CRL GT104 Black 1/16" x 3/8" Butyl Glazing Tape

C.R. Laurence GT104 Black 1/16" x 3/8" Butyl Architectural Glazing Tape is engineered for superior performance in glazing applications. Utilizing a specialized butyl rubber formula, this tape is designed to withstand the rigors of age and weather, ensuring a durable seal that can adapt to normal expansion and contraction, as well as wind loading forces. With a 100% solids content, it meets stringent AAMA certification standards, making it an ideal choice for exterior primary spacing and glazing seals. This versatile tape is perfect for glazing glass into window sashes and sealing various architectural surfaces, including metal to metal joints, wood to glass, and metal to plastic connections. The product's thickness allows for approximately 10% compression during installation, optimizing surface alignment for a tight seal. Available in both gray and black, the GT104 measures 1/16 inch thick and 3/8 inch wide, with a roll length of 50 feet. It operates effectively in a wide temperature range, from 20°F to 120°F during application and can service temperatures as low as -40°F and as high as 190°F. For best results, follow recommended installation practices to ensure maximum adhesion and performance.

Black 1/16" x 3/8" 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.
