Pressure sensitive tapes (PSAa) can make or break the continuity of your air and weather barrier—ensuring a durable, high performing enclosure, or putting it at risk. Yet we have little way of knowing whether tapes will stand the test of time. We can’t visually inspect them once the cladding goes up. Nor can we rely on existing testing standards, which aren't suitable for the products used in construction and the cold, windy, wet, dirty conditions in which they are installed. Three years ago Peter and Dave took matters in to their own hands, setting up a testing facility to measure the performance of routinely installed products under field conditions. They will share the results of their testing and what it means for field practitioners.
