How much insulation do I need?

There is no “one” answer to the question of how much insulation your home needs. The short answer is that your home needs enough insulation to properly protect it. There is a lot more involved in determining how much insulation your home needs. Your climate is the biggest factor that determines how much insulation your home needs, followed by local building codes, air leakage, your home’s construction and so on.

In a cold climate like Michigan, a higher R-value is required than would be necessary in warmer climates. Attic insulation in Grand Rapids, Michigan should be an R-value of R-48 to R-60. How thick this should be depends upon the type of insulation that is installed (e.g., fiberglass versus spray foam).

When adding insulation consider sealing air leaks in addition to insulating. Insulation creates a thermal blanket that helps reduce heat transfer. This thermal blanket helps keep conditioned inside air from escaping the home. This thermal blanket may not prevent all conditioned air from escaping. Traditional insulation materials such as fiberglass insulation and cellulose insulation are porous materials that allow some air flow, not to mention the air gaps around the insulating material. Sealing air leaks around wiring, duct work, etc. is an important step to help keep even more conditioned air in your home. Spray foam insulation is a unique product that insulates and seals air leaks in one step.

Cellulose insulation dense packed in wall cavity

What is cellulose insulation?

Cellulose insulation one of the oldest types of home insulation. Cellulose insulation is plant fiber that is manufactured mostly from recycled newsprint.

Cellulose insulation is manufactured as a loose-fill product and is installed with a machine to either blow in or dense pack. Cellulose insulation can be blown into attics to add R-value to this open space. Densely packed cellulose is typically used for retrofitting a home or office. By dense packing the cellulose into wall cavities it provides thermal resistance and reduces sound transfer.

Stabilized cellulose has water added to it and is typically installed in new construction before drywall is added. It provides the same thermal insulation and soundproofing as dense packed cellulose insulation but is used in open walls before the cavity is closed.

If you have questions about cellulose insulation for your home or office, call Whitson Insulation and our experienced professionals can help you.

What is Insulation?

Insulation is any material that is used to fill spaces in your home including gaps and crevices. The purpose of insulation is to reduce heat flow by stopping heat transfer or reflecting heat. Insulation is also used as a sound barrier. Different types of insulation are best used for different purposes for electrical, thermal and soundproofing.

Insulation comes in many different types:

  • Fiberglass insulation is manufactured from recycled glass and is widely used. It is installed as a batt (also known as a blanket) or as loose fill (also known as blown-in).
  • Cellulose insulation is made primarily of recycled paper. It is often used to dense pack into closed spaces and is commonly used for soundproofing.
  • Spray foam insulation is applied as a liquid and expands to fill a space. As spray foam insulation expands it fills leaks. Spray foam insulation insulates and seals air leaks in one step.
  • Radiant barrier insulation is often used in warm climates and helps reflect heat away from a building.
  • Rigid foam insulation is manufactured in sheets. It can be cut to fit any space and is often used in new construction.
  • Mineral wool insulation is also called rock wool insulation. It is manufactured from rock that has been spun into fibers.

We offer a variety of insulation products for residential and commercial applications. If you have questions about insulating your home contact Whitson Insulation today.
