Can I use Tyvack under the Styrofoam or leave the selvage?

Jake-

I am preparing to reside in an older house. Built around the mid 20's it has oak planking as original sheathing. Then 15lb felt and something similar to selvage in a pattern to look like brick siding. Can I leave the selvage and go with either fan Styrofoam type 3/16 insulation before the vinyl or can I use Tyvack under the Styrofoam?

Thank you, William

William,

I don’t know why you couldn’t use a insulation board then cover it with Tyvek.

Q. I’d like to know what kind of long-life bulbs to use in a ceiling fan. We bought dim-able compact fluorescent light (CFL) bulbs and they did not last long.
