Top 5 Insulation Options For New Homes

Fiber Insulation Options


Cellulose Insulation

Cellulose insulation is mode out of fluffed and shredded newspaper. It contains 15% environmentally safe fire retardant mineral compounds and 85% recycled material. Cellulose can be sprayed on wet or Blown-in dry. It costs about the same as fiberglass but has a higher R-value.

Cellulose R-Value: Cellulose Insulation has an R-value of 3.5 per inch average

Cotton Insulation

Cotton insulation has R-value of 3-4 per inch covered while fiberglass insulation has R-values in the 5-6 per inch range. Cotton insulation isn’t as effective as fiberglass and you will pay 15-20% more to install it. Although, most homeowners who are in to green building are more likely to install cotton because it’s more of an environmental friendly type of insulation material.

Cotton R-Value: Cotton Insulation has an R-value of 3.5 per inch average

Fiberglass Insulation

Fiberglass does have some benefits versus other types of insulation methods. Fiberglass insulation is one of the cheapest insulation methods to install and is pretty easy for just about anyone to do. Any half-way handy man can install fiberglass insulation. Although, most insulation contractors do not recommend fiberglass insulation anymore, most are turning to spray foam and foam board applications.

Fiberglass R-Value: Fiberglass Insulation has an R-value of 4.2 per inch average

Sheep’s Wool Insulation

Wool insulation is exactly as it sounds, make out of sheep wool or fibers. Many business owners and homeowners install wool to insulate their home or business. Although, wool insulation is made for colder climates, desert climates like Phoenix, Arizona call for a different type of insulation that more resistant to heat rather than keeping it all in.

Wool R-Value: Wool Insulation has an R-value of 3.7-4.2 per inch.

Non-Fiberglass Insulation


Soy Based

There are only 2 types of insulation that will fill all the cracks you need to fill, spray foam insulation and soy based spray foam insulation. Soy-based spray foam is actually better for installation because it fills even more tiny spaces than traditional spray foam does and is a biodegradable/renewable resource that’s also great for green construction.

Soy-Foam R-Value: Soy-Based Insulation has an R-value of 3.6 per inch average

Spray Foam Insulation Options


Open-Cell Spray Foam

Open-Cell spray foam insulation is the cheapest spray foam option. It’s called open cell because the internal foam bubbles never close completely. When the foam starts to expand, the air becomes trapped in the bubbles. This creates billions of air pockets in the foam that slow heat down as it passes through the bubbles.

Open-Cell R-Value: As fancy as it sounds, open-cell spray foam Insulation has an R-value of 3.5 per inch.

Closed-Cell Spray Foam

Closed-cell is the best type of spray foam because it’s much stronger and denser than open-cell. Also it doesn’t allow air to pass through or water to be absorbed. This barrier is created by the closed bubbles that are filled with gas to make them a better insulator and smaller.

Closed-Cell R-Value: Closed-cell spray foam Insulation has an R-value of 7 per inch.

Foam Board Insulation Options


Expanded Polystyrene

Expanded polystyrene is the best insulation of all three types of rigid insulation. This type of insulation is typically used for Wall, Roof and structural applications. This insulation can be treated to resist pests and doesn’t retain water. Expanded polystyrene is less likely to degrade overtime versus other types of insulation.

Expanded Polystyrene R-Value: Expanded Polystyrene Insulation has an R-value of 4.6 per inch.

Extruded Polystyrene

Extruded polystyrene is recognizable mostly by their pink, green or blue colors. They take 2nd place vs other type of foam board insulation in both R-value and cost. This type of insulation is more likely to absorb moister overtime and doesn’t come with any warranties on R-value retention.

Extruded Polystyrene R-Value: Extruded Polystyrene Insulation has an R-value of 5 per inch.


Polyisocyanurate is commonly used in different roofing applications. Although, these panels are expensive to buy but have a higher R-value that comes with the higher price. However, these panels are not made with environmentally friendly process and cannot be recycled.

Polyisocyanurate R-Value: Extruded Polystyrene Insulation has an R-value of 6.5-8 per inch.

SuperReflex R-Value: SuperReflex is an insulation all in itself, it’s not even rated with R-value. It is rated with an E Value. E-Value Stands for Emissivity of heat. R-Value stands for Resistance to heat. An easy way to think about it is using sweaters. If you wear a sweater in the cold weather that sweater has an R-Value and depending on how thick the sweater is will determine how warm you will be. In the summer, In order to block the heat however you will need something that does not retain heat at all like insulation does. The best product that does not retain any heat, it is the lowest heat “emitting” surface in the world, with an E-Value of 0.02, which is literally impossible to heat up unless you hold a flame to it, SuperReflex.
