Home Slicker Plus Typar: A Practical Guide to Exterior Drainage and Weather Barriers

Home Slicker Plus and Typar represent two key components in modern exterior wall systems. Home Slicker Plus functions as a drainage plane and rain screen underlayment, while Typar serves as a breathable weather-resistive barrier that protects sheathing from moisture while allowing vapor to escape. When used together or chosen with compatible siding systems, they help prevent water intrusion, improve drying potential, and support long-term durability. This article explores how these products work, how they compare, and best practices for selecting and installing them on residential projects in the United States.

What Is Home Slicker Plus?

Home Slicker Plus is a drainage and weather-resistive barrier designed to sit behind siding and create a continuous air-gap drainage plane. Its textured surface reduces capillary draw and helps water shed away from the wall assembly. The product typically includes a mesh or lattice-like backing that creates an air channel, promoting airflow and helping to fast-track moisture out of the wall cavity. This design can reduce the risk of moisture-related problems such as mold, mildew, and wood rot, especially in regions with high precipitation or humidity.

Key benefits include enhanced drainage, improved drying potential, compatibility with various siding materials, and reduced risk of capillary moisture transfer. For homeowners, the main value is added protection against water intrusion and a longer-lasting exterior finished system.

What Is Typar?

Typar is a breathable weather-resistive barrier (WRB) used as an exterior sheathing wrap. It’s engineered to block liquid water while allowing water vapor to escape, which helps to prevent moisture buildup inside wall cavities. Typar products typically feature an advanced membrane and fabric combination that resists tearing, UV exposure during construction, and impact from wind-driven rain. Typar wraps are commonly used beneath cladding systems such as vinyl siding, fiber cement, and wood siding, providing a continuous protective layer around the structure.

Key benefits include high tear resistance, reliable moisture management, and compatibility with a wide range of siding options. When properly installed, Typar contributes to durable, energy-efficient walls with improved long-term performance.

Choosing Between Home Slicker Plus and Typar

Choosing between these products—or deciding how to pair them—depends on climate, siding type, and project goals. Home Slicker Plus offers a dedicated drainage plane with an air gap behind the siding, which can be advantageous in situations with heavy rainfall or poor drainage conditions. Typar provides a robust WRB that protects the wall from liquid water while permitting vapor diffusion, which is essential in climates with humidity fluctuations or rapid temperature changes.

In some projects, professionals use Typar as the primary WRB and incorporate a separate drainage plane behind the siding. In others, a drainage-based system like Home Slicker Plus is installed in conjunction with a WRB to maximize moisture-management performance. It’s essential to follow manufacturer guidelines for compatibility and installation to ensure the wall system performs as intended.

Installation Considerations

Successful installation of either product—or a combination—depends on meticulous detailing at penetrations, corners, windows, and door openings. The following steps summarize best practices for typical residential installations in the United States.

• Surface prep: Ensure sheathing is clean, dry, and free of protrusions or sharp edges that could damage the WRB or drainage plane.
• Seaming and overlaps: Follow manufacturer guidelines for overlap distances. Typically, WRB overlaps are east-west to facilitate drainage, and drainage-plane products require alignment that maintains a continuous path for water to exit the wall cavity.
• Fastening: Use corrosion-resistant nails or staples and ensure fasteners don’t compress the barrier. Leave proper gaps as specified to avoid tearing or buckling.
• Flashing and penetrations: Install flashing at windows, doors, and roof lines to direct water away from the wall. Seal all seams and overlaps around penetrations with approved tapes or sealants.
• Siding installation: Install siding over the drainage plane or WRB per siding manufacturer instructions. Maintain air gaps and avoid direct contact between the siding and the barrier where the design specifies an air space or drainage gap.
• Climate considerations: In wet climates, prioritize continuous drainage paths and robust WRB performance. In cold climates, ensure vapor management aligns with insulation and interior humidity controls.

Performance And Practicality: What to Expect

Both Home Slicker Plus and Typar aim to reduce moisture-related risks, but their performance characteristics differ. Home Slicker Plus emphasizes a physical drainage plane that creates an air gap for moisture to escape. This approach can be particularly beneficial in installations with heavy rain exposure or where moisture management is a primary concern. Typar focuses on vapor permeability and liquid water resistance, providing a strong barrier against infiltration while allowing the wall to dry interiorly.

For homeowners, the practical implications include improved wall durability, reduced risk of moisture-related damage, and potential energy efficiency benefits through better drying potential. Additionally, proper installation reduces the likelihood of wind-driven rain infiltration and helps maintain the integrity of the insulation and framing over time.

Cost And Longevity Considerations

Material costs vary by brand, thickness, and regional supplier pricing. Generally, drainage-plane systems may incur slightly higher material costs than basic WRBs, but they can yield long-term savings through reduced maintenance and fewer moisture-related repairs. Typar WRBs typically offer competitive pricing and excellent durability, with a track record of reliable performance across a range of climate zones. When budgeting, consider:

• Material costs: Compare price per square foot and required accessory components (tapes, fasteners, flashing).
• Labor: Drainage-plane installations may require additional time for sequencing with siding and flashing details.
• Warranty: Review manufacturer warranties for both WRBs and drainage planes, including coverage for installation defects and environmental exposure.
• Climate suitability: Match product choice to local weather patterns to maximize longevity and reduce maintenance needs.

Maintenance, Inspection, And Longevity

Routine inspections after severe weather events help identify issues before they escalate. Look for signs of moisture intrusion, blistering, tearing, or gaps in seams and flashing. Regular exterior maintenance—such as cleaning, resealing, and resealing flashing joints—helps maintain barrier performance. If a siding replacement or major exterior renovation occurs, reassess the WRB and drainage plane installation to ensure continued compatibility and efficacy.

Both Home Slicker Plus and Typar are designed for durability, but their long-term performance relies on proper installation, appropriate climate considerations, and timely maintenance. Staying informed about local building codes and climate-specific recommendations is essential for maximizing wall-system longevity.

Best Practices For Homeowners And Builders

• Consult product documentation: Always follow the latest installation guides from the manufacturers for Home Slicker Plus and Typar to ensure compatibility and warranty validity.
• Coordinate with siding choices: Ensure your siding system is compatible with the chosen drainage plane or WRB and that ventilation gaps are respected.
• Plan flashing details early: Address windows, doors, and corners upfront to prevent moisture intrusion points and ensure clean water drainage paths.
• Prioritize climate-appropriate solutions: In humid or wet regions, emphasize drainage and vapor management to reduce condensation risks.
• Document and maintain: Keep installation records and schedule periodic inspections to maintain system performance over time.
