NADRA: Fortress Building Products is celebrating 20 years of delivering wood-alternative outdoor building products, people-first programs and unlimited design possibilities. A family business, Fortress Building Products was born out of Woodmark International. In its early years, the company’s goals were modest: deliver product-focused solutions to its customers. But as the company grew to meet increased customer demand, it became clear that there was an opportunity for Fortress® to help lead positive change on a local and global scale.
