Possible allergic reaction after fiberglass replacement?
I just wanted to ask a quick question to see if anyone thinks or has had experience with a client getting respiratory problems after fiberglass batt removal and replacement? We had a rodent infestation in our crawlspace and had the old infested fiberglass removed (after trapping and killing all rodents) and new fiberglass batts installed. The new batts are the formaldehyde free Eco Batts by Knauf. They were installed on the ceiling of the crawlspace, under the floor of our living space. The installers were never in the living space of the home. The crawl space access is outside, however we do have lots of air leakage through the floorboards as identified on an energy audit. The occupants were not home during the removal/install process.
Since the fiberglass was replaced, 2 of the occupants have had respiratory symptoms (runny nose, cough, throat irritation and soreness with the main symptoms being a 'tickle" in the back of the throat which causes a cough reaction), the other occupant just reports the "throat tickle". It's been over a week since the work was done. I am concerned this is a reaction to either chemicals in the fiberglass that I was unaware of beforehand when researching the product (I thought the Eco Batt was a good "green" option), or fiberglass fibers that made their way into the home. However I am aware it could be just coincidence and could be caused by other issues such as perhaps a virus or allergy to an unrelated substance.
The main reason I am asking this is (see my other thread) we need to address the air leakage from the crawlspace through the floor anyway, and are deciding what to do about that. (Replace current insulation with spray foam or caulk gaps and re-hang the fiberglass or possibly replace it with cotton batts) Having information linking either the new insulation to the symptoms we are having or not will help us ultimately figure out how to proceed.
