introduced its first commercial interior surface coating for
glass, SunGuard IS 20. The new product brings the U-value
performance of double-glazed, insulating glass units closer to
that of triple glazed, and bumps up the performance of triple-
glazed IGUs.  If triple glaze is specified, SunGuard IS 20 can

effectiveness of Guardian’s advanced architectural glass when
combined with any SunGuard coating. For example, when SunGuard
IS 20 is teamed with Guardian SNX 62/27, the resulting product

double-glazed unit, according to Guardian representatives.
