Blended cellulose insulation is a widely used insulation product made up of a blend of borates and ammonium sulfate, making it a highly rated fire blocking insulation product that helps resist the spread of flames.

Blended Cellulose Insulation Benefits

Blended cellulose insulation is an insulation product with a flexible R-value and great fire rating that is known for its ability to seal cracks and small spaces.

Flexible R-Value

One of the top benefits of blended cellulose insulation is that since it is applied in a loose, blown-in form, it has a flexible R-value to fit whatever needs of the climate area you’re in. Simply add more material to the area to increase the R-value and performance of the product.

Great Fire Safety Rating

Blended cellulose insulation is an insulation product that is known for its flame retardant capabilities, due to its mixture of borates and ammonium sulfate. This gives it a high fire rating that contractors are looking to utilize in both residential and commercial construction in climates all over the U.S.

Top Choice for Sealing Cracks and Small Spaces

Unlike many other insulation products, blended cellulose insulation is able to fill in tight spaces and cracks in any area of a home or building of any type, due to its ability to be applied loosely. This helps provide excellent air filtration capabilities, which keeps energy costs low and increases efficiency.
