Why is it better to use blown-in insulation for your home.

When you think of it, rolling batts, fiberglass, and any other insulation done during the construction of your home are excellent. However, you might not have thought of that far during the installation. On the other hand, as I did, you might buy a home with no insulation. So, how do you get back to the drawing board and start planning for installing an insulating layer in your home? Well, I bear great news with the blow-in insulation technology. You no longer have to worry about retrofitting insulation as they offer the perfect solution. With the help of some highly qualified professionals, I was able to add insulation in my home. Additionally, it was at low costs. Hence, I can recommend it to anyone.

Here are a few things to help you understand blow-in insulation better:

Why blow-in insulation?

Insulation to your home is the first thing to come to when you think of fiberglass insulation in either faced batts or unfaced rolls. This might be because they are cheap and easy to install. In simple terms met batts are sheets of fiberglass insulation already cut into dimensions while unfaced rolls are the more extended version of faced batts. This type of insulation, however, has its shortcoming, especially when it is time to renovate your house or repair some old part of your home. It is, therefore, wise to consider blown-in insulation as an alternative to faced batts or unfaced rolls. Also, it has a higher R-value to the faced batts and unfaced rolls.

What is a blow-in insulation?

Blow in refers to the process of filling holes and attic floors with loose material. This free material has a high R-value. This free material range from open-cell spray foam to fiberglass and finally to the most commonly used material, cellulose. The cellulose blow-in the material used for insulation undergoes a process that not only makes it flame resistant but also mold resistant. It is mainly from recycled denim or recycled paper fiber. Other materials such as boric acid or ammonium sulfate are added to make it fire-resistant.

What materials do you use?

The blow-in insulation again goes an extra mile to make sure it recycles readily available materials. Whether it is the newspaper, cardboard, or other wood-based materials, you can easily find your blow-in material. All you need to do is treat it with some boric acid and some chemicals to make flame resistant. Also, by addressing the insulation material, you protect it from mold infestation.

How is it applied?

As the name suggests, it involves blowing the material to cover the whole area to be insulated. You will require an insulation blower for this job. It takes up chunks of cellulose loosens it up, and finally, it is blown through a pipe to the desired or required point. These machines are, however, costly to buy and own. Luckily you can rent one and return it once you finish the job. It is also highly advisable to let a contractor do this work as they know best how to deal with home insulation. This method is the most recommended when it comes to insulation existing homes be it cracked walls or the attic; this method will not fail

Imagine how the attic hatch is small. Now, try imagining how much work it would be to carry unfaced rolls of fiberglass insulation to the attic. Try to cover the whole attic to form one uninterrupted blanket over it. This would be a very tedious job and one that can easily be avoided by the use of blow-in insulation. A professional will finish the job within no time with just an insulation blower and a pipe. Also, it forms a very thick uninterrupted blanket insulation.

The R-value is much higher compared to the other methods of insulation that is adjustable to the desired value. When it comes to holes in the wall, the only reasonable solution is blown-in cellulose insulation. By drilling two holes on the wall in each wall cavity on the top. Drill a small distance from the ceiling and on the bottom a short distance from the floor. Then, using an insulation blower, this forces the loose cellulose into the wall cavity.
