Insulated Glass Testing

Certification of your Insulated Glass ensures their performance and therefore their widespread use in the building industry.

We subject Insulated Glass units to environmental exposure to measure their performance for seal durability, weathering, and fogging. Insulating glass units endure a combined total of 16 weeks of exposure to extreme temperature variations, ultraviolet exposure, and humidity. The time frame consists of the following:

The I.G. units arrive at the facility and they are immediately placed in our climate controlled Insulated Glass Test Facility to stabilize temperatures of the glass and sealants. 10 units are typically chosen for the testing, 6 of the 10 actually go through the complete test cycle, 2 of the 10 units go through the fogging test only and the remaining two are stored as extras in case of accidental breakage of one of the test samples. All ten samples are initially subjected to a Frost Point test to ensure the durability of the sealants prior to commencing the test procedures.

Two samples are subjected to the fogging test for a total of 7 days.

The six test samples are placed in the High Humidity Tank for 14 days, then removed and stabilized to ambient temperature for 24 hours. The samples are then Frost Point tested and placed in one of our three Accelerated Weatherometers for a period of 63 days. The samples are removed and again stabilized to ambient temperature for 24 hours, frost pointed and placed back in the High Humidity Tank for 28 days and once again removed, stabilized to ambient temperature and frost pointed again.
