(For background on WTF and its prior tape tests, see “ Shocking Truth About Tapes Emerges from Wingnut Test Facility! ”, and to find GreenSpec listed tapes, see Flexible Flashing .) Dave Gauthier and I decided two things at the end of our last round of testing: We needed a more-realistic, longer-term, “straight-pull” tension test. We needed a test that reflected the “bellowing” pressures that tapes see in real installations, driven by wind events. read more
