Vanceva® color interlayers offer certain high-performance safety characteristics, useful in demanding applications such as vertical, sloped and overhead glazing. The tough plastic interlayer resists penetration from accidental impact and, unlike ordinary glass, won’t shatter into dangerous fragments if broken. Vanceva color PVB interlayer is sold at a minimum of 15 gauge (0.38 mm, 0.015 in). Laminated glazing made with Vanceva interlayer, when used in the proper thickness can meet the federally mandates safety glass requirements of CPSC and is also able to meet the various requirements outlined in ANSI and ASTM standards related to laminated glass. Below are some common applications where Vanceva color interlayer is commonly used.
Vertical Safety Glazing: Typical applications requiring safety glazing include entrance doors, storm doors, patio-type sliding doors, shower and bath enclosures, sidelights and fixed glazed panels. These federal requirements for safety glazing are outlined in CPSC CFR 16 Part 1201 and the voluntary standard ANSI Z97.1 provides test and specification information for safety glazing used in areas not addressed by the CPSC document.
Laminated glass made with Vanceva PVB color interlayer breaks safely. While the glass may crack under impact, it typically remains integral. Glass splinters and sharp fragments tend to adhere to the plastic interlayer. This is in contrast to annealed glass, which fractures easily into long, sharp-edged shards, or tempered glass which breaks into pieces that may reduce cutting or piercing injuries, but still has the predominance to vacate the frame once broken.
