Dow Expanding foam
I have read several posts regarding off gassing off 2 part foams both closed and open cell….However my question specifically relates to using the Great Stuff Dow Expanding foam around HVAC supply vents. My concern is any off gassing that may occur around these supply vents if I use this foam. I have some minor gaps that I was going to seal to enhance the air barrier. But have concerns regarding any off gassing AFTER the foam has completely cured.
Anyone have any insights into this.
