<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
color:navy'>I have seen this practice as a NOT to be performed. It likely
ties back to northern construction details where the moisture vapor moves from
the inside of the building towards the outside in the winter time. The
observations you described are not suitable for hot humid climates. I
would recommend the vapor barrier / drain plane on the outside of the sheathing
with an air space capillary break between the sheathing and the drain
plane. <o:p></o:p></span></p>

<p class=MsoNormal>Has anyone ever heard of putting the house wrap on under the
sheathing (OSB)? I’m doing a siding replacement job where the lap siding
had failed (can’t remember the name of it but it had a class action law suit
against it several years ago). There are some spots where the siding
allowed the OSB sheathing underneath to become saturated and thus rotten.
As we were removing some of the bad spots of sheathing to be replaced we found
that the framing had been covered with TYPAR. It’s unfortunate that
it wasn’t on the outside of the sheathing as it would have made our siding
replacement job MUCH simpler. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I was just wondering if anyone had ever seen this done and
if it was ever an accepted practice to do this or is this just another example
of how NOT to build a house. I know the code (703.2) states that the
weather-resistant material will be applied over studs or sheathing but I’m
pretty sure this is not intended to mean you can/should put it under the
structural sheathing, right?<o:p></o:p></p>
