All CollidEscape offerings on this site are compliant with the performance
standards as prescribed for the City of New York;  the performance is
based on a TF rating ("Threat Factor") with the lower the number
signifying  better performance; all solutions offered by CollidEscape
comply with NYC ordinance (see here) and even with custom options,
no offerings on our site exceed TF30 (CollidEcape's TF1 is the best-rated offering on the market today -on  the standard 10-year rated, outdoor applied CollidEscape CE Guaranteed(tm) - White bird collision prevention
film (screening)).

All solutions recommended by CollidEscape adhere to the 2" x 2"  standard rule accounting for different bird sizes and species but are also flexible enough to execute the more aggressive 2x2 standard indicator in New York. To gain an 'Acceptable' Avoidance Index Score from American Bird Conservancy, the 2″ x 4″ rule: Two inches or less of horizontal space or four inches or less of vertical space between pattern markings must be maintained, but a 2"x2" pattern is preferable for even better performance under all glass installation conditions.

All patterns, spaced no greater than 2" apart, even if in a staggered pattern, have been independently field tested to perform, with a threat factor equivalent to between 3-20, depending on options and configurations, as well as all proposed pending modifications.
