First time builder here building a 13’x23′ shed roof cabin with my dad in central West Virginia. Three weeks ago I had 2″ of closed cell spray foam installed in the walls/floor and 3″ in the ceiling. Walls are 2×6 and floor joists 2×10.
I recently started spending more time inside with a heater running and notice a slight paint/chemical smell. If inside for 30-60 minutes I can feel it in my throat/lungs, like when you use a strong cleaner without good ventilation.
The installer came out and cannot detect any odor but wants to put 6 mil poly on the walls and ceiling.
A couple questions:
– Will the odor go away with time?
– Will plastic sheating block the odor?
– Will adding this plastic cause any problems with moisture getting trapped in the walls? I plan on adding a mini split but will not continually condition the space.
Thanks for any help!
