Seminars

Nu-Wool has developed Educational Outreach Programs based on our technical and instructional experience. Following our educational criteria, Nu-Wool’s team of area managers and technical staff can meet with you, your company or organization to provide in-depth understanding of cellulose insulation and the unmatched benefits of Nu-Wool Premium Cellulose Insulation.

AIA Continuing Education

Architects must earn 18 Continuing Education learning unit hours in each calendar year – 12 of which must be Health, Safety Welfare units (HSW) – in order to remain an AIA member in good standing. Nu-Wool’s AIA Continuing Education Programs (1 HSW learning unit each) address the key issues that builders are facing today, and provides architects with valuable industry insight into current insulation performance ratings and research findings, such as acoustical properties and fire test results for all types of insulation.

Nu-Wool frequently presents its AIA Continuing Education Programs to architectural firms throughout its market area. Contact the Nu-Wool Technical Services Department for more information.

Popular FAQ's

Section R 302.10 of the 2012 IRC requires cellulose insulation to pass the following tests:
  • ASTM E-84
  • Consumer Protection Safety Commission 16 CFR parts 1209 and 1404
  • Additionally all thermal insulation must follow the Federal Trade Commission rule 16 CRF part 460
As noted on our bags and in our literature, Nu-Wool Premium Cellulose Insulation is an Underwriters Laboratories Classified Product. Nu-Wool uses UL as an independent certified third party to conduct all of the required tests. A copy of compliance is available from Nu-Wool and from UL on their web site under “certifications.”  In addition,  UL Evalulation Report – UL ER8078001 confirms Nu-Wool Premium Cellulose Insulation meets building code requirements.
See UL classification documents R-8078 & R-8078-B, and UL Evaluation Report – UL ER80780-01

ASTM is responsible for writing the test standards. ASTM C-739 provides most of the test procedures while ASTM E-84 and E-970 provide the standard to determine flame spread and smoke developed as well as critical radiant flux, respectively.

ASTM C-739 outlines test procedures for the following physical properties of cellulose insulation:
  • Design Density
  • Critical Radiant Flux
  • Fungi Resistance
  • Odor Emission
  • Smoldering Combustion
  • Thermal Resistance
  • Moisture Vapor Sorption Corrosion
See UL classification documents R-8078 & R-8078-B

Yes, in fact there are over 50 fire wall assemblies using Nu-Wool Premium Cellulose Insulation listed on the UL website.

The 2012 International Residential Code defines 3 classes of vapor retarders:

  • Class I0.1 perm or less (i.e. sheet polyethelen, unperforated aluminum foil)
  • Class II1.0 perm or less and greater than 0.1 perm (i.e. kraft-faced fiberglass batts)
  • Class III10 perm or less and greater than 1.0 perm (i.e. latex or enamel paint)

Buildings in zones 1-3 do not require any class of vapor retarder on the interior surface of insulated assemblies. Zones 4-8 require nothing more than a Class III vapor retarder on the interior surface of many types of insulated assemblies, dependent upon the specific zone and wall construction components (ordinary latex paint qualifies as a class lll vapor retarder).   Consult the building codes that affect your area.

No.  Building codes, as well as most flue and chimney manufactures, require a minimum air space between flues and any combustible material.
