In our past posts we have pointed out a great many advantages that Polyurethane SIPs have over Polystyrene. Today we would like to dedicate our space to an article that we found in the Building Green newsletter. We consider this of the upmost importance as it concerns the dangerous chemical compositions that make up polystyrene. Please be sure to click on the image to read the whole article.

We do disagree with one point in the article. The article indicates that it is more difficult to get varying thicknesses with a polyurethane panel than a polystyrene panel. At Earthcore we can provide panels in varying thicknesses from 4″ to 12″ giving our customers a choice of thicknesses to choose from.
