Denver Foam® is an open cell polyurethane backer rod serving as a backing for elastomeric and other applied caulking sealants.
Denver Foam® controls the amount of sealant required and depth of the installation. Also, it forms the correct hour glass shape of sealant, assuring the contractor and owner the best adhesion and cohesion configuration possible.
Composition and Materials:
Denver Foam® is continuous lengths of flexible, round, fabricated open cell polyurethane. It is yellow in color and available in a wide range of diameters.
Limitations:
Whatever restriction the Sealant Manufacturer places on his product, the same will apply to Denver Foam®. For use in expansion/construction joints in concrete and precast concrete walls, floors, partitions, bridge construction, parking decks, curtain walls, glazing, log home construction, highway construction, and pavement maintenance.
New highway construction and pavement maintenance can be installed with Denver Foam®. Denver Foam® can withstand the temperature of hot pour sealant in maintenance work. Denver Foam® is an open cell backer rod allowing air to reach both sides of sealant, assuring you the required complete cure.
Most of these joints are saw cut and approximately 3/8" wide. The design depth keeps the sealant below traffic contact and vacuum lift created by fast moving vehicles.
Denver Foam® is chemically inert and resists oil, gasoline and most solvents. The material is odorless and will not stain. The open cell construction eliminates the out-gassing and cold flow problem associated with closed cell polyethylene Backer Rods. The sealant also has the benefits of a 2-sided cure.
