What is Cellulose Insulation?

Cellulose insulation is made from recycled paper products, primarily newsprint, and is one of the most eco-friendly insulation options available. Treated with non-toxic borate compounds, it gains fire, pest, and mold resistance.

Cellulose insulation can be installed in various ways, including loose-fill and dense-pack applications. Proper installation ensures maximum performance and longevity. Unlike fiberglass, cellulose does not settle as much over time, maintaining its insulating properties for decades. 

Why Choose Cellulose Insulation?

Cellulose insulation is an eco-friendly, energy-efficient, and sustainable choice for your home. Made from recycled materials, it provides excellent thermal performance, reducing energy costs and enhancing comfort. Its soundproofing qualities and resistance to pests and fire make it a superior option to traditional insulation materials. We use high-quality materials and the latest techniques to ensure your home is well-insulated and energy-efficient. 


Cellulose insulation comprises up to 85% recycled materials, making it a highly sustainable option. It reduces waste and repurposes paper that would otherwise end up in landfills.

Thermal Performance

Cellulose provides excellent thermal insulation, with an R-value of about 3.5 to 3.7 per inch. This helps maintain consistent indoor temperatures, reducing energy consumption and costs.

Sound Insulation

Due to its dense composition, cellulose effectively reduces noise transmission between rooms, enhancing acoustic comfort in your home.

Fire Resistance

The borate treatment not only deters pests but also significantly enhances fire resistance. In fact, cellulose can slow the spread of fire, giving more time for evacuation and reducing damage.

Air Sealing

When properly installed, cellulose can fill gaps and crevices better than other insulation types, minimizing air leaks and improving overall energy efficiency.

Frequently Asked Questions

What are the benefits of cellulose insulation?

Cellulose insulation offers superior thermal performance, helping to keep your home warm in the winter and cool in the summer. This can significantly reduce your energy bills. Additionally, it provides excellent soundproofing, making your home quieter and more comfortable. Made from recycled materials, cellulose insulation is an eco-friendly option that helps reduce waste. It is also treated to be fire-resistant, providing added safety, and pest-resistant, preventing insects and rodents from nesting in your insulation. 

How does cellulose insulation compare to fiberglass and foam?

Cellulose insulation is more eco-friendly than fiberglass and foam, as it is made from recycled paper products. It offers better soundproofing than fiberglass, making it ideal for noise reduction. While foam insulation provides the best thermal performance, it is less environmentally friendly and can be more expensive. Fiberglass is durable and moisture-resistant but can be less effective in soundproofing and can irritate the skin during installation. Each type has its advantages, and the best choice depends on your specific needs and priorities.

Can cellulose insulation be installed in existing homes?

Yes, cellulose insulation can be retrofitted into existing homes. This process involves blowing the insulation into wall cavities, attics, and other spaces using specialized equipment. This method ensures that the insulation fills all gaps and voids, providing a comprehensive thermal barrier. Retrofitting cellulose insulation can significantly improve your home’s energy efficiency and comfort without the need for major renovations.

How long does cellulose insulation last?

Cellulose insulation can last for many decades if properly installed and maintained. Unlike some other types of insulation, it doesn’t settle significantly over time, maintaining its effectiveness. Regular inspections and maintenance can help ensure that it continues to perform well and provides lasting benefits for your home.

Is cellulose insulation safe for my home?

Yes, cellulose insulation is safe for use in homes. It is treated with non-toxic fire retardants to enhance its resistance to fire. Additionally, it does not contain harmful chemicals or fibers that can cause respiratory issues, unlike some other insulation materials. Its eco-friendly composition also means it has a lower environmental impact, making it a safe and sustainable choice for homeowners.
