Frequently Asked Questions

How does Stabilized Cellulose insulation compare to traditional Fiberglass insulation?

Stabilized Cellulose is denser, quieter, cleaner, less-toxic, and more efficient than traditional insulation methods.  Check out an In-Depth Comparison of Stabilized Cellulose insulation to other types of insulations

What are the fire-resistance qualities of Stabilized Cellulose insulation?

Non-toxic fire retardants are applied to cellulose fibers during manufacture.  Cellulose has been shown numerous times to perform better in fire resistance testing.  In short, cellulose resists fire damage longer than traditional fiberglass and conforms to all building standards and codes.

Are there any health or safety concerns?

Cellulose is primarily wood-pulp fibers, and a few other subtances that have been well-known to the scientific community for decades.  One such substance is boric acid, which is used as a fire retardant.  Boric acid has a toxicity roughly similar to common table salt.  None of the substances used in the manufacture of cellulose insulation pose health hazards.  Loose-fill cellulose installation can create dust, a potential respiratory irritant.  Not  only do we use a special  low-dust formula, we also apply Stabilized Cellulose, which is cellulose to which a glue has been applied.  All that is required is a simple dust mask during installation.

Is Cellulose resistant to corrosion?

Corrosion problems are not typically associated with insulation, however it can occasionally occur in situations of moisture contact in metal building components.   In such cases, it is important that insulation not aggravate the problem.

Cellulose is tested by certifying laboratories to be corrosive resistant within according to certification standards.

Can Cellulose be installed in tight spaces?

Cellulose is actually preferred for installation in tight spaces because it generally has a higher R-Factor than other fiber insulation.  An example of an optimal location is the perimeter areas of an attic.

Does Cellulose settle over time and lose R-Value?

All loose-fill insulation settles after installation.  S&N Cellulose is always specified and sold at settled density.  This means that settling has already been compensated for in the bag count and material weight columns of coverage charts.  This may, or may not, be the case for other loose-fill insulation.

Neither Stabilized Cellulose or R-Foam insulation will break-down or decay with age, and should last the life of the structure, under normal conditions.

Is R-Foam toxic?

R-Foam is non-toxic and biodegradable.

R-Foam is made up of three components:  foam, catalyst, and resin.  The foam itself contains no hazardous substances, and less than 0.25% formaldehyde.

The catalyst contain less than 10% phosphoric acid and only comes into play at the time of installation.

Are there tax incentives available?

Yes.  Our products qualify for federal, state, and local utility tax, rebate and other incentives, because they are “green” products.   However, you will want to use current tax incentive resources to evaluate your options at the appropriate time, as they will change from time-to-time.
