For a stucco homeowner, moisture buildup due to insufficient ventilation or drainage may cause damage to your home’s sheathing and framing, which can compromise the structural integrity of your home. Moisture intrusion can always be a challenge. Consider a siding product, such as a well-designed lap siding, that can resist damage from moisture and help manage moisture on the walls of your home.
HardiePlank® HZ5® lap siding has proven to deliver on design and performance. The HZ5 fiber cement products are specifically Engineered for Climate® to resist shrinking, swelling and cracking even after years of wet or freezing conditions. The unique HZ5 product formulation and manufacturing process combined with proven installation best practices, work together to help manage moisture and resist mold and water damage. The advanced design of the HZ5 lap siding profile improves drainage from top to bottom. The positive slope at the top drains moisture to the outer face of the siding. The drip edge at the bottom allows moisture to drain away from the lap. This design, coupled with installation best practices, such as the use of joint flashing, will help your siding better manage moisture accumulation.
