Great Northern Insulation uses Climatizer Plus cellulose blowing insulation consisting of shredded newsprint that has been treated with an anti-fungal, fire retardant product. Made of 100% recycled and processed paper, the resultant product is returned to individual cellulose wood fibers which provide R-3.85/inch of thickness.

At Great Northern Insulation we use fiberglass blowing insulation which provides R-3/per inch of thickness. This fiberglass is identical to that used to manufacture pre-formed batts you can buy at your building supply store except it is chopped & ground up to allow blowing to depths up to R-60.

Owens Corning PROPINK Wall Insulation System
Great Northern Insulation is always looking for the best products and insulation solutions to offer our customers. From the most trusted name in fiberglass insulations comes the premium fiberglass wall insulation system. It is an alternative to roll or batt insulation in walls, ceilings or other enclosed cavity applications, for both new and retrofit projects. It eliminates gaps and pockets which may result with other approaches providing a "seamless" blanket of insulation.
