Wait a minute! You took all the siding off, installed Tyvek, and then reinstalled the same siding? Wow. I'd love to do that too. Or was it new siding? Did your house already have wooden sheathing?
Our house has 2x4 walls, then 1/2" thick tinfoiled-styrofoam, then aluminum siding. No Tyvek, and no wooden (OSB/plywood) sheathing. Ants, flies, ladybugs, etc. get in through the @#$! big holes in our styrofoam made by poorly aimed hammers of lazy siding installers. Must have had strong winds that day. ;-/ We found SO MANY holes when replacing drywall. Grrrr.
Would you recommend Tyvek for preventing those bugs? Does it make your home any quieter?
