The HZ5® product line is right at home in climates with freezing temperatures, seasonal temperature variations, snow and ice. HZ5® boards are the result of our generational evolution of our time-tested products. We’ve evolved our substrate composition to be specifically designed to perform in conditions found in these climates. 

To ensure that its beauty matches its durability, we’ve engineered the surface for higher performance, giving it superior paint adhesion and moisture resistance. In addition, we’ve added a drip edge to the HardiePlank® HZ5® lap siding product to provide improved water management in conditions specific to HZ5® climates.
