Types of Insulation

At CFI Insulation, we install a variety of materials for residential re-insulation projects throughout Knoxville, TN:

  • Fiberglass insulation: Fiberglass insulation, which has been used in homes for decades, is available as loose-fill or batts. Fiberglass is made of tiny glass fibers and is often installed in attics but can be used to insulate walls and crawl spaces as well.
  • Spray foam insulation: Typically made of polyurethane, spray foam insulation is applied wet and expands into thick foam. Spray foam can be installed in crevices and hard-to-reach areas and can help reduce air infiltration.
  • Cellulose insulation: One of the most environmentally friendly materials, cellulose insulation, consists of up to 85% recycled material. It can be installed in any area of a home.

Residential retrofit insulation, or re-insulation, projects entail adding more insulation to existing homes. Insulation doesn’t perform flawlessly forever, and there becomes a point when old insulation needs to be removed, and new insulation needs to be installed.

Re-insulating your home can help you reduce your energy bills and live more comfortably no matter the season.

Improve the Insulation of Your Home in Knoxville, TN

At CFI Insulation, we can provide the insulation services you need to keep your home comfortable without spending a fortune on heating and cooling bills. Our insulation services in the Knoxville, TN area include:

Attic Insulation

By far, the most important place to insulate in any home is the attic. By ensuring you have at least an R-49 to R-60 insulation rating in the attic, you can prevent heated air from escaping the living area during the winter. Likewise, in the summer, attic insulation can prevent the living area from absorbing the heat from the hot attic and the underside of the roof. Fiberglass batts, blown-in fiberglass, cellulose and spray foam insulation all offer great insulating performance in the attic.

Basement Insulation

Insulating your basement can significantly cut down on energy costs while preventing moisture and mold damage. Basement insulation can also be a great first step towards creating a finished basement, complete with extra living space, storage areas and more. Rigid foam or spray foam are excellent moisture-resistant choices for the basement walls, while fiberglass or mineral wool batts can be used between the floor joists.

Crawl Space Insulation

Whether your home has a vented or unvented crawl space, insulating the area can help to lower your heating costs and prevent moisture damage. Typically, the best crawl space insulation is moisture-resistant products like rigid foam board, spray foam insulation or mineral wool insulation.

Wall Insulation

Adding as much insulation to the exterior walls as possible can greatly improve your comfort and reduce energy costs. In new homes, fiberglass batts, mineral wool or spray foam are excellent choices for walls, while blown-in fiberglass or cellulose is the best choice for finished walls in existing homes. Extra wall insulation can be added with rigid foam beneath the siding.

Floor Insulation

Keep your feet warm and reduce your energy costs with quality floor insulation. Fiberglass batts or mineral wool can be added to floors in new homes, while finished floors can be insulated with spray foam, cellulose or blown-in fiberglass.
