Blown in Cellulose Insulation

The material used in cellulose insulation is made from different recycled materials including newspapers and cardboard. Then, boric acid and other substances are applied to the insulation fire resistant. Cellulose Insulation is blown into the attic to cover any  small gaps. One benefit of Cellulose Insulation is the eco-friendly recycled material that helps reduce waste. However, Blown-in Cellulose insulation typically performs better than fiberglass, but is still messy to install and can be a pain to maintain. Also, Cellulose also doesn’t mix well with liquid. So, mold can grow quickly thus causing problems for homeowners. Lastly, Blown-in Cellulose  is time intensive and can be a messy project for DIY homeowners.


Fiberglass Batt Insulation

Fiberglass batt insulation has many extensive benefits making it the number one choice for most homeowners. Fiberglass is considerably eco-friendly because it is created from sand which counts as a renewable energy source. Also, the vapor barrier is flame-proof and slows the spread of fire. Fiberglass batt insulation rarely shrinks or collapses, and Fiberglass Batt Insulation installment is straightforward. Many homeowners choose to complete the installation process on their own. Fiberglass batt insulation is also soundproof, and helps reduce external noise from entering the home. 

However, Fiberglass poses a health risk if inhaled or touched. Furthermore, the vapor that’s used as a barrier can be harmful. This type of insulation doesn’t mix well with condensation or moisture, potentially allowing mold to become a real problem if not properly managed. Rodents and other unwanted animals love fiberglass batt insulation, and often make their home out of the material.


Blown in Fiberglass Insulation

Blown-in Fiberglass uses the same base material (Fiberglass), but it doesn’t require the vapor. It differs based on the distribution method. Rather than being rolled up, it’s blown in through a machine. When using the blown-in method, it fills the attic better, ensuring it’s air-tight. This small switch of distribution to blown-in, can help you save on your monthly energy bill. Blown in Fiberglass fills any cracks or gaps, even in awkward spaces. The blown-in distribution method is far quicker. It takes a matter of hours to get your attic insulation up and running. With fiberglass batt insulation, however, it often takes a few days.

Blown-in fiberglass is considered to be so dangerous, it’s sold with a health risk warning label. After the insulation has settled, It needs more maintenance than other types of attic insulation. If the Blown-in insulation gets wet, removing the insulation isn’t as easy as removing Fiberglass Batts. Blown-in Fiberglass needs consistent maintenance to ensure mold or mildew does not grow.


Spray Foam Insulation 

Spray Foam Insulation offers more comfort for homeowners and their families as rooms within the home are better protected from the outside elements. A professionally completed spray foam insulation job allows for precise, long lasting coverage. Spray Foam Insulation has a longer shelf life than the typical pink Fiberglass insulation. Air leaks and improper insulation are a couple of the biggest culprits of high energy bills. Spray foam insulation creates a powerful airtight seal that is measurably less permeable to air infiltration than other types of insulation. Spray foam is not only water-resistant but it’s composed of a polymer that provides no source of food for mold or bacteria. Spray foam is engineered with an inert polymer that allows it to have an ageless lifespan. It helps reduce energy consumption within the household, and protects against moisture and mold growth. Spray Foam insulation is a bit pricier in the beginning, but it’s worth it in the long run because it’s long-lasting. Cheaper forms of insulation have to be changed out on a more frequent basis. So, the long lasting spray foam produces fewer consumed materials and is long term eco friendly.
