Fiberglass vs Cellulose – Which Insulation Material is a Better Option

When you are thinking about getting a new insulation material, one of the most important things that you need to look at is the R-Value. So, what exactly is this R-Value and how does it matter to you? Well, R-Value is the numerical value that tells you how efficient an insulating material is when it comes to maintaining a constant temperature. The higher the R-Value, the better it would be. Now, two of the most common insulation materials are fiberglass and cellulose. So, which gives you a better option? Here, we are going to pit them against one another and see which would be right for you.  But, before we do that, let us take a look at the two materials.
