HELP! New Anderson windows on older home
Hi, I am slowly replacing my old wooden windows with anderson 400 double hungs. I have a few questions that I am having a very hard time getting solid answers to. The house has vinyl siding over DOW styrofoam (with plywood corners). Here are my questions.
1) Do I/Should I put house wrap over the area where I am putting the next 2 windows.
2) Can I use asphalt and/or butyl flashing products over the foam board without problems. Can both types be used together?
3) Anderson suggests a dip cap. For single unit DH windows, is this needed?
Any help/suggestions would be great.
