I was contacted by Gabe Linehan this morning regarding your request for clarification of the
building wrap issue at the window openings. In the past, I too have seen the building
wrap/water-resistive barrier (WRB) applied prior to the adhesive flashing at door and window
openings.
I spoke with the local sales representative of Sierra Pacific Windows to review their
recommended installation practice that Gabe followed while installing the windows. As shown
in the attached PDF, they recommend that the adhesive flashing (in this case Vycor, see
attached PDF -Method A) is applied directly to the exterior sheathing. They are following
the ~ (American Architectural Manufacturers Association) recommendations of sealing the
window flange to the sheathing in case water gets behind the WRB.
Finally, the Tyvek WRB is applied and taped or caulked at the window/door opening per their
recommendations. See attached PDF, specifically pages 8 & 9.
As long as Gabe follows these guidelines, I feel he would be in compliance with the
recommendations of the various product manufacturers . Please let me know if you have any
other questions or comments .
Thank you for your time in this matter .
