Is Hardiplank banned in California?
• A: No. Despite consistent rumors, Hardiplank is not banned in California or any other state. • Q: What should be attached to the studs before Hardiplank is attached. • A: We recommend a moisture barrier like Dupont® Tyvek® (or similar) that “breathes” and allows air to travel but keeps out moisture. Depending on the condition of the substrate and/or studs that exist, a plywood or OSB can be installed first, then the moisture barrier. Usually, plywood or OSB is required if the wall studs are more than 24″ on center. A complete of inspection of the condition and replacing of any damaged or rotten studs should always be performed first.
