Types of Insulation
There are four common types of insulation used in homes. While each one has its unique benefit, not every option will be perfect for your home. Use the guide below to determine which type of insulation will provide the best value, help reduce energy costs, and create an eco-friendly, efficient environment at your home.
1. Spray Foam Insulation
The easiest "hack" for insulating your home without major construction is spray foam, a chemical-based insulation that’s mixed at your home before it's applied using a special sprayer. Spray foam's ability to get into tight spaces makes it a top pick for cold climates.
2. Fiberglass Insulation
The most common insulation found in homes, fiberglass consists of extremely fine glass fibers. It comes in batts/rolls, loose fill, rigid boards, and specialized duct insulation. Fiberglass batt installation costs range from $1,000 to $2,400, but if you decide to DIY the material itself costs only $0.30 to $1.50 per square foot.
3. Cellulose Insulation
Thick and dense, cellulose is the "down feather" of the home insulation world. Cellulose is a top eco-friendly pick because it’s derived from plant sources.
Cons
Sometimes settles or packs down over time to create thermal bridges capable of transferring hot and cold air

It may be used for the full insulation or in targeted areas that are prone to moisture accumulation. If used to insulate a full attic space, it would be on the upper end of the cost spectrum for insulation with potential costs of $10,000.
What is the R value of insulation?
The R-Value is a way to gauge how effectively insulation blocks the flow of heat through it, which can keep heat inside your home on cold days and outside on hot days. On the minimally insulated end of the spectrum are R-Values below R30. For maximal insulation, you would want an R-Value closer to R60.
What is rigid board insulation made of?
More commonly used to insulate walls in living spaces than attics, rigid board insulation is made from polyisocyanurate or polyiso, extruded polystyrene (XPS) or expanded polystyrene (EPS).

How Location Affects Your Exterior Wall Insulation Needs
Insulation in your exterior walls lowers heating and cooling costs and also improves comfort. But it stands to reason that you’re not going to need the same R-values in Florida as you do in Montana or New York.
The Insulation R-Value Rule
R-values are a vital factor in terms of the efficacy of insulation, which is why the Federal Trade Commission (FTC) created the R-Value Rule. Simple in concept, it requires manufacturers, sellers, and professional installers of insulation products to disclose the R-value.
Types of Exterior Wall Insulation and R-values
So now all you have to do is match the R-value recommended for your climate with an insulation type that is suitable for exterior walls.
Final Wrap Up
The best type of insulation to use for your exterior walls will keep your home warm in winter and cool in summer.
