Types of Insulation

Insulation is designed to maintain a stable interior temperature regardless of the outdoor weather. There are four main categories for insulation. The type you choose depends on these factors:

  • The square footage of the area
  • The type of space
  • The effects of your local climate
  • Your budget
  • Your home's current R-value
    (R-value is the capacity of an insulating material to resist heat flow. The higher the R-value, the better it can keep heat in or out.)
Fiberglass Batts

Fiberglass batts are the most common and least expensive way to insulate your home. They are installed during construction and renovations before the walls or floors are closed in. Properly installed, it improves the energy efficiency of your home by 25 to 30 percent.

Blown-In Insulation

Blown-in insulation is made from white cellulose, a byproduct of recycled cardboard, newspapers and other paper materials. It provides excellent R-value which increases depending on the depth.

Spray Foam Insulation

Spray foam insulation is ideal for filling tight gaps and spaces that make a home drafty. It begins as liquid polyurethane that is sprayed into an opening or cavity. It expands to fills the space and then hardens into solid foam.

Reflective or Radiant Barrier

Reflective or radiant barriers work the opposite way as do other insulation materials but it has similar results. Most insulation slows down the flow of heat, but the thermodynamics of radiant barriers causes it to reflect the heat and cold. It is commonly used in attics to minimize the effects of scathing summers or frigid winters.

Cost of Insulation & Installation

The cost to purchase and install insulation varies regionally. The national average cost varies by material, with blown-in at around $880, fiberglass around $960 and spray foam around $1,100.


"They were to put in spray foam, but used foam sheets instead. They did a great job, and actually recommended a change that saved us considerable money from the initial estimate. They put clothes down every day and cleaned up carefully each evening. "

"Crew was totally professional. Kept us appraised of what they were doing and why. We asked the project manager, Mario Alvarez, at the last minute to add insulation to our ductwork and he immediately said no problem. And then his crew not only completed the extra work we asked for, but completed it on time and within the budget. Certainly would recommend this company for any type of mold remediation."

"They replaced my old attic insulation with new blown in and then put bats and a vinyl ground cover in my crawlspace. Extremely careful to keep dirt, etc., out of house, using plastic draped over furniture and taping plastic over work area . Very impressed."

"I was totally blown away (pun intended) with the service I got from USA. They were knowledgeable, professional, clean, and easy to work with. I had them do blow-in insulation in my attic and insulate my garage ceiling (which they upgraded to closed cell foam at no charge upon realizing the blown-in as quoted would not work in my situation). They may have been slightly higher in price then other offers, but they made up for it in professionalism and quality. I would/will hire them again and recommend them to my friends and neighbors."
