   If you check the manafacturer's literature, I think you will find that they recommend that it not be exposed for more than 3 months.  UV rays, etc, cause it to degrade.  Other house-wraps may be different.

   Hi Mike:

   I'm not a builder...an astronomer building his own house...

   With that in mind, I've had tyvek siding for two years now!  The log siding hopefully will go up this fall, but that starts in 3 weeks, and ends in 3 months!  LOL

   I'm in the fingerlakes of NY...similar weather...

   My Tyvek has held up extremely well.  I have lathe strips holding it down tight...it is all properly taped and whatnot.  My sheating underneath looks wonderful.  I have checked this a few times.  I am nestled in the woods...so I am shield from massive direct wind.  I have 2' overhangs so in all but the most driving of storms I do pretty good about staying dry.

   I think what DuPont talks about is degragation in the Tyvek material in UV exposure.  In this area, it's cloudy 95% of time time...LOL  As far as protecting your house, I think it will be fine...my experience.  Tape, lathe, don't leave any corners free flapping in the wind...it will drive you bonkers AND could give it a place to start tearing/pulling free.

   I actually wrapped the lower section of the house with a second layer before last winter...as the siding never got on then either. 

   If you want the Tyvek as a true Tyvek layer, in the summer next year, before you hang the siding, you might want to rip down the old and hang new.  10' rolls go on quickly...with help.  Don't stalpe...use lathe pieces instead. 

   That's my experience. 

   Sounds like you are having a fun project!  Hope you enjoy yours as much as I do!

   Of the wraps, I prefer TYPAR, for a number of reasons, one of them being it's longevity when exposed to UV over that of TYVEK.

   Besides, it's a little easier on the eyes!

   I usually put it up with plasti-cap nails,  but I suppose for a winter's exposure, the lath would be a good idea.

   Sounds like a fun project.

   We've been building our house (my hubby is doing the building, I'm the helper) for the last couple of years.  We've got the tyvek siding too.  We called DuPont and  they said this is a rather common situation.  Their advise is to cover over with a new layer of tyvek, just before the real siding is installed.  They did say that any tears in the old layer should be taped first.  You don't need to take the old tyvek off unless it's in very bad condition.  We are now doing our house one side at a time.  As we progress around the house, we will add the new tyvek.

   We've had a chance to observe tyvek for - hmmmm (something over a year) and UV does cause deterioration.  We installed ours with the plastic cap nails and it has held very well.  We're in Oklahoma and the wind does blow.

   We're also using the tyvek window treatment, and it seems to be great stuff.  Easy to install, but very expensive.

   This is my first post, but have been lurking for awhile.  We really appreciate all the good information and humor.

   It shouldn't be a problem; lots of houses here are left in Tyvek/Typar overwinter, and I think our climate is perhaps even a bit more wintery than yours (100 mi N of Montréal).
