CertainTeed engineered its AirRenew gypsum board to convert airborne formaldehydes into safe compounds, improving indoor air quality. A full-bodied latex primer must be applied prior to painting. Enhanced to prevent moisture and mold, the wallboard is as lightweight and as easy to install as regular gypsum board, CertainTeed says. It also requires no special tools to cut or install. 800.233.8990. www.certainteed.com.
