I would concur; I belongs on the outside of the sheathing. Placed
behind, it would stop or restrict vapor at that point where it would
condense and rot the sheathing

Subject: [Florida Code Talk] House Wrap

 

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.  

 

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?

 

Thanks,

 

Ken
