ENERGY STAR certified insulation with the added value of pest control
All About CleanFiber Insulation
CleanFiber Insulation is a modern, eco-friendly insulation made from recycled cardboard instead of old newspapers. It's designed to be safer, cleaner, and easier to install than traditional cellulose insulation. Unlike other products that can be dusty and full of debris, CleanFiber uses a special process that mixes in fire-retardant materials directly during production—resulting in low dust and consistent quality.
CleanFiber Benefits
- Clean & Dust-Free - Produced using a patented "wet" process that uniformly infuses fire-retardant directly into the fibers—eliminating the dusty solid additives common in other cellulose brands.
- Acoustic Performance - CleanFiber Installation forms a dense, soft blanket in your attic, minimizing external noise and creating a quieter, more serene indoor environment.
- Fire and Pest Protection - CleanFiber is treated with borate during production, which not only meets strict fire safety standards but also helps repel mold and pests—offering built-in protection for your home.

CleanFiber Insulation Questions Answered
We have the answers to some of the most frequently asked questions.
What is CleanFiber Insulation?
CleanFiber is a clean, high-quality cellulose insulation made from recycled cardboard using a proprietary wet-process infusion. It delivers low dust, excellent fire safety, energy savings, and carbon-negative impact, all while maintaining a stable supply and competitive pricing.
Is CleanFiber Insulation a fire hazard?
No! CleanFiber contains a fire retardant that prevents the product from burning. It meets and is tested in accordance with strict federal fire safety standards. When a flame is introduced to the product, it forms a charred surface barrier that actually limits the spread of fire.
What is CleanFiber Insulation made of?
CleanFiber is made from 100% recycled corrugated cardboard—the same sturdy material used in shipping boxes. Unlike traditional cellulose insulation, which is typically made from old newspapers, CleanFiber uses this cleaner and more consistent feedstock to ensure higher quality and fewer contaminants.
During production, a patented wet process is used to separate the cardboard fibers and infuse them with borate-based fire retardants. This not only improves fire safety but also helps deter pests and mold, all while producing very little dust.
How does CleanFiber Insulation help with pest control?
CleanFiber Insulation is treated with borate, a natural mineral compound known for its effectiveness against common household pests. When insects such as ants, cockroaches, termites, and silverfish come into contact with or ingest borate-treated materials, it disrupts their digestive systems and eventually kills them.
Because the borate is infused throughout the insulation during production—not just sprayed on the surface—it offers long-lasting protection without breaking down over time. This makes CleanFiber a smart choice for attics and wall cavities, especially in homes that have had pest or wildlife issues.
How is CleanFiber Insulation installed?
CleanFiber is installed using a blown-in insulation machine, which evenly distributes the material across attics, wall cavities, or floors. It can be used in both new construction and retrofit projects.
Is CleanFiber Insulation safe?
Yes, CleanFiber Insulation is designed with safety in mind. It's made from 100% recycled cardboard and treated with borate, a naturally occurring mineral that provides fire resistance and helps deter pests and mold—without the use of harmful chemicals.
Unlike some other insulation products, CleanFiber contains no ammonium sulfate, which can release odors or cause corrosion. Its low-dust formula also makes it cleaner and safer to install, with fewer airborne particles that could irritate installers or homeowners.
CleanFiber meets ASTM C739 Class I fire safety standards, and its manufacturing process is tightly controlled to ensure consistent quality and performance.
