Product description

KOOL-ROD is a closed cell, polyethylene, flexible, rope-like foam joint backing material.
This material is virtually non-absorbent and chemically inert to most solvents. KOOL-ROD will not stain or adhere to sealant materials. It is fully compatible with acrylic, butyl, polyurethane, polysulfide, silicone, and most other cold-applied sealant compounds.
KOOL-ROD is specifically designed as a compressible backing material to be used in conjunction with a wide variety of cold-applied joint sealants.

KOOL-ROD is highly adaptable for both vertical and horizontal applications. It is commonly used in glazing operations, copings, between precast panels, and around door and window perimeters. It provides the perfect backing for all types of construction, expansion, isolation, control, and pavement joints.
