Soft-Type Backer Rod

Basic Use:  ITP Soft Type Backer Rod is a soft, pliable, non-gassing backup material inserted into an expansion or contraction joint to:

• Control sealant depth
• Create a backstop to allow proper sealant tooling
• Ensure sealant adhesion to joint surfaces only
• Yield a proper break between backup material and sealant.

It can also be used as a temporary joint seal.

Compatibility: ITP Soft Type Backer Rod is virtually an inert composition and therefore compatible with all known cold applied sealants including butyl, polysulfide, acrylic, polyurethane and silicone.

Specific Uses:  Particularly suited for specialty applications where Standard Backer Rods are not appropriate. Ideal in irregular joint applications particularly where self leveling, flowable sealants are employed. Also recommended with sealants where bubbling concerns are critical. May also be used in place of most standard backer rod applications.

Composition and Materials:  ITP Soft Type Backer Rod Insualation is an extruded round, dust free, polyethylene based foam material with a skin-like outer texture. It is highly flexible, pliable and compressible for easy installation. It is available in a medium grey for easy identification and several other colors on a custom basis.
