Le ruban architectural CRL en butyle est un ruban extrudé, pré-formé, enroulé sur papier intercalaire et s’utilise pour le verre d’architecture. Sa formulation en caoutchouc de butyle est conçue pour créer un joint durable, flexible et imperméable aux intempéries entre deux surfaces soumises aux forces normales de contraction/expansion et d'accumulation du vent. Il peut servir en tant que joint d’espacement extérieur et comme scellant pour vitres principales lors de la pose du verre dans les cadres de fenêtre, ou pour sceller d’autres surfaces architecturales telles que les joints de métal à métal, le bois au verre, ou le métal au plastique.

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.
