How is cellulose insulation blown?
The cellulose is blown into the attic or walls through long, flexible tubes that run from the blower to the house. To fill walls, holes are drilled to permit access. For attics, cellulose insulation is blown parallel to the joists. It can be used on its own or blown on top of existing fiberglass batt insulation.
What type of insulation is used for blown-in insulation?
Fiberglass and cellulose fiber insulation are the most common materials used in blown-in projects. This installation technique keeps the insulation materials loose and crumbly, allowing air pockets to naturally form between the fibers. A blower machine allows the installer to place the materials precisely where they need to be.
What are the different types of cellulose insulation?
The most common type that homeowners will encounter is called loose fill cellulose insulation. This type of cellulose is contrasted by a different type of cellulose insulation that is blown onto open walls, much like spray foam.
What color is blown insulation?
Blown fiberglass comes in three common colors: white, pink or yellow and the colors simply identify the manufacturer. Blown-in fiberglass insulation in attics typically has an R-value of 2.5 per inch. The density of the blown-in fiberglass determines the R-value just like it does for a batt.

Typically, yellow insulation contains fiberglass. The resin-based binder used to hold the woven glass fibers together determines the insulation's color. To determine if the yellow insulation contains fiberglass, expose it to bright light.
Is there a difference between pink and white insulation?
After seeing a few different colors of insulation on the market, you might think the yellow, pink, white, green and brown colors carry some significance. In reality, the color of insulation typically has nothing to do with the type of material it is made out of.
Does insulation color matter?
A: Not much if at all. The color of an object does affect the absorption and reflection of incident light but insulation does not involve reflected light but is more relevant to thermal heat conduction.
Why is some insulation pink?
Owens Corning soon faced competition from other fiberglass manufacturers. The company began adding red dye to the naturally tan or yellowish insulation to distinguish it from their rivals' products. Introduced in 1956, the bright pink color became such a powerful marketing tool that the company trademarked it in 1985.
Is blown-in cellulose insulation good?

During new construction, batt insulation—thick strips of spun fiberglass or a paper-based product—is cut to fit between wall studs and ceiling joists before wallboard is put up to increase insulation values .
What is rock wool made of?
Rock Wool: Also called “mineral wool,” this type of blown-in insulation is made from blast furnace slag (a byproduct of firing iron and iron ore). The slag is heated, combined with other minerals, and then spun into an airy product that resembles the texture of raw sheep’s wool.
How to stay warm in a poorly insulated house?
Layering on sweaters is one way to stay warm in a poorly insulated house, but while you’re bundling up, your furnace is still working overtime to ward off the chill and your home’s water pipes could be at risk of freezing and breaking. Today’s building codes require a minimum amount of insulation in walls and attics, but older homes were often under-insulated, so for many owners of such homes, the answer is blown-in insulation: tiny pieces of material (think confetti) that is literally blown into your walls and above your ceiling via a long hose. Keep reading to find out if blown-in insulation might be your solution to comfier conditions and lower energy bills.
Does blown in insulation reduce thermal resistance?
After a few years, blown-in insulation tends to settle downward by a few inches, which slightly reduces its overall thermal resist ance (known as R-value), because it leaves a small section at the top of the stud space uninsulated. Blowing in additional insulation is an option, but most homeowners forego this step because it’s such a small area.
Is rock wool fire resistant?
Despite its high price point, due to its excellent fire resistance, rock wool is often called for in areas subject to fire codes , such as a connecting wall between a house and an attached garage, or in the floor between a garage and a FROG room (finished room over garage).
What is the R-Value of Cellulose Insulation?
The R-value of cellulose is between 3.2 to 3.8 per inch of thickness.
