Achieving a truly watertight and airtight building envelope is critical for energy efficiency, occupant comfort, and the long-term durability of any structure. The Protecto BT25XL Window and Door Flashing Tape, offered by A1A Wholesale Supply, is a high-performance solution specifically designed to create a positive air/vapor barrier around window and door installations.

BT25XL is a cold-applied, self-adhering membrane composed of a tough, cross-laminated High-Density Polyethylene (HDPE) surface. This durable surface is coated on one side with a proprietary blend of polymer-modified asphalt adhesive. This advanced adhesive blend ensures strong adhesion to most construction surfaces, including OSB, aluminum, vinyl, plywood, stucco, fiber-cement, glass-faced gypsum, and ICF foam.

A key feature for ensuring watertight integrity is its ability to seal around nails and staples, effectively preventing water penetration through fastener points. The tape boasts excellent self-sealability, passing water penetration resistance tests both immediately and after thermal cycling.

Key Features and Benefits for Contractors:

• Superior Waterproofing: Designed as a complete waterproof self-adhered flashing, creating a positive air/vapor barrier.
• High Performance Adhesive: Proprietary blend of polymer modified asphalt adhesive ensures strong, consistent bonds.
• Seals Fasteners: Effectively seals around nails and staples to prevent water intrusion.
• Excellent Adhesion: Compatible with and adheres to most common construction surfaces. Passes 90° Peel adhesion tests on multiple substrates, even after accelerated aging, elevated temperatures, thermal cycling, and water immersion.
• Durability: Features a 25-mil thickness and a 120-day UV exposure rating, providing ample time for exterior finishing.
• Meets Industry Standards: Meets or exceeds AAMA 711-13 and CSA A440.4-07 requirements for self-adhered window and door flashing.
• Wide Temperature Range: Suitable for installation in temperatures from 40°F to 120°F (5°C to 48°C) and can withstand in-service temperatures from -45°F to 240°F (-42°C to 116°C).
• Low Permeance: Extremely low permeance at 0.01 perms maximum, contributing to its effectiveness as an air/vapor barrier.
• Safe for Windows: Safe for use on most wood, wood clad, aluminum, fiberglass, and vinyl windows and doors (avoiding softwoods with high resin concentration).

Applications:

• Window and Door Installations: Used as a complete waterproof self-adhered flashing to create positive air/vapor barriers.
• Sealing Joints: Effective for sealing joints in exterior sheathing.
• Sealing Penetrations: Can be used for sealing penetrations in roof and wall systems.
• Repair and Air Sealing: General use for air sealing and moisture protection on various construction surfaces.

Installation Considerations:

• Preparation: All surfaces must be clean, dry, and free of foreign materials, gaps, sharp edges, and protrusions. Metal surfaces may require solvent wiping or abrasion.
• Priming: A primer should be used if the surface is DensGlass Gold, OSB, concrete block, masonry, fiber board sheathing, exterior gypsum, saturated felt type building wrap, damp, or below 40°F (5°C). Some housewrap materials may also require primer; field testing for adhesion is recommended.
• Application: Apply the first piece to the rough opening sill, overlapping the housewrap. Use a hand roller to smooth out wrinkles, air bubbles, or creases. Apply vertical pieces over nailing flanges and onto sheathing, followed by the final top piece overlapping the vertical sides. Housewrap or building paper should be applied over the BT25XL at the sides and head of the window, sealed with housewrap tape.
• Cold Weather: For cold weather applications (below 40°F/5°C), products should be kept warm (50°F to 90°F / 10°C to 32°C) for at least 24 hours prior to installation. Primer may be needed if adhesion is marginal.
• Limitations: Not recommended for use on highly plasticized nailing flanges or drip caps (consult window manufacturer). Avoid contact with solvent-based sealants, uncured (wet) sealants/adhesives, PVC, TPO, and EPDM type materials. Not recommended for roofing applications or in high-temperature applications exceeding 240°F (116°C).

Warranty & Storage: Protecto BT25XL is covered by the Protecto Wrap Standard 10 Year Limited Warranty. For optimum initial adhesion, use within one year from the date of manufacture. Store in original, unopened containers at ambient temperatures between 40°F to 90°F (5°C to 32°C) in a dry area, out of direct sunlight.
