Defiantly on using closed cell, no moisture drip when using that. On a steel roof that develops condensation it will eliminate that. Do you have a banjo?I'm doing closed cell spray foam which has less off gassing then open cell. But like most things sprayed there will be voc's present for a few days which is also accelerated by humidity and high temps. By the time it's ready for insulation it should be late fall so the cure time should be perfect. Plus most times that the fumes linger one for to long is usually the error on the sprayer. He's either sprayed it to thick and/or has the wrong mixture settings. You know me I've researched this to death! ??
I've worn respirators my whole career. But with all the chemicals, lacquers and epoxy I've been exposed to I think my body is immune to fumes now. lol I've had employees spraying poly with no respirator while smoking a cigarette.![]()
