Loose-fill insulation is blown into attics, nonconforming spaces and hard-to-reach areas, like corners, edges and around framing.  When it's applied to the recommended thickness and specifications, you can be assured that your home is energy-efficient, with minimal heat loss.


It is typically installed in open attics of both new and existing structures.  It can also be used in retrofit closed-cavity applications such as exterior sidewalls or floored attics.


Clean, Safe & Lightweight


Cellulose insulation is naturally flammable and must be treated with chemicals to make it fire retardant.  Even properly treated, cellulose can smolder when exposed to heat as low as 450°.  Blown-in insulation offered by Whitson Insulatin Company is noncombustible and cannot contribute to the spread of fire.


Unlike cellulose, this insulation will not rot, mildew or deteriorate.  It will not hold moisture and will not suffer permanent loss of R-Value.  It does not accelerate corrosion of pipes, wiring or metal studs.  Virtually all scientists agree that fiber glass insulation is safe to manufacture, install and use when simple, recommended work practices are followed.  This type of non-cellulose insulation leaves minimal dust.


Weight limitation recommendations show that there is a potential for ceiling drywall sag with cellulose at R-Values above R-30 when the cellulose is installed over traditional 1/2" ceiling drywall, 24" on center.  Blown-in insulation offered by Whitson Insulation Company can be installed up to R-70 over 1/2" ceiling drywall without exceeding ceiling weight limits.
