BackerBead® with Short Flange

Casing Bead with factory applied blue backer rod

BackerBead® with Short Flange is perfect for situations where the standard 1-3/4" flange size is too large for the application. Factory-applied blue backer rod with preset width and depth to ensure proper caulk gap for sealant application. When the gap is properly caulked, the blue backer rod will no longer be visible.

Description

Easy to install in tight areas such as recessed doors and windows, providing added moisture protection and a clean finish. A labor saving and quality control product for use at exterior openings in wet wall stucco applications.

To properly assemble a wall cladding system using stucco or manufactured stone veneer, the best practice is to maintain a "gap" around door and window openings and install a backer rod with compatible sealant in order to keep moisture out. The use of BackerBead® ensures that the correct caulk gap will be created around all door and window openings on exterior walls. The gap is predetermined by the factory-applied, closed-cell backer rod that is properly aligned and adhered to the vinyl casing bead. This approach eliminates the need to install the backer rod separately, saving time and ensuring a consistent, normal gap width and depth of 1/4" x 1/4". When installed and caulked properly, BackerBead® provides added protection from water penetration.

Vinyl is impervious to corrosion when coated in veneer plaster, wet joint compounds, or when placed in contact with steel or aluminum frames and resists impacts, dents, and damage during construction. No priming is required to add paint to vinyl products due to its paint adhesion properties. Vinyl has low electrical and thermal conductivity and is considered an excellent insulator, as well as being self-extinguishing and offering better resistance to burning than many other common building materials. Additionally, vinyl has a lower cost than equivalent products manufactured from zinc or aluminum, for use when the highest levels of corrosion resistance are required.

Installation

Installation:

Prior to placing the BackerBead, clean all surfaces to receive the bead and remove any oil and moisture. Refer to sealant manufacturer’s recommendations.

Resources

ASTM & Code Standards:

  • Vinyl Material: Complies with ASTM D1784 and ASTM C1063, Table 1, PVC for exterior use.
  • Backer Rod: Closed cell material per ASTM C1330, square, flexible continuous lengths of extruded polyethylene foam used as a backing material.
  • Passed ASTM E331 - Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference.  This ASTM performance covers the determination of the resistance of exterior windows and doors to water penetration when water is applied to the outdoor face and exposed edges simultaneously with a uniform static air pressure at the outdoor face higher than the pressure at the indoor face.   Stucco was tested in this condition both with the BackerBead® and caulking, vs. no bead and caulked gap, which did not pass the E331 test.  Test results are available upon request.
  • SDS & Product Certification Information
  • Backer Rod - Closed-cell material per ASTM C1330, square, flexible, continuous lengths of extruded polyethylene foam used as backing material. Meets or exceeds the requirements of ASTM C1016 Standard Test Method for Determination of Water Absorption of Sealant Backing (Joint Filler) Material.
  • BackerBead components are chemically inert and virtually dust-free.
