Dan Phillips replied to Martin Newmark's discussion Best Practice for Retrofit Insulation on Modern Knee Walls in Attics
"It is important to also remember the key junctures where the top of the kneewall meets the roof, and where the bottom of the kneewall meets the floor/ceiling.  Getting an air barrier installed at those two details isn't always done well.…"

Dan Phillips replied to Jonathan Ballew's discussion lifespan of air sealing materials
"I don't think I'd go any further out than 10 years for major air sealing (done at the high pressure boundary).  That's assuming the foam is getting pretty good contact with the surrounding wood or other mechanically fastened A/S…"

Dan Phillips replied to Griffin Hagle's discussion Which is the valid draft test?
"I'm guessing that is the short metal tube that comes with the DG.  If that is the case, go with perpendicular to the pipe.  Might want to trim some of the pipe insulation off as well before the job is completed.  The insulation…"
