Housewrap

Housewrap: What You Need to Know

Housewrap, also known as weather-resistant barrier (WRB), is a protective layer installed between a building's sheathing and exterior siding. It prevents moisture infiltration while allowing water vapor to escape, reducing the risk of mold, rot, and structural damage. Designed to enhance energy efficiency and durability, housewrap is a key component in modern construction.

Key Features:

• Weather Protection: Housewrap acts as a barrier against wind-driven rain and moisture, preventing water penetration while maintaining breathability. By stopping liquid water from entering the structure while allowing vapor to escape, it helps reduce the likelihood of mold growth and wood decay, making it an essential component for long-term building integrity.
• Energy Efficiency: Housewrap minimizes uncontrolled air movement and drafts, enhancing the effectiveness of insulation materials. By reducing heat loss in winter and heat gain in summer, it contributes to lower energy consumption and improved indoor comfort, helping homeowners and businesses cut down on heating and cooling costs.
• Tear and UV Resistance: Engineered for durability, housewrap withstands exposure to harsh conditions during the construction phase, such as wind, rain, and temporary sunlight before exterior siding is installed. Many housewrap products feature reinforced fibers or coatings to resist tearing and ensure structural integrity during handling and installation. While advanced housewraps often offer tear and UV resistance, building paper does not possess these features. However, it remains a dependable option for basic moisture protection when used in covered or sheltered applications. Proper installation ensures long-term performance once covered by siding.

Applications:

• Residential Construction: Used in homes to create a continuous protective layer that prevents moisture intrusion and enhances insulation.
• Commercial Projects: Applied in large-scale buildings to maintain structural integrity and meet energy efficiency requirements.
• Retrofit and Remodels: Ideal for upgrading older buildings with improved moisture management and air-sealing benefits.

Types of Housewrap:

• Woven Housewrap: Constructed from high-strength woven plastic fibers, this housewrap offers excellent tear resistance and durability. With a size of 9 ft. x 150 ft. (1350 sq. ft.), it is an ideal choice for large-scale residential and commercial projects. It provides robust protection against air infiltration and moisture penetration, making it suitable for high-wind areas and long-term performance needs.
• Non-Woven Housewrap: A versatile and lightweight housewrap designed for enhanced moisture management and breathability. While not visible in this specific product range, non-woven housewraps are typically used in climates requiring balance between water resistance and vapor permeability. This option would be ideal for smaller-scale or specialized applications.
• Drainable Housewrap: Featuring a textured surface that efficiently channels water away from the structure, this housewrap enhances moisture control in humid or rainy regions. Although not listed here, it complements siding materials where additional drainage is required, ensuring long-term protection.
• Building Paper: Made from asphalt-saturated kraft material, building paper is an affordable and versatile moisture-resistant option commonly used in residential construction. Available in grades like 2-Ply, it provides varying levels of durability and protection, making it suitable for applications such as underlayers for stucco, wall insulation, and temporary weatherproofing during construction. Its cost-effectiveness and ease of installation make it a reliable choice for projects requiring basic moisture control without the expense of advanced housewraps.
• Housewrap Tape: Used to seal and secure housewrap during installation, this essential accessory ensures seams are tightly closed, preventing air and water leaks. Typically offered in widths like 1.88 in. and 2 in., housewrap tape strengthens the integrity of the moisture barrier.
• Flashing Membrane: Designed to create watertight seals around windows, doors, and other openings, flashing membranes work alongside housewrap for complete moisture protection. Available in widths like 6 in. and 9 in., they are critical for preventing leaks and maintaining energy efficiency.

Installation Considerations:

• Proper Overlapping: Ensure seams are overlapped and taped to maintain a continuous moisture barrier.
• Fastening Methods: Use cap nails or staples designed for housewrap to prevent damage and ensure secure installation.
• Exposure Limits: Avoid prolonged UV exposure beyond manufacturer recommendations to maintain material integrity.
