Types Of Blown Insulation
Blown insulation is an effective way to insulate your home and can be made from various materials, including fiberglass, cellulose, and mineral wool. Each type has unique benefits, allowing you to choose the best option for your needs. Here are the most common types of blown insulation:
Fiberglass Insulation
Fiberglass insulation is among the most popular types of blown insulation due to its affordability and ease of use. It’s composed of tiny glass fibers spun into a material with superior thermal resistance properties. It’s ideal for attic spaces as it will fill in gaps and cracks better than other types of blown insulation.
Cellulose Insulation
Cellulose is another popular type of blown insulation due to its fire-resistant properties. It consists of recycled newspaper, cardboard, and other paper materials treated with a borate compound for added protection. This makes it an excellent choice for areas prone to fires, attics, wall cavities, and crawl spaces.
Mineral Wool Insulation
Mineral wool is highly effective blown insulation composed of spun rock or glass fibers. It’s denser than fiberglass or cellulose insulation, making it ideal for soundproofing applications. It also has superior fire-resistance qualities, making it the preferred choice in places where the flame spread is a concern. New insulation installed with mineral wool is also great at reducing energy costs.
Should You Replace Old Blown In Attic Insulation?
The answer to whether or not you should replace old blown-in attic insulation depends on the condition of your existing insulation. Replacing it may not be necessary if it is intact and still provides adequate protection from heat transfer. However, replacing your insulation with new material would be beneficial if your insulation has become matted down or is damaged. Spray foam insulation is a good option for replacing older insulation, as it can fill in any gaps and cracks better than other materials.
ย
Replacing old attic insulation can significantly improve energy efficiency and make your home more comfortable. Newer forms of blown-in insulation contain higher levels of recycled materials and better performance ratings than older insulations. Replacing old blown-in attic insulation can also help protect against mold growth by blocking moisture that collects in the attic space.
