Window and Door Testing

Today’s consumers demand more than ever from their windows and doors. To meet growing safety, quality, and energy efficiency standards, manufacturers rely on independent laboratories like Stork. Stork operates three unique windows and doors testing laboratories in Wausau (Wisconsin), Des Moines (Iowa), and Maplewood/St. Paul (Minnesota) to serve the fenestration industry.

Stork supports the fenestration industry with a broad range of testing and consultation capabilities and methods. Some of the services we offer include:

Air/water infiltration  Air and water infiltration testing is critical for judging the suitability of a window for an area or building. Techniques can be combined with variable wind velocities for a customized testing program.

Air/Water Structural Testing Structural tests are conducted to evaluate the integrity of a door, wall, or window by simulating high interior and exterior wind pressures.

Expert Witness Testing
Stork experts frequently consult on insurance, law enforcement, and litigation cases.

Miami-Dade County
Stork’s fenestration experts include engineers qualified to conduct testing to Miami-Dade County Building Code Compliance Office standards.

AAMA/WDMA Testing
Stork experts can test to AAMA 103.3 and AAMA 1402, as well as some WDMA standards.

ASTM Cycle/Impact
Simulated hurricane testing includes use of impact cannons to fire lumber missiles at a window or door sample, and subsequent simulated wind load cycling. These tests meet the protocol of the Southern Building Code Council (Miami-Dade County) and Texas Department of Insurance (TDI).

Acoustical Testing
Architects and engineers specify different Sound Transmission Class (STC) and Outdoor/Indoor Transmission Class (OITC) ratings for projects, depending on the building environment, i.e., along freeways, near airports or hospitals, etc. Stork operates 2 specially-designed in-house reverberation chambers to assign STC/OITC ratings. Field testing is also available.
