steel but the lightness of Styrofoam. The team describes how they made nanomaterials with ...

The HercuWall system uses EPS foam, the same foam that is used as stucco backer board and is expanded into large blocks of a pound and a half density ... On top of the high R-value rating ...
