There are many types of attic insulation. The most common one are fiberglass batts, loose-fill fiberglass, spray foam, and cellulose. If you still hesitate to go with which type, you should know the difference of each type first. Here are more explanations for them.
To begin with, let’s start with the fiberglass batts. This is the easiest insulation you can choose as it is easy to find in the store and not so difficult to roll out. Meanwhile, the cellulose attic insulation is made from recycled ground up paper. It is added with boric acid to control insect as well as to perform fire resistance. You can install it by yourself. However, you need to remember you should not buy a single bag then spread it out to try spot insulation. If you are using the help from professionals, they usually give it wet spray cellulose. It adds the amount of water. The purpose is to help in controlling the dust and increasing the insulation value.
Compared to the cellulose, the loose fill fiberglass might be an inferior product. This insulation value will drop below 20 degrees. However, this issue is big news in some years ago. Since that time, manufacturers made some changes. Now, loose fill fiberglass is still growing for a better performance. However, it is not as worse as the old days.
If you are looking for the best option, you can choose the spray foam. From three other insulations, this one is the best choice you can have. This one can fill the nooks as well as crannies in a perfect way. Besides, it is also suitable as an air barrier. If you wished to have a moisture barrier, you can also choose the closed cell foam. One con from this attic insulation is that it may come with higher cost.
