Polystyrene has been around for nearly 200 years, having first been discovered in 1839 by German apothecary Eduard Simon when he isolated a substance from natural resin. So, there has since been plenty of time to find many different uses for polystyrene. And while there’s plenty of obvious examples, there are also a few you might not have thought of.
Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist heat flow. Highly reflective foils in radiant barriers and reflective insulation systems reflect radiant heat away from living spaces, making them particularly useful in ...
