Insulation questions, answered by experts

On average, attic insulation costs $1 to $3 per square foot, so for a 1,800-square-foot attic, you’d pay $1,800 to $5,400, including materials and labor. The cost can vary depending on what type of insulation you use, how many insulation layers you need, and whether you need to remove existing insulation first.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.
