The Compression Seal Integrated Sealant (CSIS) is a factory cured strip of silicone sealant adhered to a rectangle polyurethane backer. The polyurethane backer is wider than the joint opening and the silicone is of a lesser width than the joint opening. The backer is compressed and placed into the joint, thus holding the cured silicone in a vertical position and leaving a recess on either side of the cured silicone and parallel substrate. A wet silicone sealant is caulked and tooled into the recess bridging the cured silicone and the interface of the parallel substrate.
The CSIS-Series foam seal is designed for sealing vertical expansion joint openings that measure 2" or greater.
Features and Benefits:
♦ Long-lasting life due to not being affected by ozone or ultraviolet rays. Has excellent stability in regards to movement capability and modules
♦ Movement capability of +/- 50%
♦ Aesthetics allow for larger joint design which reduces stress on the bond line, increasing the chances of successful sealant installation
♦ Primer-less adhesion to a variety of substrates including masonry and concrete. No staining
♦ Easy to install. No anchoring systems, mechanical fasteners, cutting of substrates or waiting for expansion to accrue
♦ Caulking the reveals on each of the cured sealants makes it necessary to fill to full depth - no "cheating" on the amount of sealant placed
♦ Available in 16 standard colors. Custom colors available upon request
