What is the proper method of installing new vinyl windows over sheathing
which has been strapped due to the requirement of the siding manufacturer?
The sheathing is already housewrapped and the strapping is outside the
housewrap. Each window opening has strapping all around it. Where should the
caulking be and should more strips of housewrap be cut and taped over the
windows nailing flange and strapping? Thanks for any help.

I don't know if it code or not, but any waterproof fabric over the
strapping can only add to prevent water from entering the windows's
When my house was built back in 1984, the builder used roofing felt as
the house wrap. The felt was wrapped into door and window rough
openings. After the vinyl windows were installed, strips of felt were
stapled over the strapping. Starting at the bottom, a piece across the
bottom strapping, then pieces down the side overlapping the strapping
and bottom piece of felt, and finally, a strip across the top
overlapping the strapping and top ends of the side felt pieces.
I don't know what strapping is or how it was done.
As for sealing your windows check out a product called protectowrap. Use it
instead of house wrap caulk or tin. Almost all the better builders are using
it in new construction around here.
You can buy it at most Home Depots or read about it here;
I find a j-roller aids in installation but isn't really necessary.
