As an expert in insulation, I highly recommend removing old attic insulation before installing new cellulose insulation. This is because old fiberglass insulation can potentially harbor mold, mildew, or rodent droppings. On the other hand, cellulose insulation is made from recycled newspapers and paper bags that are treated to resist mold, fire, and insects. This pretreatment makes cellulose insulation the best alternative for your attic.
By removing old attic insulation, you are not only getting rid of potential problems but also ensuring that your home is properly heated and cooled. Over time, attic insulation can deteriorate, losing its ability to effectively regulate temperature and insulate the house. This deterioration can be caused by displacement or sedimentation of insulating materials, as well as environmental factors like excessive humidity or damage from direct sunlight. Ultimately, it is necessary to remove old insulation because it hinders airflow in the attic, promotes mold growth, and can be dirty. Since the attic is ventilated, the old floor insulation has been exposed to outside air, making it less effective. While the cost of removing attic insulation may seem high, it can make a significant difference in both your health and your home's energy efficiency.
The main benefit of removing blown insulation is that it improves air quality and eliminates pests. Rodents are known to hide in insulation, making it a common place for infestations. So if you have a problem with rodents, removing the old insulation is a must. However, if there is no water damage or signs of infestation, you may be able to get by without removing the insulation from your attic. It's important to note that the roof cover must be insulated for several reasons: to protect the roof, provide a conditioned space in the attic, and prevent drafts.
When you insulate the attic floor with spray foam, you essentially create a seal that separates it from the rest of the house. This is why it's crucial to hire experienced and reliable insulation professionals for the job. At RetroFoam of Michigan, we have over 17 years of experience insulating thousands of attics in the lower peninsula and Toledo metropolitan area. We not only specialize in removing old insulation from attics but also understand how it affects air circulation throughout the house. While pests and animal infestations can be a nuisance, they can also cause extensive damage to your attic and existing insulation.
Some may think that leaving old cellulose or fiberglass insulation in the attic floor will add extra insulation to the top floor, but this is not the case. So, is it worth it to remove old attic insulation? The answer is yes. Whether you're dealing with high utility bills, strange smells, or long-term health concerns, modern insulation can help ensure your home's comfort for years to come. We know that traditional attic floor insulation must be removed before spraying foam on the roof cover, as it can impede airflow in the house. So why should you consider removing attic insulation? Is it just another trend like installing popcorn ceilings? Or is there a logical reason behind it? In addition to natural wear and tear and environmental degradation, there are several other benefits to removing old attic insulation.
