CRL GT206 Black 1/8" x 1/2" Butyl Glazing Tape

CRL GT206 Black 1/8" x 1/2" Butyl Glazing Tape

C.R. Laurence GT206 Black 1/8" x 1/2" Butyl Architectural Glazing Tape is expertly designed to provide a robust and flexible weather seal suitable for various architectural applications. Crafted from a high-quality butyl rubber formulation, this tape boasts exceptional age and weather resistance, ensuring longevity even under extreme conditions. With a 100% solids content and zero VOCs, it meets AAMA certification standards, making it a reliable choice for building professionals. This versatile tape serves as an exterior primary spacing and glazing seal, effectively bonding glass to window sashes while also accommodating connections between metal, wood, and plastic surfaces. Its thickness allows for approximately 10% compression upon installation, facilitating optimal surface alignment and joint movement of ±15%. The GT206 tape performs effectively within a temperature range of 20°F to 120°F for application and withstands service temperatures as low as -40°F and up to 190°F. With a minimum service life of 20 years, it is an investment in durability. Available in both gray and black, this tape is provided on a convenient 25-foot roll, making it easy to use in various projects. For best results, adhere to recommended good glazing practices, ensuring a clean and well-prepped surface prior to installation.

Black 1/8" x 1/2" Butyl Architectural Glazing Tape

• Age and Weather Resistant Butyl Rubber Formula
• 100% Solids Content
• Meets AAMA Certification
• Used as an Exterior Primary Spacing and Glazing Seal
• Available in Gray and Black

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.

Good Glazing Practices
The following "Good Glazing Practices" are recommended when using CRL Glazing Tapes. Surfaces to be adhered should be free of frost or standing water, brushed clean, solvent washed (MEK, Toluene or Naptha) and wiped dry. At installation, positive contact and approximately 10 percent compression is recommended to fully marry surfaces to be joined. Glazing tapes kept under compression with clips or wedges provide the best seals.

Always use setting blocks (80 durometer Shore "A" hardness) placed at the sill quarter points. Spacing shims are recommended to accommodate wind loading when glass lite is over 100" (50 durometer Shore "A" hardness). Tape placement on the sill rabbet is not to be below the sight line unless a cap bead is specified, then tape is placed 3/16" (4.8 mm) below the sight line to allow for the cap bead. Do not overlap tape to join; always butt ends without stretching. To keep the tape surface clean, leave the release paper in place until ready-to-set the glass.


Product Warning:

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.
