Armacell – ITP Tundra® Polyurethane Foam Backer Rod

Tundra® Foam is an ideal non-gassing backup material that is inserted into construction and pavement joints to control sealant and caulking depth, create a backstop to allow proper sealant tooling and configuration and to allow proper sealant airing and yield a proper bond breaker. Also commonly used in expansion and contraction joints, window glazing, curtain wall construction partitions, precast assemblies and copings, parking decks and bridge construction.
