Believe it or not, your home’s attic serves a larger role than simply providing a place for you to store stuff, it also provides a barrier between your home and the cold, heat, and humidity outside. However, in order for your attic to properly protect your home, it must be properly insulated. The fact is that many home’s attics are under-insulated, or have never been insulated at all, compromising the comfort, safety, and energy-efficiency of these homes. Thusly, one of the best investments you can make in your home is to have your attic insulated. While there are several options available for attic insulation, perhaps the best option is blown fiberglass insulation. If you believe your attic may be under-insulated, here are just a few of the benefits blown fiberglass insulation could bring to your home.



Energy Star-1.pngOne of the greatest benefits of adding insulation to your attic is that this can greatly increase your home’s energy-efficiency by preventing the hot/cold air outside from penetrating your home. This can help to keep you and your family more comfortable year-round no matter what the weather outside is like. Blown fiberglass insulation does a particularly good job at increasing a home’s energy-efficiency as it is more airtight than standard rolled batt insulation. Unlike rolled batting, blown insulation is smaller and able to fill in tiny cracks and crevices throughout your attic where air typically leaks through, creating a superior seal.

Prolong The Life of Your HVAC System

Not only will blown insulation in your attic help to keep you and your family more comfortable, but by helping to keep the temperature in your home more stable, this also means that your heating and cooling system won’t have to work as hard to keep your home comfortable. This will result in less wear and tear on your HVAC system, helping to prolong its life. Additionally, since your system will not have to work as hard to heat and cool your home, this can mean significant savings on your energy bills. In fact, having your attic properly insulated can reduce the cost of heating and cooling your home by as much as 30%, making insulating your attic a wise investment that will easily pay for itself over time.


Noise Reduction

Due to its superior airtight seal, blown fiberglass insulation is also great at preventing noise from penetrating, or traveling throughout, your home. If you have neighbors who like to throw parties at all hours of the night, or you are tired of the pounding rain and crashing thunder outside sounding as though it is coming from within your home, adding insulation to your attic can go a long way in keeping these noises out. Conversely, if you like to make noise at all hours of the night, you have a screaming baby, or you have a loud dog, additional insulation can help to prevent you from having to worry about bothering your neighbors. Compared to other types of insulation, blown fiberglass insulation is particularly good at preventing the transfer of sound in a home.


Easy Installation

Another great benefit of loose-fill blown fiberglass insulation is that this insulation takes a fraction of the time to install compared to rolled batt insulation. Traditional insulation requires hours of kneeling on the floor cutting, placing, and securing sections of insulation. Instead, as the name implies, blown fiberglass insulation is simply blown out of a hose into your attic where it creates a seamless thermal protective layer of insulation throughout your attic. With blown fiberglass insulation, your attic will be insulated and ready to protect your home in a matter of hours rather than days.


Improve Indoor Air Quality

Blown fiberglass is also a good option for those who suffer from allergy symptoms, as this insulation does not contain any chemicals or additives that could irritate a person’s allergies. Further helping allergy sufferers is the fact that blown insulation creates a barrier that can prevent pollutants, pollens, and airborne toxins from entering your home due to air leaks caused by poor insulation. A properly insulated attic can prevent these irritants from entering, and spreading throughout, your home, which can greatly increase the air quality in your home. New insulation will also remove pollutants that may be lingering in your home’s current insulation if you live in an older home.

Prevent Moisture Damage

Properly insulating your attic can also prevent the damage to your home that can be caused over time by heat and moisture. Attic insulation prevents water vapor from seeping into your home and damaging your walls, which can compromise your home’s overall structure. Proper insulation can also prevent rising heat from building up in your attic, which can cause your roof’s shingles to swell and crack, which can cause costly damage. Insulation also prevents this rising heat from creating ice dams on your roof when melting snow refreezes on your roof’s edge. Blown insulation is also moisture resistant, meaning that it can also prevent mold from seeping into your home, making it vital that a home in any climate have proper insulation.


Improve Fire Resistance

An additional benefit of blown fiberglass insulation is that this airtight material is excellent at reducing your home’s risk of fires. As we previously mentioned, blown insulation is able to fill in all available space creating a much better airtight seal than traditional insulation. This helps to prevent air from flowing through small spaces fueling the flames above or below the insulation during a fire. Adding this insulation to your attic can then improve your home’s fire resistance.


While there are many benefits that adding proper insulation to your attic can provide you with, it is important that you choose the right type of insulation. Blown fiberglass insulation will create the best seal in your attic helping to keep your home comfortable and protected. Additionally, this insulation will also help to keep your energy bills in check. Contact us to learn more about attic insulation and the options that are available for your home.
