Hardie panel + moisture barrier?

Nov 10, 2004 1 Replies

I live in Cental Texas (30 mi E of Austin) and have a question about the appropriate installation of Hardie panel as exterior siding:



Doe this siding material require the installation of tar paper or Tyvek as a moisture barrier? I'm getting conflicting answers - some say no as long as the Hardie is painted and caulked.



Knowlegeable opinons greatly appreciated!



Thanks



Jon


Absolutely use the moisture barrier of your choice. I prefer tyvek. It is required for your warranty.
