Creating an effective building envelope is paramount for managing internal environments, preventing moisture-related issues, and optimizing energy consumption. The Protecto PW 100/40 Non-Permeable Self-Adhered Air/Vapor Barrier & Thru-Wall Flashing, offered by A1A Wholesale Supply, provides a high-performance solution for comprehensive protection against air, vapor, and moisture intrusion across various building applications.

PW 100/40 is a cold-applied, self-adhering membrane with a substantial 40 mil thickness. It is composed of a tough, cross-laminated High-Density Polyethylene (HDPE) facer coated with a layer of polymer-modified asphalt adhesive. This advanced adhesive ensures strong, consistent bonds and provides excellent adhesion to most construction surfaces.

A key performance feature is its ability to seal around nails and staples, preventing water penetration through fastener points. Its extremely low water vapor transmission rate of 0.01 perms max (0.009 Perms) solidifies its role as a highly effective non-permeable air and vapor barrier. This helps control moisture diffusion and air leakage through the wall assembly.

Key Features and Benefits for Contractors:

• Comprehensive Barrier: Forms a non-permeable air and vapor barrier, crucial for building performance and energy efficiency.
• High Performance Adhesive: Polymer-modified asphalt adhesive provides strong, reliable adhesion to most construction surfaces.
• Seals Fasteners: Effectively seals around nails and staples, maintaining membrane integrity.
• Durable: Boasts a 40-mil thickness and a 120-day exposure rating, allowing flexibility in construction scheduling.
• Temperature Versatility: 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). It also exhibits excellent cold temperature flexibility, passing tests at -25°F (-32°C).
• Code Compliant: NFPA 285 Compliant in assemblies with various insulations.
• Puncture Resistance: Offers excellent puncture resistance at 57.2 lbs.
• Safe for Windows: Safe for use on most wood (avoiding softwoods with high resin concentration), wood clad, aluminum, fiberglass, and vinyl windows and doors.

Applications:

• Full Wall Building Envelope: Ideal as a full wall non-permeable building envelope application.
• Window and Door Flashing: Functions as a self-adhered flashing for window and door installations where a 40 mil product is required.
• Sealing Joints: Effective for sealing joints in exterior sheathing.
• Sealing Penetrations: Used for sealing penetrations in wall systems.
• Thru-Wall Flashing: Serves as a reliable thru-wall flashing component.
• Below-Grade Applications: Can be used below-grade on ICF foundations.

Installation Considerations:

• Preparation: All surfaces must be clean, dry, and free of foreign materials, gaps, sharp edges, and protrusions. Metal surfaces may require cleaning or abrasion.
• Priming: A primer should be used if the surface is DensGlass Gold®, OSB, concrete block (CMU), masonry, fiber board sheathing, exterior gypsum, saturated felt type building wrap, or if the surface cannot be cleaned to a like-new condition, is damp, or below 40°F (7°C). Field testing for adhesion is recommended. For ICF, only Universal Water Based Primer should be used if adhesion is marginal.
• Full Wall Application: Can be installed horizontally or vertically, forming water-shedding laps with a minimum of 2″ side laps and 4″ end laps. All membrane terminations should be sealed with JS160-H Mastic or Protecto 25XL Sealant.
• Window Installation: Apply to the rough opening sill, overlapping housewrap/building paper. Roll firmly to remove wrinkles/air bubbles. Apply vertical pieces over nailing flanges, then the final top piece overlapping vertical sides. Housewrap/building paper should overlap the sides and head, sealed with housewrap tape.
• Cold Weather: Products should be stored in a warm, dry area between 40°F to 90°F (5°C to 32°C) and kept warm for at least 24 hours prior to installation. Priming is recommended when temperatures are below 40°F (5°C).
• Limitations: Not recommended for use on highly plasticized nailing flanges, near solvent-based sealants, over uncured (wet) sealants, or in contact with PVC and EPDM roof coverings. Not for roofing applications or in high temperature applications exceeding 240°F (116°C).

Warranty & Storage: PW 100/40 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. Do not double stack pallets. Open rolls should be stored airtight.
