Insulation Materials and Types Comparison

Today we’ll be looking at an insulation materials comparison for three different types of home insulation and understanding the uses of each.

When it comes to choosing the material you want to insulate your home, there are several important factors like cost, efficiency, climate, performance, and lifespan.

Cellulose, fiberglass, mineral wool, denim, extruded polystyrene rigid foam, polyurethane spray foam, and more have some differences between them regarding their effectiveness and location of insulation needed.

How Insulation Materials Affects R-Value

It’s very important to know beforehand where you will need to install insulation and the R-Values for the area which needs to insulate. 

The main factor is called the R-Value. This is a common measurement system which indicates the resistance to heat transfer all through the home.

The higher the R-value, the better since this measurement is usually defined for a one-inch thickness of insulation. For example, if the insulation has an R-Value of 4.0 per inch, a 4-inch thick material of that insulation would have a total R-Value of R-16.

This comes from 4.0 per inch X the 4-inch material of insulation.

Reach for These Materials

Not every type of insulation can be installed by the homeowner. Fiberglass blankets are easy to install if you wear long sleeves and a mask, the other types of materials will need to be installed by a professional. 

Now, let’s go over the most common materials used for insulation. The first type is blankets which can come in batts or rolls. These can come in a material made of fiberglass, mineral wool, and plastic or natural fibers.

These are used in unfinished walls, including foundation walls. Also, floors and ceilings can use blankets to insulate. Easily installed between studs, joists, and beams, blankets are the ultimate ‘do-it-yourself’ project, as the cost is relatively lower than other methods.

Types of Insulation Materials:

Concrete Block Insulation

Next, we will take a look at concrete block insulation. Best practice is spray foam or rigid foam boards which are placed on the outside of the wall in new constructions or inside in existing homes.

Usually installed in unfinished or foundation walls, this installation method requires specialized skills. 

Foam Boards

There are also foam boards made of polystyrene or other poly-like materials which can be used almost anywhere in the home as long as there is ½-inch of gypsum board or other building-code approved material for fire safety.

This method has a relatively high insulation value for it’s smaller thickness. 

Blow-In Insulation

Next on our list of insulation materials are blown-in components. These come in variations of fiberglass, mineral wool, and (what Green Attic specializes in) cellulose insulation.

Enclosed existing walls, open wall cavities, unfinished attic floors, and other hard-to-reach places are a great place for these loose-fill materials to do their job. It is blown into place using specialized equipment, and sometimes can be poured in.

Blown-in insulation really shines when added to existing finished areas, irregularly shaped areas, and around obstructions.

3 ways to Create Attic Storage Without Compromising Insulation Performance

Green Attic typically adds 2×6 framing over the top of existing framing ( taking into account the mechanicals, pipes, conduit, and other landmines on the attic floor, a raised platform provides a smooth surface for storage. This method like some of the above methods reduces head clearance and storage space but does not compromise the insulation.

What is a Home Energy Audit? 3 Ways to Benefit

An energy audit generally consists of air leakage detection and identification, insulation evaluation, house heating system evaluation, water heating evaluation, appliance evaluation, computer and electronics evaluation, doors and windows, evaluation, lighting evaluation, personal habits, blower door test for CFM and ACH, and a summary report.

We focus on the customers concern, the reason for the call, so the general items listed on a typical audit may or may not take center stage during the audit. The homeowner relies on us to direct the conversation towards truth, fact based building science, and energy conservation.

How To Prevent Ice Dams in 3 Impactful Ways

An Icicle is simply a measuring stick of heat loss from the attic. Ice dams form when snow melts on the top, warmer part of a roof, water flows down to the colder eave overhang, where it refreezes. As the ice accumulates, it forms a blockage that prevents additional snowmelt from flowing off the roof. It can be prevented by adding insulation, proper air sealing and ventilation of the attic.
