Open Cell Polyurethane Backer Rod for Hot and Cold Sealant Applications

Basic Use:  Tundra Foam is an ideal non-gassing backup material which is inserted into a construction and pavement joints to:

• Control sealant and caulking depth
• Create a backstop to allow proper sealant tooling and configuration
• Allow proper sealant airing and yield a proper bond breaker.

It is ideal for non-uniform joint sizes.

Compatibility: Tundra Foam is basically an inert material and therefore compatible both physically and chemically with virtually all known hot pour and cold applied sealants including silicon and rubber asphalt.

Specific Uses:  Commonly used in expansion and contraction joints, window glazing, curtain wall construction partitions, precast assemblies and copings, parking decks, bridge construction, etc.

Composition and Materials:  Tundra Foam is a fabricated round, open cell, polyurethane foam material. It is highly flexible and compressible for easy application. It is available in a black (ebony) colour and in a wide variety of sizes each capable of fitting a number of differing joint sizes.

Ebony (Black) Color: An ideal neutral rod color under most sealants, it is excellent for window glazing applications where Backer Rod is sometimes visible.
