"The crew at Bullseye did a great job adding additional insulation to my attic space. They got my home back up to the proper Rvalue, they also added some vents to help with air flow. Very professional and clean up was great. Can't wait to see the savings on my heating and cooling bills!"

Insulation FAQs, answered by experts

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.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.
