Dealing with complex and irregular penetrations in building envelopes can be a significant challenge for achieving a continuous air and water seal. The Protecto Form Flash I™ Conformable Flashing Tape, offered by A1A Wholesale Supply, provides a highly adaptable solution to these difficult areas, ensuring a tight and durable seal.
This product is a 50-mil thick, cold-applied, self-adhering membrane with a black color. It’s uniquely designed with a conformable and stretchable film on one side, paired with a layer of polymer-modified asphalt adhesive. This combination allows Form Flash I to expand and conform to irregular shapes, eliminating the need for complex cutting and patching.
Form Flash I creates a positive air/vapor barrier, contributing to the overall energy efficiency and moisture management of a structure. It also reliably seals around nails and staples, preventing water intrusion at fastener points. The tape has a 30-day exposure rating, providing flexibility during construction.
Key Features and Benefits for Contractors:
- Conformable to Irregular Shapes: The stretchable film allows the tape to conform to complex contours without cutting and patching.
- Positive Air/Vapor Barrier: Helps prevent air and moisture infiltration, improving energy efficiency.
- Seals Fasteners: Effectively seals around nails and staples.
- Versatile Adhesion: Compatible with and adheres to most construction surfaces.
- Durable: A 50-mil thickness provides robust protection.
- Moderate UV Exposure: Can be exposed for up to 30 days.
- Wide Operating Temperature: Has an in-service temperature range of -45°F to 240°F (-42°C to 116°C).
- Low Temperature Flexibility: No cracks or delamination at -20°F (-29°C).
Applications:
- Sealing Penetrations: Used to seal around various penetrations on the exterior of a building, including:
- Cable lines
- Electrical outlets
- Gas lines
- Hose bibs
- Dryer vents
- Air exchange vents
- Pipe penetrations
- Interior Applications: Can be used for water/gas pipe penetrations under sink cabinets, basement walls, and attic spaces.
- Insect/Rodent Barrier: Can also be used as an insect/rodent barrier.
Installation Considerations:
- Surface Preparation: Surfaces should be clean, dry, and free of dirt and other foreign materials.
- Priming: For cold weather applications or if adhesion is marginal, a primer may be necessary. Products should be stored in a warm, dry area (50°F to 90°F / 10°C to 32°C) for at least 24 hours prior to installation in cold weather.
- Application Method: For sealing around boxes or outlets, position the tape in the center of the opening and push it into the opening to adhere to the interior.
- Limitations:
- Not recommended for use in high-temperature applications exceeding 240°F.
- Not for long-term UV exposure (beyond 30 days); must be covered by exterior siding, housewrap, or equivalent.
- Should not come into contact with solvent-based products, polysulfides, highly plasticized PVC materials, or high concentrations of resins (pitch).
- Not recommended for roofing applications or in contact with PVC, TPO, and EPDM roofing materials.
- Do not apply over uncured (wet) sealants or adhesives.
