Combination PVC Casing Bead with built-in closed cell backer rod
Factory-applied, closed-cell backer rod provides a sealed separation gap 1/4" wide where stucco abuts dissimilar materials such as the perimeter of window and door openings per ASTM C1063.
ClarkDietrich BackerBead® 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. 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. When the gap is properly caulked, the blue backer rod will no longer be visible. E-Flange profile provides 80% more stucco embedment than traditional flat flange profiles.
Closed-cell backer rod compatible with elastomeric and other cold-applied sealants. The factory applied backer rod is adhered with setback of 1/4" from the leading edge of the ground on BackerBead casing bead products, unless noted. BackerBead also available with a solid 1-3/4" flange upon request. Backer Rod also available in white upon request for clear sealant applications.
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.
