Atlanta's Premier Spray Foam Insulation Source
At Spray Foam of Atlanta we understand that Fiberglass is the most installed insulation in Americaq. It is composed of recycled glass and silica sand – bountiful inexpensive resources. It comes in loose form that is blown in or in large pink or yellow rolls. It is a relatively inexpensive insulation material that if installed by an expert, can save you up to 20% on your utility bills. The savings combined with the low cost make it popular with both builders and owners.

With that being said,  many fail to consider are the  drawbacks of fiberglass insulation. having fiberglass in your home raises health concerns including but not limited to toxic emission of formaldehyde and the long-term risks of breathing in its microscopic particles. However, it if it does reach a high enough temperature that it ignites, it is likely to burn fast as it melts and emit toxic fumes which can have devastating consuquences.

When it comes to energy efficiency, fiberglass falls well short of spray foam insulation. First, whether it is blown in or rolled, there will always be cracks between the material and rafters & studs - which will let the hot or cold air seep through. Not only does this decrease its effectiveness to insulate, it also does nothing to prevent moisture from seeping in and therefore will allow mold & mildew to grow in the building and on the material itself which can also have dire consequences to your health and wallet. 

Also, potential buyers should be aware that because it is a soft material, fiberglass settles and loses its volume over time. Consequently, heat’s ability to transfer through the material will increase a bit over time along with energy bills - so in other words, it isnt a long term solution.
