The Peru manufacturing plant produces both interior and exterior fiber cement building products. The facility houses various operations, including production from raw materials; finishing (curing and coatings); and on-site testing for durability and aesthetics. In addition to standard HardiePlank® HZ5 production, Peru is home of the Hardie Trim® NT3 product as well as a provider of ColorPlus® Technology.

Peru plant employees support numerous charities and charitable activities, including building Habitat for Humanity homes; donating funds to two local pantries; providing school supplies to underprivileged students; supporting the local March of Dimes chapter; donating funds to a youth service bureau; and raising funds for the local Junior Achievement chapter, which provides additional educational opportunities for students.
