TamlynWrap® Elite 9' x 125' - 1125 sqft/roll

TamlynWrap Elite WRB — Residential Water Resistive Barrier for All Cladding Systems

TamlynWrap Elite WRB (Item ID: TWE9X125) is a residential-grade, non-perforated Water Resistive Barrier combining a non-woven backing with a durable coating to deliver a balanced performance profile: moisture resistance, air infiltration protection, vapor permeability, and wind and tear resistance. Engineered for use behind all cladding systems across all climate zones, it is an economical solution for contractors who require code-compliant moisture management without sacrificing performance. Each roll covers 1,125 square feet at 9 ft wide by 125 ft long, weighing 22 lbs.

Unlike perforated housewraps that rely on micro-holes for vapor transmission, the Elite WRB achieves a perm rating of 20 through its coated non-woven structure — eliminating puncture-point vulnerabilities while maintaining the vapor drive needed to dry wall assemblies. It meets or exceeds all residential code requirements and conforms to ICC-ES AC38 acceptance criteria, UL STD CCRR-0520, and CSA STD, making it a straightforward specification for jobs requiring documented code compliance.

Key Features & Benefits

High Vapor Permeability (Perm Rating of 20)

A perm rating of 20 ensures adequate vapor drive outward through the wall assembly, allowing trapped moisture to escape rather than accumulate. This actively mitigates conditions that lead to mold, rot, and premature degradation of structural sheathing — a critical consideration for builders working in humid or mixed climates.

Non-Perforated Moisture Barrier Construction

The non-perforated design eliminates the pin-hole failure points common in mechanically perforated wraps, providing continuous moisture resistance across the entire face of the barrier. This makes it especially reliable behind claddings that may allow bulk water infiltration through joints or fastener penetrations.

Wind and Tear Resistance

The durable coated non-woven construction resists tearing during installation and under wind-driven conditions prior to cladding application. This reduces waste from installation damage and maintains barrier integrity on job sites where material is exposed between framing and cladding stages.

All Climate Zone and All Cladding Compatibility

Approved for use in all climate zones and behind all cladding systems — including wood siding, fiber cement, stucco, and manufactured cladding — the Elite WRB eliminates the need for job-specific product selection. One SKU covers the full range of residential applications a contractor encounters.

Code Compliance — ICC-ES AC38 and UL CCRR-0520

Meets and exceeds ICC acceptance criteria for water resistive barriers (AC38) and conforms to UL STD CCRR-0520 and CSA STD, with Control No. 5026846. This documentation simplifies inspections and supports specifications requiring listed products, reducing the risk of job-site delays tied to product approval.

10-Year Product Limited Warranty

Backed by a 10-year product-only limited warranty against manufacturing defects when installed per Tamlyn installation guidelines. This provides builders and contractors with documented product backing that can be communicated to owners and included in project closeout documentation.

Economical Coverage — 1,125 SF Per Roll

At 9 ft wide and 125 ft long, each roll delivers 1,125 square feet of coverage, reducing the number of horizontal seams on typical two-story applications and minimizing lap waste compared to narrower rolls. The 22-lb roll weight keeps handling practical for two-person installation crews.

Common Applications

Residential New Construction

Primary application as a drainage plane and air barrier behind all exterior cladding on wood-framed residential structures, compliant with IRC and IBC moisture management requirements.

Fiber Cement Siding Installations

Compatible for use directly behind fiber cement lap and panel siding, providing the moisture management layer required by most fiber cement manufacturers and building codes.

Wood and Engineered Wood Siding

Functions as the required WRB layer beneath wood lap, shiplap, and engineered wood siding products, where vapor permeability is essential to allow the assembly to dry inward or outward depending on climate.

Stucco and EIFS Substrates

Serves as the code-required water resistive barrier layer in stucco wall systems, providing a continuous drainage plane behind the scratch coat or insulation board.

Manufactured and Composite Cladding

Suitable behind vinyl, aluminum, and composite cladding systems where an underlying WRB is required for air sealing and moisture protection per building code.

Residential Remodel and Re-Cladding

Can be installed over existing sheathing during re-cladding projects to upgrade or restore the WRB layer without complete sheathing replacement, provided the substrate is sound and smooth.

Application Instructions

Surface Preparation

1. Ensure sheathing is dry, structurally sound, and free of protrusions that could puncture or prevent full contact with the barrier.
2. Install all rough openings, windows, and doors with appropriate flashing (XtremeFlashing Tape or approved equivalent) prior to WRB installation.

Installation

1. Install TamlynWrap Elite WRB in SHINGLE FASHION, starting at the base of the wall and working upward so that each successive course overlaps the course below.
2. Maintain a minimum 6-inch overlap on all horizontal seams.
3. Maintain a minimum 6-inch overlap on all vertical seams.
4. At any corners, maintain a minimum 12-inch vertical overlap.
5. Integrate the WRB with window, door, and penetration flashings to promote positive mechanical drainage throughout the wall assembly.
6. Attach using cap fasteners throughout — cap fasteners are required per installation guidelines and are a warranty condition.

Sealing

1. Tape all seams with Tamlyn Elite Tape or an approved compatible seam tape per project requirements.
2. Seal all penetrations (utility, fasteners, mechanical) with XtremeSealant, Tamlyn BrunnoSeal, or approved compatible sealant.

Cladding Application

1. Proceed with cladding installation promptly after WRB installation; refer to product UV exposure limits for maximum allowable exposure time before covering.
2. Follow all cladding manufacturer requirements for fastening through the WRB into substrate sheathing.

Technical Specifications

Frequently Asked Questions

Q: Can TamlynWrap Elite WRB be used in all climate zones?
A: Yes. The product's vapor permeability (perm rating of 20) and moisture resistance make it suitable for use in all climate zones as defined by the IRC and IECC, including mixed-humid, hot-humid, cold, and marine climates.

Q: What fasteners are required for installation?
A: Cap fasteners are required throughout for attachment to the sheathing. Standard staples or nails without caps are not acceptable per Tamlyn installation guidelines and will void the warranty.

Q: What tape should be used for seams and laps?
A: Tamlyn recommends Tamlyn Elite Tape for seaming TamlynWrap Elite WRB. XtremeFlashing Tape is recommended for flashing penetrations and openings.

Q: Is TamlynWrap Elite WRB code-listed?
A: Yes. It conforms to UL STD CCRR-0520 (Control No. 5026846), is certified to CSA STD, and meets or exceeds ICC-ES acceptance criteria AC38 for water resistive barriers — the primary acceptance criteria used by building officials for WRB products.

Q: What is the required overlap at corners?
A: All horizontal and vertical seams require a minimum 6-inch overlap. At any corners, a minimum 12-inch vertical overlap is required. The product must be installed shingle fashion to promote positive drainage.

Q: How long can TamlynWrap Elite WRB be exposed before cladding is applied?
A: Maximum UV exposure time is specified in the product's installation guidelines and TDS. Exceeding the rated exposure period can void the warranty. Refer to the Technical Data Sheet
