If so should I allow vent space with a furring strip between the exterior wall covering and the insulation? Or what other precaution?Mel
know a man who had to put new plywood on his entire roof up in SE Alaska because condensation could not evaporate. He had not provided a vent space between plywood and insulation,
A/C or no A/C?If A/C then no vapor barrier on interior walls. If no A/C, not 100% sure but I think still no vapor barrier, in your climate.
In a Hot-humid or mixed-humid climate my understanding is no vapor barrier on the interior anywhere; walls, ceiling/roof and floor when there is interior cooling. When the interior is cooled if there is a vapor barrier or even vinyl wallpaper, the moisture will come from the outside humid air through the wall and condense on the vapor barrier in the wall.That's all gleaned from buildingscience.com
