Product details:
CRL Butyl Architectural Glazing Tape is an extruded, preformed tape furnished on release paper rolls. Based on a butyl rubber formulation with proven age and weather resistant properties, it is designed to create a long lasting, flexible weather seal between two surfaces that will be subjected to normal expansion/contraction and wind loading forces. It is used as an exterior primary spacing and glazing seal when glazing glass into a window sash; also used to seal other architectural surfaces such as metal to metal joints, wood to glass, metal to plastic, etc. The thickness is designed to be compressed approximately 10 percent at installation to accommodate surface alignments. Typical Properties Base Polymer Butyl rubber (polyisobutylene); SolidsContent 100% solids (no asbestos); Cure Time fully cured before application; Hardness 20 durometer Shore "A" @ 77 (25C); Temperature Range Application 20F (-7C) to 120F (49C); Service -40F (-40C) to 190F (88C); VOCContent 0%; Joint Movement 15% of joint width;Service Life 20 year minimum.Limitations For applications above two floors use a spacer, shim, or a structural cap bead (such as silicone) to prevent over compression or use CRL 100+ Load Bearing Glazing Tape.Applicable Standards AAMA 804.3, 806.3, and 807.3.
