NOTES:

  • The performance values shown are nominal for the center of glass (no spacer or framing) and subject to variations due to manufacturing tolerances
  • The performance data are based on a standard 1″ insulating glass unit with ¼″ (6mm) outboard lite, a ½″ air space and ¼″ (6mm) inboard lite. Each laminated lite is 9/16″ thick (two ¼″ plies with 060″ PVB interlayer).
  • Guardian performance data are calculated in accordance with the LBNL Window 5.2 computer analysis using an air mass of 1.5.
  • The outboard and / or inboard lite may require heat strengthening or tempering to resist potential thermal stresses. Please contact Guardian for assistance.
  • A slight shift in visible light reflectance or transmission may be noticed after heat-treatment.
  • When SunGuard coatings are laminated facing the PVB, there will be a noticeable color change. Guardian recommends a full-size mock-up be approved.
  • Guardian reserves the right to change product performance characteristics without notice or obligation.
