Accredited Performance Testing

A full eight-test sequence.
Independently accredited.

The UCS curtain wall system was subjected to a complete accredited test sequence on a single full-scale specimen — air infiltration, static and dynamic water penetration, structural performance, repeat testing after structural loading, proof load and load to failure.
