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.
