Blow-In Cellulose Insulation

Any kind of cellular plant source can be used to create blown-in cellulose insulation, which is used in both residential and commercial buildings. Wood and specialized recycled paper materials, such as newspaper, cardboard, office paper, and other paper goods, are typically used to make cellulose insulation. Although this insulation is clumpy and dense, it can fit in tight spaces and conform to ductwork and pipes since it is formed of hundreds of recycled bits of cellulose.

Since cellulose insulation is created almost entirely from recycled paper and wood products, it is acceptable for most green building certifications. The material can be handled safely and comfortably, and because it can more thoroughly insulate every square inch of the desired space, the R-value is consistently maintained.

Pros and Cons

Advantages of Blown-In Cellulose Insulation

The capacity of blown-in cellulose insulation to settle and mold around whatever shape or obstruction it encounters in your walls or attics is by far its greatest benefit. Injecting loose-fill insulation is actually one of the only techniques to add insulation to finished walls. The other option is to completely remove the drywall, add insulation, and then replace it. This procedure may be expensive.

Comparatively speaking, cellulose insulation is also less expensive than other types of insulation, yet it still has a very high R-value. An indicator of insulating power is the R-value; the higher the R-value, the better the insulation.

The utilization of recycled paper and wood products makes cellulose insulation an environmentally beneficial substitute for fiberglass and other types of insulation, and thus makes it compliant with the majority of green building certification requirements. While cellulose insulation is benign and naturally degrades, fiberglass insulation is also known to irritate and can be hazardous to breathe in.

Disadvantages of Blown-In Cellulose Insulation

The fact that cellulose can adapt to any form or space might be an issue because the insulation can pack down more readily than other types of insulation. Insulation may create holes at the top of spaces as it settles or compacts or its effectiveness may be diminished.

Another significant drawback of cellulose insulation is that it takes a very long time to dry out after absorbing any and all moisture in enclosed, insulated spaces. This dampness could result in issues with mould and mildew. Wet insulation can be far less efficient and will have a significantly lower R-value. In environments with high humidity and inadequately sealed areas, this might be an issue.

Blown-In Cellulose vs. Other Types of Insulation​

One of the few possibilities for insulating already-closed-off walls without undergoing complete refurbishment is blown-in cellulose insulation. Even though blown-in insulation still needs to be patched and painted, installing roll or batt insulation is unquestionably lot simpler than completely removing drywall.

Other types of insulation could be preferred when dealing with open (unfinished) walls. These could include fiberglass batts or fiberglass roll insulation. Given the numerous barriers and difficult-to-reach regions in attics, blown-in cellulose is one of the finest solutions. Blown-in insulation and batt insulation are frequently combined in attics to give homes a more comprehensive and efficient insulated barrier.
