Blown Insulation

Key Advantages to Blown Insulation

Since our inception in 1972, here at 31-W Insulation, we have witnessed many innovations in home insulation products and techniques. We stay on top of the industry to provide you with the best option for your needs. Blown insulation, also called blown-in or blow-in insulation, comes in two types – fiberglass and cellulose, each with its advantages.

• Cellulose Blown Insulation – This type of blown insulation provides roughly R3.5 for each inch of product installed. It is manufactured using primarily recycled newspaper. Quite a few newspapers are needed to insulate a modestly sized home – an equivalent of what you might read over a lifetime! It might seem like using paper isn’t a wise idea because of its flammability, but it is treated chemically to make it resistant to pests and fire. It offers exceptional air-blocking efficiency with a lifespan of 20 to 30 years.
• Fiberglass Blown Insulation – This product is often chosen as the lower-cost option of the two when a small area is involved that has been sealed properly. The R-Value of this type of blown insulation is R2 per inch and has a longer lifespan of 30 to 50 years.

Both products offer a variety of advantages, including being able to reach areas where batt insulation would be impractical, such as interior walls and difficult to access attics or those with several obstructions to work around. We are always happy to discuss blown insulation and answer all your questions, so you can make an informed decision about what type of insulation fits your needs, budget, and expectations the best.
