Hello, after doing a lot of 'research' and considering options, I chose to go with a closed cell spray foam in my garage/studio conversion. My goal was to keep as much height in ceiling and highlight the rafters, while minimizing wasted energy cooling it. The company I chose had high ratings. The whole job started off wrong (like showing with black spray foam when I requested white) and on and on, I could write a chapter, including that they covered the rafters I said I wanted to see, the whole reason I chose closed cell. The had to scrape it off. They also showed up with black fire retardant paint, duh. They've responded and tried to correct stuff, however, now we are at an impasse and I would appreciate any insight as to if I should just move on or insist on some change. A) After a lot of rain (several days worth) the room was fuming with smell of ammonia, so much so that it burned my eyes, lungs, and was absolutely inhabitable, this stench lingered for several days. the sales rep came out and smelled it, he agreed it was bad. His boss came a few days later, smell had dissipated. Says he can't do anything unless he smells it too, and that they 'never heard of such a thing'. and B, the shrinking and warping of the product, as insulation its not really covering like I expected it would. They say this is 'normal' My plans include adding some kind of finished ceiling such as wood planks, but terrified to move forward until I know if this is normal, dangerous, wrong, or just ok? any ideas, experience, help? Im in Florida, work was done in April this year.
