Infiltration that Attempts to Penetrate the Insulated Glass Air Space through the Glass Seal

Western Reflections door glass includes premium components that enable certification by the Insulating Glass Certification Council (IGCC) as meeting the requirements of ASTM E 2190. ASTM E 2190 is a harmonized standard test protocol adopted by the U.S. and Canada for evaluating insulating glass (IG) performance, durability, and longevity. There are three main parts to the standard:

The High Humidity Test subjects samples to high humidity and temperature with the objective of forcing moisture into the sealed air space in an IG unit. Specimens are tested for 42 days and subjected to 95% ±5% relative humidity.

Accelerated Weather Cycling simulates weather cycling from hot to cold extremes with moisture added during the hot cycle. Specimens are tested for 63 days and subjected to 252 cycles.

The Volatile Fog Test shows that components, or trapped impurities, will not out-gas a volatile fog, which could result in a deposit on the interior glass surface. No fog must be visible at arm's length.
