Different Kinds of Loose Fill Insulation
There are three main types of loose fill insulation. Cellulose blown in insulation uses a compressor to diffuse the heat into the other parts of the attic. This type of insulation is fire retardent. The second one, fiberglass insulation, usually comes in a roll and is cut into strips that are nailed or stapled into the beams of the roof. The third one, rock wool loose fill attic insulation, uses an environmentally-friendly material that helps absorb heat.
The term R-values refers to the measurement of thermal resistance of the insulator. Ergo, the higher the R-value, the more the insulator is resistant to heat. The level of R-value you need for your home is determined by your cooling and heating system, together with the climate in your region.
Loose Fill Insulation
When you look at insulation and notice a fibrous material in it, you are looking at loose fill insulation. The fibrous material is made out of different recyclable materials, all treated to be resistant to heat.
Since the materials are all recyclable, this insulation is often considered to be an environmental-friendly one.
Cellulose Loose Fill Insulation
Cellulose loose fill insulation uses recyclable materials such as old boxes and newspapers. These materials are then reduced and pulverized, making them into the “filler” of the insulation. After that, chemicals are mixed into this composition to make it resistant to fire and pests.
Fiberglass Loose Fill Insulation
Fiberglass loose fill insulation is created when glass is melted and spun into small fibers. These small fibers serve the same purpose as the pulverized and treated boxes and newspapers in cellulose insulation.
Rock Wool Loose Fill Insulation
Rock wool loose fill insulation, also known as slag wool insulation, is similar to its fiberglass counterpart. The only difference is the fibers are not made from molten glass. Instead, molten rock is spun until it becomes a fibrous material that can be used for insulation. This type of fiber is also known as “blast furnace slag.”
