Measuring Drywall Against Environmental Standards

ULE ISR 100 provides a life-cycle-based approach to the evaluation of gypsum board—taking into account the material extraction and manufacture of the product as well as toxicity, durability, and end-of-life management.

“It’s a science-based standard,” said Bill Hoffman, Ph.D., a senior scientist at ULE. He was directly involved in the development of ISR 100, which he says relied heavily on data coming out of the gypsum industry. The standard also puts emphasis on continued data collection, with prerequisites and points based on life-cycle assessment (LCA), baseline data, and explicit disclosure of all ingredients down to 0.1%, or 1,000 parts per million (ppm), of the total product.
