By now, you are probably pretty well insulated against our bad jokes, but we are going to press on none the less, providing warming humor and cold hard facts about insulation. As you can already tell, there is a startling amount of variety when it comes to different types of insulation. In our last post we talked about different types of batts and blankets, which are popular because they are easy to install and even easier to transport. However, batts and blankets do not fit every need, so on we go, learning about more types of insulation.
What better place to start comparing blanket insulation and loose-fill insulation than by look at the names of the two eponymous products. As you already learned, blanket insulation comes in the form of large rolled-up blankets. This makes it easy to transport and relatively simple to install. All you have to do is roll it out, cut the shapes you need, and secure it in place. Loose-fill insulation is quite different.
Loose-fill insulation, as its name implies, takes the form of fluffy, almost cotton candy-like strands of fiber that must be blown into an attic or similar location using a specialize machine. The biggest advantage of loose-full insulation is that it can be used to seal and insulate difficult to reach nooks, crannies, and corners to eliminate problematic cold spots and energy leaks. The two primary types of loose-full insulation are cellulose, and fiberglass.
Fiberglass is extremely lightweight, and is ideal for use in ceiling or attics. One disadvantage of fiberglass is that it is so light and fluffy that is usually needs to be accompanied by blanket insulation to make it effective in very cold temperatures.
Cellulose insulation is more heavy duty, and thus more effective at extreme temperatures. However, it is too heavy for us in most attics.
