I have a 3100 sq ft house and received a quote of around $6,000 for spray foam insulation. The contractor claims it will lower my energy bills significantly—around $350 per month in spring and $800 in winter—and help maintain a consistent temperature across all rooms. However, I have some concerns: I believe spray foam can be toxic and might release harmful gases. Additionally, I've read that it can trap moisture between the roof shingles and the wood, which worries me since we just spent $25,000 on a new roof. I'm looking for safer alternatives for insulation that I can explore and get quotes for instead.

If you're looking for something more eco-friendly, you might want to look into cellulose insulation. It's made from recycled paper and is treated for pest resistance. It doesn't have the same off-gassing concerns as spray foam, and it could provide good thermal performance too! Just make sure whatever option you choose addresses your insulation needs and moisture concerns!
Spray foam is commonly recommended for sealing big gaps in houses, but if you're concerned about toxicity, there are other options. Caulk works well for smaller gaps, and if you're looking for full insulation, consider fiberglass batts or rigid foam boards. They won’t off-gas like spray foam, and you could still achieve good insulation if done right. Just make sure to check for proper ventilation in your attic if you go this route. It might help to get a professional opinion for your specific situation, though!
Definitely agree about considering fiberglass or rigid foam! Just make sure you have good ventilation to avoid moisture build-up.
Cellulose sounds like a great option! Good to know it’s eco-friendly, too. I'll look into that!
