• Sealant backer rod is an extruded round, grey, closed-cell low-density polyethylene foam with a skin-like outer texture.
• It is an ideal non-absorbent, compressible, back-up material inserted into a joint to control sealant tooling, to allow proper sealant wetting of the joint surfaces, & to yield proper bond breaker between the backup material & the sealant.
• Commonly used in glazing operations, window & door applications, expansion joints, curtain wall joints, partitions, log construction, pavement joints & repairs, precast units, & copings.
