Product Summary
HardieWrap weather barrier provides a balance of water resistance and breathability, reducing water intrusion while allowing water vapor from inside your home to escape. This keeps the area within your walls dry.
HardieWrap Pro-Flashing is a butyl rubber self-adhesive designed to peel and stick around windows and doors to prevent water and air intrusion. It also self-seals around fasteners.
HardieWrap Flex Flashing is designed to easily stretch and seal around custom shapes — including windows and doorsills — to prevent water and air from entering the building.
HardieWrap Seam Tape is designed to seal vertical and horizontal seams and small holes in the weather barrier to prevent air and water infiltration.
Construction and Materials
James Hardie's HardieWrap® Weather Barriers are engineered to provide a robust defense against the elements for residential and commercial building envelopes. Designed as a critical component of the James Hardie building system, these weather barriers are intended to work seamlessly with their fiber cement siding products, offering comprehensive protection.
Construction and Materials
The HardieWrap® Weather Barriers are constructed with a focus on durability and performance. While specific material compositions can vary slightly between different product lines within the HardieWrap® family, the core design emphasizes a balance of water resistance and vapor permeability.
- Material Composition: Typically, these barriers are multi-layered products that often include a non-woven fabric or a reinforced cellulosic material. These layers are engineered to create a continuous barrier against liquid water intrusion, preventing it from reaching the sheathing and framing.
- Permeability: A key characteristic of HardieWrap® products is their breathability. They are designed to be vapor-permeable, allowing moisture vapor that may become trapped within the wall cavity to escape. This property is crucial for preventing the buildup of moisture, which can lead to mold, mildew, and structural damage over time.
- Durability and Strength: The materials used are selected for their resistance to tearing and puncturing, which can occur during installation or from impact. This ensures the integrity of the barrier is maintained throughout its service life.
- UV Resistance: Some HardieWrap® products are formulated to offer resistance to ultraviolet (UV) radiation. This is important as the weather barrier may be exposed to sunlight for a period before the exterior cladding is installed, and UV exposure can degrade certain materials.
Product Range and Features
James Hardie offers a range of weather barrier solutions, each designed to meet specific building code requirements and performance expectations.
- HardieWrap® Flex: This product is known for its flexibility, allowing it to conform easily to contours and corners of the building envelope. This adaptability helps in creating a more seamless and effective barrier, particularly in areas with complex geometries.
- HardieWrap® Commercial: Designed for the demands of larger construction projects, this option often provides enhanced durability and robust protection suitable for commercial applications.
- Integrated Systems: HardieWrap® weather barriers are intended to be part of a larger building system. They are designed to work in conjunction with other components, such as flashing tapes and sealants, to create a complete air and water-resistive barrier.
The installation of HardieWrap® Weather Barriers typically involves mechanical fastening, such as stapling or nailing, directly to the building's structural sheathing. Proper lapping and sealing of seams are essential for ensuring the continuity and effectiveness of the barrier.
