The Ultimate Guide to Cellulose Insulation: Efficiency, Benefits, and Installation Process


Arctic Insulation Contractors • April 21, 2025

Cellulose insulation has long been a trusted solution for homeowners looking to increase their home’s energy efficiency and comfort, all while making an eco-friendly choice. Unlike traditional fiberglass insulation, cellulose is made from recycled materials, such as newspaper and other cellulose fibers, making it an ideal option for those who care about sustainability and green building practices.


In this guide, we’ll take a deeper look at what makes cellulose insulation an exceptional choice for your home and explore how it can improve energy performance, comfort, and even your health.

What Is Cellulose Insulation?

Cellulose insulation is a loose-fill material that’s made from recycled paper products, typically shredded newspaper. It’s treated with fire retardants, making it both safe and durable for use in various applications around your home, such as attics, walls, and crawl spaces.


This eco-friendly option provides excellent thermal resistance, making it one of the most efficient insulation materials available today. It can be blown or pumped into place, which allows it to fill even the hardest-to-reach areas without disrupting your home.

Key Benefits of Cellulose Insulation

1. Excellent Thermal Insulation

Cellulose insulation’s dense fibers are packed tightly, offering high R-values (thermal resistance) per inch of material. This means it works harder to stop heat from escaping your home during the winter and keeps your space cool in the summer. This can significantly reduce your heating and cooling costs.

2. Sustainable and Eco-Friendly

Because cellulose is made primarily from recycled paper and cardboard, it’s one of the greenest insulation materials available. Using cellulose insulation in your home can reduce the amount of waste in landfills, helping you reduce your environmental impact.

3. Noise Reduction

Cellulose insulation has a high density, making it a great sound barrier. It absorbs noise from inside and outside your home, making it a great solution for bedrooms, home offices, or any room where you need peace and quiet. This can be especially useful for homes in busy neighborhoods or with multiple floors.

4. Moisture Control and Mold Resistance

One of cellulose insulation’s lesser-known advantages is its ability to resist moisture. It is treated with a fire retardant and anti-microbial agents, which help it resist mold growth. This makes it an ideal choice for areas prone to humidity, such as basements and attics, where moisture can lead to mold or mildew problems.

5. Fire Resistant

Cellulose insulation is treated with a fire-retardant chemical, making it safer than some other insulation materials. While no insulation is completely fireproof, cellulose’s fire-resistant properties provide an added layer of protection against fire hazards in your home.

How Cellulose Insulation Is Installed

While fiberglass insulation is typically installed in batt form or as loose-fill, cellulose insulation is usually installed as a loose-fill material. This means that it is blown into spaces by professionals, filling all gaps and cracks, ensuring maximum coverage and thermal performance.

The Step-by-Step Installation Process

We begin by conducting a comprehensive inspection of your home to identify the areas that would benefit from fiberglass insulation. We assess your attic, walls, and other spaces to determine the best placement for the insulation, ensuring maximum energy efficiency and comfort.

Step 1: Initial Home Evaluation

Our team of experts begins by assessing your home’s insulation needs. We’ll inspect the areas that could benefit most from cellulose insulation, such as attics, walls, and crawl spaces, and determine the best approach for installation.

Step 2: Preparation

Once we’ve identified the areas to be insulated, we prepare the space by sealing any gaps, cracks, or leaks. Proper preparation ensures that the insulation works efficiently and prevents air leaks that could reduce its effectiveness.

Step 3: Blown-In Application

We use specialized equipment to blow loose-fill cellulose insulation into the targeted areas. The insulation is applied evenly, filling every corner, gap, and void to ensure a comprehensive and energy-efficient solution.

Step 4: Post-Installation Inspection

Once the cellulose is in place, we perform a final inspection to ensure complete coverage and no gaps remain. This guarantees that your home benefits from the full energy efficiency of the cellulose insulation.
