Loose-fill cellulose insulation also known as blown-in insulation and is one of the most common attic insulation types. Blown-in insulation mainly refers to cellulose material that is blown into the attic to fill up empty spaces and wall cavities to achieve thermal insulation. This is a cost-effective insulation method that covers cavities in attic floors and slows down the transmission of heat and cold in your house. Cellulose insulation can be derived from plant sources but for commercial insulation purposes, it is used in the form of wood or paper-based products such as recycled newspapers, cardboard, or other consumer waste paper products.
Cellulose insulation is by far the most environmentally friendly insulation option available in the market that is also cost-effective. It is made from waste paper products that would otherwise emit harmful gasses when disposed of in landfills. When treated with boric acid, it becomes safe for installation in homes and minimizes the release of harmful toxins.
Cellulose insulation is made up of about 80-85% recycled newspapers which are passed through borate treatment to make them fire-resistant. However, despite the high fire safety rating, it is not a fire-proof insulation option.
One of the most common mistakes that can occur as a result of poor cellulose insulation is only filling the walls up partially with cellulose. This can happen when the holes are not drilled strategically or drilled too low in the walls and the insulation does not reach all the nooks and corners of the attic.
Another common mistake that insulation installers make is not filling insulation in air leaks around ducts, wires, and pipes. No gaps should be left while applying cellulose insulation otherwise there will be breaks in the thermal barrier.
Blown-in insulation lasts for about 20-30 years depending on the insulation material that is used. Fiberglass insulation may last for a longer time because it is made of plastic which does not degrade easily. Cellulose insulation is composed of recycled natural materials such as paper so it can last for up to 2-3 decades.
Due to its higher thermal resistance, blown-in cellulose insulation is the best insulation option for homes. Not only does it help you remain energy efficient but it is also the most green-friendly and budget-friendly solution when it comes to blown-in insulation.
Cellulose insulation prevents the growth of mold by creating a tight air barrier that cuts off the main moisture source that mold needs to thrive on. Borate treatment is also applied to cellulose making the insulation resistant to mold growth.
Rodents cannot nest in cellulose insulation because there is no space for them to burrow and make a nest. If they try to nest in cellulose insulation, it collapses on them. Therefore, you will not have to worry about pests infestation with cellulose insulation.
To the untrained eye, the spray foam application process appears deceivingly simple. Just spray on the insulating foam. Let it cure. Cover with sheetrock. Job well done. Or is it? As a pioneering force in the field of spray foam insulation for well over two decades, AirSeal Insulation Systems knows that the analysis, planning and strategy surrounding a building envelope will directly affect the outcome of every job. The understanding of structural design, material application, modern technology and environmental factors all contribute to the effectiveness of an air barrier system. In other words? There’s a serious process involved, and it’s something we make a big deal about.
