I'm thrifty and hate to pay for name brand if an alternative is
available.

Why yes. If you are not doing stucco or vinyl siding you could use 15 pound
saturated felt (University of Mass tested superior performance to Tyvek) or
good old red rosin paper. Both will give you equal proformance BUT unlike
Tyvek they cannot be exposed to the elements for long. You must side over
them as you go. If rosin paper gets wet it must be torn off and replaced.

I certainly agree with your comments - except the rosin paper seems
not tough enough.

Yes, rosin paper. We used it for many years here in New England before the
marketing onslaught of Dupont corporation, convincing people like you that
an air barrier that is not plastic and actually absorbent is somehow a bad
thing. I have rosin paper on my own house (approx. 20 years old) and have
done a couple of additions and have found the plywood to be in pristine
condition. I only use Tyvek on my new constructions now, not because it is
better, but because it basically weather-tights the house while I wait for
my siders to not show up on time! It allows me to accelerate the schedule
(or at least not delay it) and therefore make more $$. Well worth the extra
cost.

Tough enough against what? Once it is covered with siding what does it need
to be tough for?
See above response for more. I already said that it has to be installed as
you side the house. You can't leave it up overnight. Not tough enough for
that.
Keep in mind that this is a very old (1981) argument. A windbreaker made of
cotton is better or worse that a windbreaker made of plastic? Depends on the
wearer.

People like me? The DuPont corporation hasn't convinced me of
anything. I'm siding my own house right now with cedar shingles and
they're going over 30# felt. Rosin paper does not seem like it would
keep water off of anything for very long, but hey, maybe I'm wrong.
I'm going to post on the FHB forum and see if they think it's OK.

Felt (saturated) is better than rosin. No question. But keep in mind that
this material is acting as an air barrier, not a moisture barrier or a rain
screen. Any moisture that gets into the wall from the inside you want to
penetrate the material to get it out of the walls (unless you are in a humid
southern climate, now you want a vapor barrier on the outside and that's a
whole new ballgame). If you are using vinyl siding or a one coat stucco
system it is also a new ballgame. Now you need a rain screen. One product
does not fit every circumstance, you need to use the best material for your
application.

I have a small 2' by 3' area that I now have exposed as I replaced a big window in a bathroom with a much smaller one. So what can I get away with for a vapor barrier on that small space in=stead of buying a whole roll of Tyvek?
