Traditional Batt-type Fiberglass insulation
There are many different types of insulation you can have in your home. Fiberglass insulation is one of the most common and is used by many. There are a variety of colors as well but not much difference between them and is not worth concerning yourself over having the right one. The different colors are more for trademark purposes. This insulation can be a little irritating to the eyes, throat and skin but that does not mean it is a life-threatening hazard like some are led to believe. It is made up of tiny glass shards so of course when coming in close contact it may be a little unpleasant.
Though this insulation is known for not stopping air flow, it is fire resistant due to it being fiberglass and will melt at a certain degree. It will not support moisture and Insects feel no need to bother with it due to it being organic and having no nourishment or food value for them. It helps keep your home warm during the winter months and cool during the summer months. It tends to last a lot longer than most other types of insulation. It can last up to 75-80 years or longer. It can also reduce energy costs by at least 40 percent.
Blow In Insulation
This insulation is the same material as the batt insulation, just more broken down. The difference is this one is less likely to have air flow and has better sound control. It is also energy efficient and is fire resistant. It will not produce any type of growth because it does not hold moisture. You need a machine to do this type of install as well as the proper clothing gear to protect yourself from the shards.
Spray Foam Insulation
This is a chemical compound of isocyanate and polyol resin that expands 30-60 times its original liquid form. It is a little more costly but has no room for air flow and lasts up to about 80 years. It is good for humidity control and you will not have to worry about cold air getting out during the summer, or hot air getting out during the winter or vise versa.
