Gold Label Program

CrystaLok glass block windows produced in Pittsburgh have just become part of the AAMA Gold Label Program.

Standard Series CrystaLok windows were tested under AAMA/NWWDA 101/I.S.2-97 and AAMA 1701.2-85 for structural performance, air infiltration, water penetration and forced entry resistance.

They were tested under AAMA 1503-98 and NFRC 100-97 for thermal performance and ANSI Z97.1-1984 for impact resistance. If you need actual test data you can request it through the “ Contact Us ” page or just give us a call.
