Insulation in your home plays a vital role in keeping your energy spending low during the wintertime. If your home has insufficient insulation, you will definitely notice that you are spending a lot more than you need to on heating.
Insulation will have something called an R-value assigned that will let you know how efficiently it blocks heat transfer. It is important to understand, however, that the R-value of insulation can change depending on the state of the insulation. For example, wet insulation is not as effective as it could be, and the same is true when it comes to compressed insulation.
Another interesting thing to keep in mind when it comes to your insulation is that an entire surface could easily be compromised if just part of it is lacking insulation. Cracks and holes can cause your insulation to be much less effective than it should be. Repairing issues like that can save you a lot of money over the years.
