What is the Best Attic Insulation? [2022 Buyer's Guide]

Dec 29

As the old saying goes, there are various ways to deal with a cat's claws. The same applies to attic roof insulation. You have a myriad of options. However, choosing the correct attic insulation and the right insulation contractor for your house can determine the difference between having enough savings for a summer vacation or having to forfeit the savings you made during summer to your energy bill.

What kind of attic insulation is best?

Due to various variables like R-Value, accessibility, environmental friendliness, durability, and the ever-important factor of "bang for your buck," different types of attic insulation in Richmond, VA, have become more sought-after by homes over the years.

Here are a few of the most commonly used forms of attic insulation in Richmond, VA:

Insulation using Fiberglass Batts

The most well-known attic insulation is fiberglass, made of wonderful glass fibers created out of recyclable materials and sand that looks like cotton candy. Fiberglass insulation can be found in large, rolled-up sheets known as batts. The sheets are bonded together using a vapor barrier similar to foil reflective backing or paper.

Fiberglass Batt Insulation Benefits

Fiberglass batts provide a few advantages, particularly for constructions with attics that aren't well-insulated (as well as for renovations).

Fiberglass is not combustible, which means you can easily install it close to the wood structure of your attic.

Easy to Pick Up and Unfurl -- Batts are easy to carry around and takedown. Because of their size, they can cover lots of ground quickly. When placed in the right way, they are great for new construction.

Fiberglass Insulation Blown In

Loose-fill insulation is another option. It's made of tiny pieces which are packed together in huge sacks. These pieces are implanted using a blowing machine that spreads the fragments out to fill in the gaps.

While a study in the 1990s found that fiberglass blown into reduces its R-value when exposed at temperatures less than 20°F (which was not the case), this claim was not verified.

Fiberglass Blown In: The Final Word

If your attic meets the requirements listed below, fiberglass insulation blown may be the best choice for you:

Some insulation is pre-existing and is brittle.
The space is not evenly distributed with the Joists.
In the dirt, you will find different obstacles.
The ceiling is low. Low-clearance attics make it challenging for batts to be installed. Small crawl spaces will be sufficient for a blowing device to work.

Cellulose Blown-in

Cellulose is produced from the newspaper, broken into tiny pieces. While it's a straightforward and cost-effective alternative, cellulose is only presented in this manner due to its popularity throughout the years. Because of various reasons, blow-in cellulose is probably the worst choice for insulation. Here are some of the reasons that people believe that it's a viable alternative (but it isn't):

The Final Scoop on Cellulose Blown-in

Blown-in-cellulose can be utilized in the same ways similar to blown-in fiberglass. However, a lot of cellulose advertising has led to false statements, making it far from the ideal choice for attic insulation.

Foam Spray

There is nothing better than spray foam as an insulator. It's available in two varieties: open-cell and closed-cell, with the latter sporting an exceptional R-Value of 7! Spray foam insulation has several distinct advantages. These include:

Spray Foam expands rapidly and secures air in an enveloping closure that resembles a vault.
There is no water permitted. Foam is an anti-cellulose material in the sense of moisture. It is entirely impervious to water.
Expanding the Building Envelope Foam is an excellent material to increase the size of your building envelope in an approach that is unmatched by other insulation materials.
In addition, expanding your building's envelope using spray foam also enhances your home's structure and acts as an effective sound barrier.

Spray Foam Insulation Last Word

Spray foam is a significant factor in attic insulation. As with top players who want maximum salaries, the spray could cost you quite a bit of money. Spray foam can be difficult to install, much like other athletes. It's tough to install correctly and safely without a professional. That's why hiring a trusted insulation contractor is highly recommended.

Spray foam is an excellent insulation material that reduces airflow and leakage. This will enable you to cut down on heating bills. Spray foam is a more costly option than other insulators; however, it'll eventually pay off.
