Translucent 100%<br />
Spandrel Opaque 100%<br />
**Not available for interior applications and not available with coatings on the same surface. Also, when translucent frit is used as full coverage, inherent characteristics<br />
may make this product unsuitable for vision areas. These characteristics include slight variations in color and uniformity, pinholes or streaks.<br />
When considering translucent frits for spandrel applications note that these areas may be prone to condensation formation on interior<br />
glass surfaces. Over time, this may result in a visible film formation. Therefore, consideration must be given to the suitability of these<br />
products in spandrel applications. For these applications, the translucent frit may only be applied to non-exposed surfaces.<br />
See silk-screen inspection guidelines and manufacturing tolerances on page 124 for additional information.<br />
MOIRé PATTERN<br />
Moiré is an optical phenomenon that may present itself as a “wavy, rippled or circular” pattern under certain conditions. Moiré patterns<br />
can be created whenever one semi-transparent object with a repetitive pattern is placed over another. The moiré pattern is not a glass<br />
defect, but created when the images do not align. For additional information, please review Viracon’s Moiré Pattern Tech Talk on our<br />
