About Blown-In Wood Fiber Insulation

Blown-in wood fiber insulation is an affordable, carbon-negative solution for homes and commercial buildings. It is used in places such as attics and stud cavities.

What Is Blown-in Wood Fiber Insulation?

Wood blown-in insulation is made of softwood chips that are transformed into a loose-bodied fiber. It is then blended with borate, making it flame retardant, and an inhibitor to mold and mildew growth. Blown-in wood fiber insulation comes in poly bags weighing approximately 25 lbs and can be stacked on pallets for shipping for larger projects.

Blown-In Wood Fiber Insulation Benefits

Blown-in wood fiber insulation is a solution that fulfills construction and sustainability needs. It provides insulation solutions for residential and commercial buildings in attics, ceilings, and more.

Stable R-Value

R-values are assigned to insulation products prior to installation and it is important that they retain those values to provide the functionality of insulation. Blown-in wood fiber insulation has stable R-values with interlocking loose fill insulation fibers which reduce air pockets, risk of settling, and a changed R-value.

Fire Protection

Blown-in wood fiber insulation is often blended with borate during the manufacturing process. The addition of this compound allows the product to achieve an ASTM E84 Class A flame spread and smoke development index. Both blown-in wood fiber insulation and borate are non-toxic materials, making the end product a safe and environmentally-friendly solution.

Energy Saving by Nature

Blown-in wood fiber insulation can save energy during installation and after installation. Fill insulation products have more insulating power per pound, saving valuable energy when using insulation-blowing machines. After installation, blown-in wood fiber insulation cuts energy costs with its low thermal conductivity and high heat transfer capacity for different climates.

Moisture Managing

Wood fiber can absorb and store (and later release) moisture, resulting in increased interior comfort. Moisture passes through, reducing the risk of mold, rot, and allergens. Timber products also effectively redistribute unwanted condensation or moisture build-up evenly.

Sound Protection

Stand-alone and assembly solution for reducing airborne and impact noise.
