Glass Seal

ODL Doorglass uses premium components to become certified by the IGCC as meeting the requirements of ASTM E 2190 is a standard test protocol for evaluating insulating glass (IG) performance, durability, and longevity. There are three main parts to the standard.

High Humidity Test
Samples are subjected 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.

Volatile Fog Test
Tests to show 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.


ASTM E 2190 is a harmonized standard adopted by the U.S. and Canada.
