How Much Insulation Does Your Home Need?

Insulation Contractors

When it comes to energy efficiency, nobody’s home is perfect. However, one of the most effective ways to improve your home’s energy efficiency and stay comfortable all year long is to install insulation.

As you’re getting ready to insulate your home, one of your first questions will most likely be, “How much insulation do I need?” The amount of insulation your home will need depends primarily on two factors:

  • The R-value recommended for the region you live in
  • The areas of your home that need to be insulated

Understanding these factors can help you determine what insulation is best as you schedule insulation installation for your home.

How to Determine the R-Value You Need

You may have heard of R-value for insulation, but why is it important? Understanding what R-value is and how the recommended R-value is determined are both important when insulating your home.

What is Insulation R-Value?

R-value is the measurement of a particular material’s resistance to conductive heat flow. Put simply, R-value measures how well something resists heat. The greater the heat resistance, or R-value, the greater the insulation’s effectiveness.

What R-Value Do I Need?

The R-value needed depends on the insulation’s type/material, thickness and density. Although a higher R-value generally means a more effective insulator, the highest R-value possible may not necessarily be right for your project. This can be true if the space you’re insulating already has existing levels of insulation.

Additionally, houses in certain climates don’t need as much insulation as others. For example, homeowners in Florida don’t need to worry about insulating against extremely cold temperatures—but the weather is quite different here in Wisconsin.

That’s why different regions of the United States have different recommended insulation levels. Here in the Sheboygan County area (and throughout central and southern Wisconsin), we are in zone 6.

R-Value Recommendation by Region

Recommended R-values in this region range from R5 up to R60 depending on the area being insulated.

What Areas of My Home Need Insulation?

There are several places you should consider insulating in your home, as insulation can help reduce energy costs, keep more even temperatures in your home and act as a sound barrier.

The most common areas to insulate in your home are the:

You can put new insulation over old insulation in some cases, but there are times you may need to consider insulation removal before installing new insulation.

It can be challenging to figure out where your home needs insulation removal and insulation installation, but don’t worry! An insulation professional can help you determine the areas you need insulation and their proper R-value.

Types of Insulation

When you’re deciding on insulation for your home, there are several types to choose from. Some of the most common are:

Each type of insulation has its advantages, and your insulation contractor can walk you through which type will be best for your home.

The Benefits of Each Type of Insulation:

Batts & Blown-In 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.

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.

Spray Foam

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.

Rigid Foam Board

Popular for its ability to reduce utility bills and maximize energy efficiency, rigid foam board is a great choice for insulating your office building or home.

There are three types of rigid foam board insulation:

  • Polyisocyanurate (polyiso): Polyisocyanurate rigid board insulation typically comes with reflective foil facing on both sides. This makes it ideal for the attic, as the foil helps your home reflect the sun’s energy rather than absorbing it.
  • Extruded polystyrene (XPS): Extruded polystyrene rigid board panels have smooth, plastic surfaces and are extremely durable.
  • Expanded polystyrene (EPS): EPS rigid board insulation can be used for both new construction projects and re-insulating.
