What is the proper thickness of spray foam insulation?

Many factors determine how thick spray foam insulation needs to be. All insulation is rated by R-value which is a rating of thermal resistance. The higher the R-value, the higher the thermal resistance. When installing fiberglass insulation, cellulose insulation or mineral wool insulation R-value is clear. Understanding the R-value of spray foam insulation is a bit different. Spray foam insulation R-value depends on the type of spray foam insulation being applied.

There are two types of spray foam insulation: open cell and closed cell. Depending on the manufacturer, open cell spray foam insulation has an R-value of approximately 3.5 per inch. It is a low-density product that is often used in interior walls and other areas that require some moisture permeability. The R-value of closed cell spray foam insulation is different. Depending on the manufacturer, closed cell spray foam has an R-value ranging from 5.0 to 7.0 per inch. Closed cell spray foam is more rigid than open cell spray foam and is used in areas where moisture permeability and a higher R-value are necessary.

To be sure your home has the right amount and type of insulation, consult a qualified insulation contractor. Whitson Insulation of Grand Rapids has the training and expertise to properly advise you on the amount of insulation your home needs. Contact us to discuss your next project.

What is spray foam insulation?

Spray foam insulation insulates and seals air leaks in one application. Spray foam insulation is comprised of two products that react when combined. This reaction causes the foam to expand and, when installed, fill cracks and crevices. Spray foam insulation also dampens sound transfer and deters mold growth.

There are two types of spray foam insulation – open cell spray foam insulation and closed cell spray foam insulation. Open cell spray foam is lighter in weight than closed cell spray foam and is flexible. Closed cell spray foam insulation is heavier and more dense than open cell spray foam. Closed cell spray foam has a higher R-value than open cell spray foam and is more resistant to moisture. It is frequently installed in areas such as crawl spaces where there is higher moisture composition.

What is Fiberglass Insulation and How Does it Work?

Fiberglass insulation is a traditional insulating material and the type most people think of first. It is comprised of thin glass filaments that are woven together to create fiberglass batt insulation. Fiberglass insulation is also manufactured as loose product.

Fiberglass insulation acts as a thermal barrier to prevent heat from moving to a colder area – from outside to inside your home in warm months and from inside to outside your home in cold winter months. Fiberglass insulation is available in two forms: blown-in (loose-fill) and batt (blanket) and can be installed in almost any area of your home including walls, attics and crawl spaces.

Adding fiberglass insulation can help reduce your energy bills and make your home more comfortable all year long. Call us at Whitson Insulation and we can answer questions about your next insulation project.

Is Spray Foam Insulation a Good Solution?

Spray foam adds thermal protection and seals air leaks in one application. Spray foam insulation is made up of two materials. When combined, the reaction causes them to expand and harden. There are two types of spray foam insulation: open cell and closed cell. Closed cell spray foam is more dense than open cell spray foam and has a higher R-value. Open cell spray foam also adds R-value and seals air leaks but is less dense than closed cell spray foam.

Some advantages of spray foam insulation:

  1. Because it fills even the smallest penetration points, spray foam insulation is an effective moisture and air barrier.
  2. Spray foam insulation can provide structural stability by expanding into cracks and crevices in your floors, ceilings and walls.
  3. Helps keep out pollutants that may enter the interior of your home.
  4. Because it is impermeable to water, its insulating properties are not compromised by moisture.
  5. The combination of R-value and air sealing makes it an ideal product to manage your home’s temperature.
  6. Can help reduce noise transfer.
