Question from AnneT
Debra,
Our next door neighbor is planning to have polyurethane foam blown on as a roofing material. As a person with MCS I am concerned about the toxicity of the material as it is being applied, and the issue of off-gassing after application. I am not comfortable being in the vicinity of the material as it is applied but I wonder if I’m over reacting. I have done some research on the internet and the articles I read state that polyurethane is safe after it is cured, or dry. Do I need to go elsewhere while the foam is being applied? I understand the whole process will take 2 or 3 days. I realize that the fresh air will alleviate some of the problems but I still have doubts. Please comment on polyurethane as a roofing material.Readers experiences are welcome too.
Just FYI, the neighbor is being very cooperative and that is helpful. But he may decide on the foam roof anyway.
Thank you,
Debra’s Answer
I would leave the area while it is being applied for sure, and stay away at least a few days while it is curing.
