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></font></p>

<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>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></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>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></span></font></p>
