Standard Closed Cell Backer Rod
The Standard Closed Cell Backer Rod is a versatile and essential component for construction and joint sealing projects. Made from durable, closed-cell, low-density polyethylene foam with a density of 1.5 lbs/cu. ft. and an R-value of 2.2, this backer rod is designed to provide a flexible, compressible, and non-absorbent backing for joints. Its primary function is to control the depth of sealant, ensuring proper application and maximizing the longevity of your seals.
With its skin-like outer texture, the Standard Closed Cell Backer Rod offers superior bonding with a wide range of cold-applied sealants, including butyl, polysulfide, acrylic, polyurethane, and silicone. This makes it ideal for applications such as glazing operations, window and door installations, expansion joints, curtain wall joints, and partitions. It is also highly effective in log construction and pavement joints, where precise joint control is critical.
The rod’s dark grey color ensures a professional appearance in exposed installations, while its compressibility and lightweight design allow for easy handling and installation. It serves as a temporary joint seal and a backstop for tooling, promoting even application of sealants. This product meets several ASTM standards, ensuring reliability and performance in demanding conditions.
