Blown-in insulation refers to spraying or blowing insulation materials into the attic, wall cavities, and floor. The methods for insulating vary according to the type of insulation material used. Blown-in insulation delivers improved performance and less settling over time.
Blown-in insulation materials are classified as either fiberglass insulation, mineral wool insulation, or cellulose insulation. Fiberglass insulation is made of small particles of spun fiberglass fibers. Mineral wool insulation is made from small particles of steel slag or rock, both recycled manufacturing wastes. Cellulose insulation is recycled newspaper or cardboard that has been treated with chemicals to make the material flame and insect resistant.
Insulation materials are effective based on their R-value. R-value is the measurement of the insulation material’s thermal resistance. Materials with high R-values are effective barriers against heat loss. Those with low R-values are prone to heat loss, which means that they are not very effective insulators.
The R-value of insulation depends on the type of insulation material used, including the thickness and density of the material. Blown-in insulation materials have two R-values. The first one is the measure of its thermal resistance at the time of installation. The second one is the degree of thermal resistance after the blown-in material settles over time.
Blown-in materials are installed using insulation blowing machines. There are various types of machines with different load capacities. You can choose an appropriate machine based on the amount of insulation material that will be used. If you want fiberglass insulation, you will need fiberglass insulation blowers.
It is easy and economical to apply blown-in insulation in homes. This type of insulation material is perfect for hard-to-reach areas, such as stove vents, chimneys, or places in the home where there are obstacles such as protruding water pipes or electrical lines. Consult a professional in the industry to find out what is the best insulation material for your home.
