Window Water intrusion Testing
Mazza Testing was contact to investigate waster entering into this structure (which was vacant for a very long time). Water intrusion was described as entering into multiple different locations throughout, according to the management company. Our initial infrared scan of the facility showed that water was in fact getting into the building from the turret, storefront glazing and roof.
No formal standardized test such as the AAMA 511-08 or ASTM E1105 was chosen to replicate any leaks here. However, we did use our calibrated spray rack system to test the components. We chose to test the glazing systems by way of a calibrated spray rack, and the static 15 minute test for each 8′ x 8′ section of glass. For the roof, we ended up just using the spray wand with the calibrated spray nozzle. This, as opposed to using a water hose at full blast.
The roof was a ballast or rock covered hot roof. The flashings by all accounts, were old but did appear to have been maintained. On the other hand, when viewed from the bottom side of the roof, water appeared to leak from the flashings.
Although we didn’t perform any destructive testing here, we felt with the use of the infrared camera and our technique, we’d be successful at sourcing the leak. Indeed once tested, the roof-to-wall flashing did end up leaking.
Our client was concerned that during the previous rain, there were puddles on the floor in the vicinity of the storefront glazing. For this, the calibrated spray rack would have to be employed. Despite not using an interior differential pressure chamber, there was no reason why the glazing system wouldn’t leak under normal testing water pressure. In fact, the management company even stated that the leaks were from light rains. They really just wanted a “quick n dirty” test.
No matter where on the storefront glazing system we tested, it leaked. Curtain wall, doors, fixed windows… you name it. So after a few minutes of testing different components, we were pretty much done. Suffice it to say, the glazing throughout needed some serious service.
