   after all the siding is on and the insulation from behind, pressing the tyvex agaist the sheeting does the tape do much good

   let me see 70000 6d nails through  siding, tyvex and sub sheeting, yeah taped seems help

   I admit, I live in a mild climate

   our inspectors no longer even look for taped joints

   but if I was someplace nasty I would pay more attention .........................and use felt

   by the way

   what kind of tape is used on felt?

   I don't know if Tyvek tape works well on Typar, but I do know why one would want to use tape. While a decent overlap may be sufficient where sheets of the material join, around window and door openings and other wall penetrations the tape produces a significant reduction in air leakage. This is especially true in retrofit cases, where the housewrap can't be wrapped through the rough window opening.

   When you've got a 15F northwest wind blowing at 20 MPH you really appreciate every little bit of additional infiltration resistance.

   Slightly different topic: My experience hasn't shown that Tyvek deteriorates that rapidly. Being exposed for the 2-3 weeks needed for even an amateur to complete a siding job doesn't result in any obvious deterioration.

   I had the same question today when I was at the lumber yard.  I didn't ask because around here, no one keeps up with info and adjustments as it becomes available.  Our lumber yards weren't even up on the problems with the new ACQ pt. 

   I have used the Tyvek tape with Typar and not noticed any problems.  I asked this somewhere and was told it didn't matter.  I use Typar over Tyvek because it seems to take the jobsite abuse better.  I need a good roller for the tape though.  Can you recommend one for me?

   We recently got to use the new Raindrop housewrap.  We were starting to use the Green-Guard board in place of OSB or Plywood where we could and the company that is selling that product came out to our jobsite because we are the only ones in this area.  We are saving about $10 a sheet by using it.  It is a hassle.  Anyway, they gave us a free roll of Raindrop.  I'm not doing the siding on the house that the Raindrop is being used, but so far everyone in our company who has seen it likes it.  The darker green (think healthy grass) looks good from the street and you can see through it so you don't have to mark lines to nail your siding to.

   Just thought I'd pass that along.  I do know that Typar makes some claims about their tape on their website, but I don't know if it really matters.

   Rollers for the tape - check out the 5" solid rubber rollers used to roll out laminate countertops after you place down on the MDF w/ contact cement.  They seem to have the right size and density to work well.

   Thanks for the tip.  I'm assuming I can get one at Home Depot or any hardeware store?

   Give it to habitat for humanity and ask for a receipt and write it of next years taxes.
