    Quantity:

    Open Cell Backer Rod is ideal for non-uniform joint sizes, and is commonly used in expansion and contraction joints, window glazing, curtain wall construction partitions, precast assemblies and copings, parking decks, bridge construction, and more.

    Open Cell Backer Rod, an inert material, is compatible physically and chemically with virtually all known hot-pour and cold applied sealants including silicone and asphalt.

    Installation:
    The joint depth must be great enough to allow for the proper installation of the Open Cell Backer Rod and the hot or cold sealant or caulking material. Joint walls must be smooth and even as possible and be free of any loose residues or foreign materials. Joints should also be dry and frost-free. With a
    convenient tool or by hand, insert Open Cell Backer Rod into joint at a level recommended by the sealant manufacturer. Cold applied sealants generally recommend that the depth of the joint after the backer rod is installed be one half the width. In hot pour applications, it is generally recommended the depth of the joint be a 1:1 ratio in terms of Backer Rod to sealant.
