    Hidden Seam Failures? We Put Flashing Tapes to the Test

    There are a lot of key differences, so no conclusions should be drawn from this testing. In any case, not all manufacturers report D3330, so we needed to pick one set of conditions and run as many tapes as we had through that one. We hope this testing provides some suggestive information.

    And here is a thought: maybe our “benchtop” testing will inspire (or anger?) some experts from PSA tape manufacturers or test programs to conduct some field or field-like service life performance testing. We’d love to see more manufacturers engage in testing along the lines of the Sustainable Building Solutions Test Facility Tremco has going, in partnership with the Department of Energy.

    A PassivHaus Renovation: Heritage Meets Energy Efficiency

    In the UK and North America, heritage buildings are under serious threat; our history is being bulldozed under the false mantra of energy efficiency when in fact, most buildings can be insulated, sealed and brought up to a much higher standard without throwing away the embodied energy stored in those bricks. That is why this Victorian terrace house in West London is so interesting; the builders are not just doing a renovation, but are going for the PassivHaus standard, tough to do in new construction and perhaps i…

    Proposed Changes to Standard 90.1 Address Metal Buildings

    Proposed changes regarding metal-building assemblies are being considered in the 2010 version of Standard 90.1 and are expected to be published in the fall. ANSI/ASHRAE/IESNA Standard 90.1-2007, “Energy Standard for Buildings Except Low-Rise Residential Buildings”, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.
