I see no negatives to using felt paper, we use #30 all the time. Many builders in coastal New Jersey have gone back to it. I have seen some problems with Tyvek deteriorating. Tar paper on my own house and almost every one I've built in the last 15 years.

Might be a regional thing. Nobody here uses felt for anything other than roofing and even that is getting rare. Most roofs we use a product called Titanium UDL. No more rips and we have yet to have a piece come off the roof under any weather. Tyvek needs to be installed correctly in order to work properly.

That would be one of the major causes for problems, noone takes the time to flash and counterflash properly, either Tyvek or felt paper. I have opened up walls with both products on them, I prefer what I saw with tar paper.

The nice thing about the felt is the variable perm that allows the moisture to escape if it does get trapped behind the wall.

Tyvek allows moisture out, but prevents it from coming in...felt is the old way.

That is exactly right. Tyvek will not allow moisture to pass through it unless it is in vapor form, essentially requiring it to evaporate before it can be transferred. felt paper will absorb moisture to some degree and wick it through.

Great point. I have seen literally hundreds of houses stripped of Asbestos siding that had 15# felt under it. They were built in the 1950s and 60s, the felt was in perfect condition. I've opened up houses built less than 5 years previous and the Tyvek was shreaded like old newspaper. I'll stick with tried and true felt paper.

In my experience, #30 lays flatter, but more importantly it contains more asphalt, which will resist moisture infiltration longer. It used to be that the number referred to the weight per square, but that no longer applies. Everything gets #30 felt paper.

I think the largest difference between Tyvek and felt paper is that Tyvek is much faster to wrap a house with.
I prefer felt paper. Just a tried and true material.

Much of what they say is true, exept for the surgical procedure that Gus Dering eluded too.  BTW, you my favorite pimp.
