Hi, I built and sold my first spec, I was the gc. I hired a guy to build the home, under a builder's contract. Sold the house, now 4 months later I have frost coming in the bottom right and left corner of each window. I found out he used tyveck tape to flash windows instead of flashing tape...
as for tyvek tape ,i would prefer at least 4" around window due to leaks i have seen in the lower corners of windows when doing repairs . problem with what i would like is that in remodels or window replacement i just do not get that much space to work with . the tyvek tape doesn't seem to be sticking well ,doesn't seal around additional fastners going through it .it will not seal well over fastners heads on the flange due to it's stiff nature .
not so much concerned about the head flashing being on top of building paper due to the eves -though seriously it is not doing much .
am i missing anything else .
this is real world situation , worth asking for more insight .
