The Fenestration and Glazing Industry Alliance (FGIA) Hybrid Fall Conference in Chicago hosted a variety of discussions and events, including air infiltration and water penetration tests that are of “great importance to the industry,” says Bill Bahn, president of Hightower Labs.

The tests, ASTM E783 and ASTM E1105, were performed by Bahn on a window unit on the ground level floor of the Fairmont Chicago Millennium Park.

The tests, ASTM E783 and ASTM E1105, were performed by Bahn on a window unit on the ground level floor of the Fairmont Chicago Millennium Park. Participants were able to witness the laboratory equipment used for the evaluation of fenestration products in the field, the construction of an interior test chamber and the placement of the water spray rack on the exterior of the building.

The first test, ASTM E783, is a measurement of the volume of air that flows through a test specimen while under a pressure differential between the interior and exterior, says Bahn. The air flows from the high-pressure side to the low-pressure side, and airflow can be measured in the chamber.

The second test, ASTM 1105, is known as the water test.

“It’s a qualitative test where we impose a stringent environment on the test specimen and then observe the behavior of the test specimen in that environment,” Bahn says. “It’s pass or fail. There’s either water penetration or there’s not.”

Despite the importance of the two tests, they are underutilized in the market, which has created an unequal playing field, Bahn says.

“When performed properly and in a volume that’s appropriate, that playing field can be evened,” adds Bahn.
