Blown In Insulation
When building a new house, batt insulation, which are thick strips of spun fiberglass, are cut to fit in between wall studs and ceiling joists before wallboard is installed to increase insulation values. It is rarely feasible to install batts in most existing homes, however, as drywall would have to be removed, which is an expensive, messy and time consuming task. Blown-in insulation can be added to attics and walls without having to worry about any of that hassle. Which is where insulation contractors of Ogden Ut come into play! We are able to come in and blow in the insulation so you have nothing to worry about. What’s even better about his type of insulation is that it can also seal small gaps and spaces as it settles, filling these spots where cold air could otherwise seep in. Not only does this create an insulation blanket, blown-in insulation also helps reduce sound transferring from the outdoors to indoors, so unwanted street noise will be softened.
There are three types of insulation that are commonly used. These include loose-fill fiberglass, cellulose, and rock wool. Each one has it’s pros and cons. The minimum suggested insulation values vary by geographic zones. The higher the thermal resistance (R-value), the greater effect the insulation has. Not every type of blown-in insulation offers the same thermal value, but in several cases, adding just a little insulation is better than nothing at all.
-Loose-fill Fiberglass: This very light insulation is made from glass that is heated to a liquid and then spun into thin fibers. When it is blown into attics and wall spaces, loose-fill fiberglass offers an average R-2.5 thermal value per inch. Remember, the higher the number, the greater the insulating effect. You would need a thickness of about 7.5 inches of insulation to equal the insulation value of a batt of R-19 insulation (which is a common batt value).
-Cellulose: For homeowners that are eco-minded, cellulose is often their insulation of choice. This is because it is made from finely shredded recycled cardboard or newspaper. This is the most common type of blown-in insulation used, and it’s also chemically treated to resist mold and fire. One downside to cellulose is that if it gets wet, it can lose its fluffiness and become soggy and compact, which reduces its R-value. Cellulose insulation has an average thermal value of R-3.7, so you would need just over five inches to equal an R-19 batt.
-Rock Wool: This type of blown-in insulation is also called “mineral wool,” which is made from blast furnace slag (combination of firing iron and iron ore). Rock wool has a thermal value of R-3.3 per inch, and is much more expensive than loose-fill fiberglass or cellulose. Regardless of its high price, due to its excellent fire resistance, rock wool is used in areas subject to fire codes, such as a connecting wall between a house and an attached garage.
