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.

Features

• 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.

1/4” Tear-away strip provides a clean, stucco-free caulk gap. A clean 1/4” x 1/4” caulk gap assures the most efficient caulk seal for optimal moisture protection.
