Wood Fiber Insulation

Wood fiber insulation is an eco-friendly, high-performance solution made from FSC-certified softwood chips leftover from lumber production. These fibers are refined into a loose-bodied material and often blended with borate to make them flame retardant, mold- and mildew-resistant, and insect-repellent. As a carbon-negative and cost-effective insulation option, wood fiber insulation is ideal for residential and commercial buildings alike.
Benefits of Wood Fiber Insulation
Wood fiber insulation provides multiple advantages that make it a top choice for homeowners, builders, and contractors:
- Versatility: Available in blown-in, batt, and board forms, wood fiber insulation can be installed in attics, walls, floors, ceilings, and as continuous exterior insulation.
- Eco-Friendly: Made from renewable, non-toxic wood fibers, wood fiber insulation is safe to handle and contributes to a reduced carbon footprint.
- Minimal Protective Gear Needed: Unlike fiberglass or mineral insulation, wood fiber is gentle on skin and lungs, allowing installers to work safely without gloves or respirators.
- Complementary Fire Protection: Treated with borate, wood fiber insulation can achieve Class A flame spread ratings, providing an added layer of fire protection alongside sprinklers and fire extinguishers.
- Code Compliance: Meets modern International Residential Code (IRC) and International Energy Conservation Code (IECC) requirements, including providing thermal breaks for exterior walls in colder climates.
- All-Season Performance: With a thermal capacity of up to R-4 per inch, wood fiber insulation balances temperature swings and humidity, reducing heating and cooling loads year-round.
Blown-In Wood Fiber Insulation
Blown-in wood fiber insulation is a flexible and carbon-negative solution for attics, wall cavities, and other spaces. The fibers are loosely packed to create a tight, energy-efficient fill, while borate treatment protects against fire, mold, mildew, and pests. Its ease of installation and non-toxic properties make it a safe and effective choice for both new construction and retrofit projects.
Installation Details
Wood fiber insulation is renewable, non-toxic, and safe to handle. Standard construction safety practices should be followed, including protective eyewear and gloves if cutting the material. Proper installation ensures maximum performance and energy efficiency.
Installation Timeline: The time required depends on the size and complexity of the project. Small spaces may take just a few hours, while larger homes or commercial buildings may take several days.

Key Insulation Benefits
Increased Energy Efficiency
Properties with inadequate insulation lose energy through air leaks in attics, walls, windows, and doors. Proper insulation helps seal these gaps, reducing energy waste and easing the workload on your heating and cooling systems.
Better Noise Reduction
Insulation helps limit sound transfer between rooms and floors by absorbing noise within walls, ceilings, and floors. This creates a quieter, more comfortable living environment throughout your home.
Strong Long-Term Value
Although insulation is an upfront investment, many homeowners see long-term savings through lower heating and cooling costs and increased home value. In many cases, insulation upgrades can pay for themselves within five to six years.
