I'm putting in flanged windows in a wall sheathed with Huber's Zip System (OSB with integrated WRB). Should I use just butyl tape over the top flange, or should I sandwich a drip cap between two pieces of butyl tape?
On a different note, I think I'm going to tear out the bottom sill. Should I replace it with a ripped down 2x4 ripped at a -10° bevel? I'm using FlexWrap as a sill pan.
Thanks, Tom. I ended up ripping a 1x4 I had lying around. I'll go with a metal drip cap. Should I go over the trim with the cap? I didn't have them on any of the windows already installed in the house, so I can't use them as a reference. Do you typically paint them to match casing or the jamb?
