A Proven History...
Alsco-Cardinal searched extensively for a manufacturing partner who could work
with us to develop the trademarked Cardinal High Altitude Window® Series that
will truly meet the needs of Colorado homeowners. After visiting and interviewing
major manufacturers we selected Amerimax, a $750 million a year company.
Together, Amerimax and Alsco-Cardinal developed the High Altitude Window®
Series and the Insulated Super Glass® Package, built in Colorado FOR Colorado!
