Get The Most From The Investment In your Roof Insulation
The usefulness of insulation and its protection properties is based on what is known as its R-Value. Insulation is manufactured to prevent the flow of heat. The more heat the insulation stops, the higher the R-Value of that insulation.
When comparing spray on insulation to fiberglass insulation, you will find that the spray foam has a much higher R-value for any given thickness. In other words, 2 inches of spray foam will insulate your roof better than 2 inches of fiberglass batts.
Cellulose fill, either blown-in or applied by hand, also has a higher R-value than fiberglass batts at the same thickness. Even though the cellulose fill it is twice what fiberglass insulation is, it still doesn’t compare to spray foam insulation which is almost twice as much as the cellulose fill at the same thickness.
R-value is truly important yes, but it is not the only factor that you want to bring into consideration when trying to choose the best insulation for your home. One of the things that can severely reduce the R-value of fiberglass and cellulose fill insulation is moisture. Just a small amount of moisture is enough to cancel out the insulating properties of fiberglass batt and cellulose.
Neither cellulose fill or fiberglass will be able to give you the 100% caverage that you really need with your insulation Although the R-values of bothe cellulose and fiberglass do not take it into consideration when rating the R-value, heat is definitely lost through these crevices. In other words, the actual R-value of installed fiberglass batt or cellulose fill roof insulation is lower than the listed R-value.
Benefits of Spray Foam Insulation
There are no adverse actions of spray foam if it gets some moisture on it. In fact, it can stop minor leaks because, when it is applied, spray foam insulation spreads to fill every gap and seal your roof. Any pollutant or other airborne irritant that could get through any of the gaps that are left with the faberglass and cellulose will be kept out completely with spray foam.
Probably the most beneficial aspect of spray foam insulation is the fact that you can get it done for around the same cost as your traditional types of insulation materials.
