It’s hard to calculate how much money is pouring through your roof when it comes to heating and cooling your home. Some experts have estimated those costs to be as high as 45 percent! If you don’t have insulation in your attic, it’s easy to lose about half of your heat or cooling, basically doubling your ac or heating bill. You can significantly reduce these costs just by adding insulation, which you can do yourself if you’re willing to get a bit dirty.
You will initially need to determine the type of insulation that will best suit you, then how much of it you’ll need. If you do already have some insulation, it’s not especially good to compress things like fiberglass or to put different materials on top of each other, such as cellulose (a blown in material) over fiberglass or vice versa. It is better to stick with corresponding materials; fiberglass on fiberglass, cellulose on cellulose, etc. Batts, a blanket type of insulation material, on the other hand, can be used with more batts or with loose-fill material like fiberglass.
If you do compress the loose-fill material, that will decrease the R-value of its insulating properties. R-value is the insulation rating for its ability to reduce the amount of heat that can escape through it, whether coming into or out of your home. A high R-value means that you are better insulated and saving money on you heating and cooling costs. The optimal R-value is between 38 and 49. Batts are approximately R-3 to R-3.8 per inch of thickness, loose-fill cellulose is R-3.13 to 3.7 per inch and loose-fill fiberglass is R-2.6 to R-3.0 per inch. You can find the R-value recommended for your region by going to:
After you have decided what material works best for you and how much of it you will need, you should next figure out whether or not you will need help for this project. It is best to have some help in projects like this though for safety reasons.
