All loose-fill insulation products can and will settle over time. However, the installed thickness takes the effect of settling into account. When installed properly, cellulose insulation will not settle below the intended R-Value.
Yes, cellulose insulation is a perfect solution for upgrading energy efficiency. It may be installed directly on top of existing insulation in attics or added to walls without the need for a costly renovation of the interior wall finish. It is simply blown into the wall cavities through small holes, which are easily plugged or patched.
Cellulose insulation forms a seamless blanket of thermal protection. Because of its loose-fill nature, it completely fills all cavities and voids, whereas fiberglass batts may not properly fit and must be compressed around plumbing and wiring, thus reducing R-Value. Furthermore, cellulose insulation is much denser than both fiberglass batts and fiberglass loose-fill insulation, resulting in a dramatic reduction in air infiltration.
Foam insulation is most commonly applied in wall cavities, and is often applied at a thickness that does not completely fill the cavity. Insulation is most effective when it is in contact with all six sides of a wall cavity. Open-cell foam insulation and cellulose insulation share similar traits in their ability to reduce air infiltration. The R-Value of open-cell foam insulation is slightly lower than cellulose. While cellulose insulation is treated for flame resistance, polyurethane foam is extremely flammable.
R-Value is a measure of resistance to heat flow through a given thickness of material. The higher the R-Value, the greater the resistance will be. Resisting heat flow is the primary purpose of insulating, which in turn lowers energy costs.
Air infiltration is the movement of air into your home through voids, seams, cracks, and other structural irregularities. R-Value does not measure the effects of air infiltration. The movement of air through insulation will greatly impact its performance. High-density cellulose insulation is extremely effective at minimizing air infiltration.
That’s easy – cellulose.
Our cellulose insulation is made from 82% recycled paper, primarily newsprint, giving it the highest recycled content of any insulation product. Cellulose insulation also has the lowest embodied energy score of any major insulation. It takes less energy to produce and transport cellulose insulation, which means fewer emissions are released in manufacturing it. Fiberglass uses approximately 10 times more energy than cellulose insulation to produce and transport, while foam products, derived from petroleum, use even more. In addition, neither of these products is recyclable.
No. By law, all cellulose insulation products must be treated for flame resistance. The fact is cellulose insulation has been shown to effectively slow the spread of fire unlike fiberglass and foam which are not treated for fire resistance. Fiberlite Technologies even offers a special two-hour rated firewall insulation product.
Moisture is typically added when spraying cellulose in newly constructed walls. The water is added in a very low concentration to increase binding properties. In most cases, depending on the humidity level, the drywall can be installed 24-48 hours after insulating with cellulose. Our cellulose Insulation is specially treated with Board Defense to enhance its mold and mildew resistance.
Cellulose is typically comparable to loose-fill fiberglass and fiberglass batts. Cellulose insulation is much less expensive than foam while offering many of the same superior air sealing characteristics.
Our product is the most environmentally friendly application available. It’s non-irritant properties versus fiberglass are a huge advantage. It’s both fire retardant and mold resistant. And it’s competitively priced (or in some cases cheaper) than other forms of insulation.
