Is fiberglass insulation good for attic?
Although foil insulation is recommended, there is no “right” type of attic insulation. Fiberglass insulation effectively stops heat transfer into a colder area (heat leaking out of your warm house into the cold winter air!).
Is blown in fiberglass insulation safe to breathe?
Safely handling fiberglass When fiberglass insulation is moved or disturbed, it releases tiny particles into the air. If they get on bare skin they can lodge into pores and cause itching, rashes, or irritations. If they are inhaled, they can result in coughing, nosebleeds, and/or respiratory problems.
Is blown in attic insulation worth it?
Unless your home is relatively new, you will almost certainly benefit from installing blown insulation in your attic. It will make your home a more comfortable place to be in summer and winter, decrease the cost of your energy bills, and increase the value of your home.
How much blown insulation should be in the attic?
The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
Is blown insulation better than batt?
In short, there is less chance of error with blown insulation as compared to batts. Finally, while blown insulation is much more consistent and has a much lower chance of failure, the R-value of this insulation will typically have a higher R-value due to installation quality differences.
How bad is blown insulation breathing?
Fiberglass insulation has the same effect on our lungs, skin, and eyes. The area exposed to fiberglass becomes itchy and irritated. If these small particles of glass become lodged in the lungs, serious respiratory conditions may result (Green Build).
Is it bad to inhale blown-in insulation?
Yes, it is VERY bad to breathe in the insulation particles. If you breathe in enough you can have difficultly breathing as the particles attach to your lungs (your symptoms). From what I’ve heard the difficulty breathing is temporary and should not cause an infection. But it may be worth a call to your doctor.
How much does it cost to insulate a 2000 sq ft attic?

How much does it cost to blow in insulation?
Blown-In Insulation Cost Per Square Foot. Pre-installation prices for the most common types of blown-in insulation are $0.83 per square foot for Cellulose, and $0.91 per square foot for Fiberglass.
How good is blown insulation?
Blown-In Insulation is More Efficient. One of the benefits of blown-in insulation when compared to types like fiberglass batts, is that blown-in insulation is more efficient. Because loose-fill insulation is a monolithic layer of insulation without seams like are found in batts, studies have shown that loose-fill insulation performs up to 22% better than batts of the same R value .
What are the types of blown insulation?
There are three general types of blown insulation materials currently available: fiberglass, cellulose and rock wool. Fiberglass loose-fill insulation is made glass and sand that are spun or “blown” into fibers.
What materials are used in attic insulation?
Batt insulation comes in rolls, or batts, and is the most common type of insulation. It is generally made of flexible fiber or fiberglass, but other materials are available. Fiberglass batts are usually preferable for attic insulation.
