Tyvek detail around windows
Help, the windows are here! so i'm all geeked out to check them out and install them. we wrapped the entire house, including the rough openings, in tyvek, BEFORE the windows arrived. our plan was to cut open the wrb, flash the sill with a piece of bevelled siding and flexwrap, then install the window. tyvek recommends making an i-cut in the wrb (one vertical cut in the middle from header to sill and two horizontal cuts from side to side along the header and sill) and wrapping the flaps of the tyvek around the sides of the window and fastening them. my thought is doesn't this invite water to migrate into the house? why not just cut the wrb to the actual rough opening dimensions? thanks again...
