Window installation — sealant offgas issues
About a month ago, i had some windows installed in my basement. They were installed on a cold day, about -5 degrees Ceclcius (20-25 Fahrenheit). The weather here has gotten unseasonably colder. The sealant used to put the windows in place was Mulco's supra expert, and seems to be dry on outside, but some areas are still soft.
Ever since the windows were i basement, the back of my throat is slightly sore, but only when i enter the basement. At the first week, there was a definite solvent smell, but the smell went away, after i attempted extreme air sealing and removed the clear sealant from one of the 5 windows (where i think it was coming in from. The smell has not come back. The sore in my throat only occurs on some days, not all. My theory, is that this is only occuring on cold days where the furnace is blasting. It is an old house that uses concrete block, the hollow cores are where the leakage is coming from, the mortar joints aren't the best either. (the basement is in the process of renovating).
All other materials have been ruled out.
THe flashing for the windows have not been installed yet (windows are covered with board temperorarly) thinking it needed to air out. I havnt aired out the space that much becuase of the temperatures.
I am not sure at this point, if the cold weather has not given a chance for the sealant to cure, or if i have a sensitivity to something in the sealant. Either way i don't really know what to do.
I need to know two things.
1. Are there more environmentally friendly alternatives to thermoplastic sealant for this application, or one that has low voc's
2. What should I do? Is there something simple i am missing. I want to be able to work and live in my house.
