Do I need house wrap behind vinyl siding?

There is no logical reason not to have house wrap under vinyl siding, and many authorities strongly agree that it should be viewed as mandatory, even if your local building codes don't necessarily require it. Another benefit of quality vinyl siding is that it is highly water-resistant when correctly installed.

Do you have to replace house wrap when replacing siding?

There is no problem with applying a new layer of housewrap over the old. In fact, it's recommended. Aside from the likelihood that there have been advances in the housewrap membrane itself over the last 23 years, you can't be sure how long the existing housewrap was left exposed to the sun before siding was installed.

Can house wrap be used inside walls?

The house wraps are designed to allow water vapor to pass through them, but stop liquid water. Vapor barriers are put on the inside face of wall studs in cold climates and they're put on the exterior of homes in hot and humid climates. You want the vapor barrier as far away from the cooler wall surface as possible.

Does it matter which side of Tyvek faces out?

If you install it on the inside BACKWARDS (the Tyvek name facing the wall) moisture will still be able to penetrate the outside wall but will not go thru the Tyvekin that case it would act like traditional plastic sheeting.

What goes on first insulation board or house wrap?

You plan to install 2 or 4 inches of rigid foam on the exterior of the wall sheathing, followed by vertical rainscreen strapping and siding. For example, I've heard that the housewrap belongs between the foam and the strapping, “because that way it's easier to integrate with the flashing at the logical drainage plane.”

Can you paint Tyvek house wrap?

Tyvek is made of a polyethylene plastic that is designed to be resistant to moisture and chemicals. Any type of paint is just going to coat the surface and really won't penetrate and die the fibers. You can paint it, it just won't last forever. These fibers are woven together to create the tarp-like material.

  3. Paint thinner (Note: depending on finish, 2 and 3 may be reversed).
  4. Acetone. (Will melt/dissolve many furniture finishes, Also ruins most stone sealers.)
  5. Denatured alchohol. (See #6.)
  6. Lacquer Thinner. (Will melt latex paint.
  7. MEK. Methyl-ethyl ketone.
