All You Need to Know About Types of Insulation?


Having proper insulation in your home can help you save money on energy while also regulating your home’s temperature. So if you’re seeking the most incredible wall insulation for your home, you’ve come to the right place. You can find the best wall insulation here:

Insulation Materials

Your home’s insulation can be made using different materials. Given below are the common materials:

Fiberglass: Fiberglass insulation is made using fine glass fibers. It can be used in roll, batts, and loose-fill insulation. Fiberglass is a lung and skin irritant, so it is advised to wear eyewear, masks, gloves, and other protective gear when working with it. 


Cellulose: It is made using recycled paper products. Sometimes, manufacturers will also mix borate with cellulose to make it fire and insect-resistant. Cellulose insulation is commonly used in loose-fill insulation.


Foam: Foam insulation can be polyisocyanurate, polystyrene, or polyurethane. You can even get cement-based foam insulation. Foam insulation can be installed in rigid foamboards or sprayed on your walls.


Mineral Wool: It refers to either slag wool or rock wool. Rock wool is made from a combination of various natural minerals. Slag wool is produced using waste products of molten metal known as slag. Mineral wool is naturally fire-resistant and comes as rolls, batts, and loose-fill.


Natural Fibers: Insulation is also made using raw materials like sheep’s wool, cotton, hemp, and straw. These materials are recycled from various sources and are mold, fire, and insect resistant.

Types of Insulation

There are various types of insulation available today. Given below are the most common types of insulation that you can use for your home:

Blanket: Batt and Roll Insulation

Blanket insulation is the most commonly used insulation. It comes as pre-cut sections and rolls. It is made of flexible fibers, like fiberglass, reclaimed cellulose material, natural fibers like sheep’s wool, plastic fibers, and rock wool. This insulation type has R-values ranging from R-2.9 to R-3.8 for every inch. High-density batts can also have an R-value as high as R-4.3 per inch. Given below are features of the batt and roll insulation:


● It can be used for floors, unfinished walls, and ceilings.

● It is easy to handle 

● It is installed in pieces

● It is available with or without aluminum foil or paper facing.


Spray Foam Insulation

Spray foam insulation can help seal gaps and leaks in your existing walls. First, you need to spray the liquid polyurethane in the insulation into the wall’s cavity. The insulation will then expand and become solid. Spray foam insulation comes in two types – open-cell foam and closed-cell foam. The closed-cell foam has the highest R-value per inch, while the R-values for the open-cell foam insulation are around R-3.7 per inch of thickness. Here are some features of spray foam insulation:

● It is ideal for areas of your home that are hard to reach. 

● Ideal for sealing areas around windows, doors, and vents

● Sets quickly and can be stained, painted, or trimmed

● Ideal for colder climates

● It can be more expensive than other insulation types.

Foam Board Insulation

Foam board insulation is ideal for unfinished walls, ceilings, floors, and an unvented low-slope roof. They help reduce the heat conducted through wall studs, wood, and other elements. It can be used for both exterior and interior walls. Given below are some of their features:

● R-value ranges from R-4 to R-6.5 per inch of thickness.

● Made of polyurethane, polystyrene, or polyisocyanurate. 

● It helps reduce energy consumption

Radiant Barriers

Radiant or reflective barriers, commonly known, work differently from other insulation. R-values do not measure their effectiveness. The insulation is made with a reflective barrier like aluminum foil. Below are some of the features of reflective insulation:

● Ideal for unfinished walls, attics, floors, ceilings, and attached garages 

● Reflects heat away instead of reducing it

Blown-In Insulation

Also known as loose-fill insulation, blown insulation is sprayed or blown into a place using insulation blowing machines. You can rent these machines to install this insulation. Features of this insulation include:

● Ideal for attics and oddly shaped areas of the house

● Made of cellulose, fiberglass, or mineral wool

● Can fill cavities in the wall

● R-values range between R-2.2 and R-3.8, depending on the material

Insulation is essential for keeping your home at a comfortable temperature and conserving energy. While it may appear that installing insulation yourself is simple, there are some risks associated. However, you can get your home’s insulation installed by a firm like Clean Air Doctors. They provide professional wall insulation services at reasonable rates.
