"Bottom line: I would hire this company again. Koala Insulation came and inspected my attic spaces with a infrared scanning tool. They looked at the level of insulation and found areas where the heat was penetrating more. They recommended specific actions and gave me a number of quoted options on the spot. I was then able to book the service within days of the initial visit. The technicians came and performed the service professionally and made sure to involve me where needed. I would hire them again."

"Build was exactly what I requested. Manuel was on the job site everyday and answered all my questions. He was available and responsive always. He wrote a contract out and was very professional about the entire process. He refused to accept any payment until the job was completed and I was satisfied. I would definitely hire him again and recommend him to anyone looking for an honest contractor."

Insulation questions, answered by experts

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.

Yes, guiding choices between open-cell and closed-cell foams based on needs.
