Original BackerBead®
Combination PVC Casing Bead with built-in closed cell backer rod
Eliminates the need to install a backer rod separately, as the product features a factory-applied backer rod that is affixed to the vinyl casing bead and set to the exact height and depth.
Quick Actions:
This allows the installer to create a “gap” on the wall without the hassle of aligning it in the field, thereby saving time and materials.
Features / Benefits:
- Combination Bead - Reduces steps in the field installation of casing bead and separate backer rod. Ensures backer rod is installed around all door and window openings.
- Improved Quality - 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.
- Separation of Dissimilar Materials - Properly terminates stucco and mortar at window and door frames.
- Sealant Compatibility - Closed-cell backer rod compatible with elastomeric and other cold-applied sealants.

- 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, curtain walls, skylights, 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.
