1.4 DEFINITIONS
A. Thermal Conductivity (K value): Units of Btu-inch/hour per square foot per degree F.
B. UL GREENGUARD: Provides independent third party, Indoor Air Quality (IAQ) certification of products for emissions of respirable particles and Volatile Organic Compounds (VOC's), including formaldehyde and other specific product related pollutants. Certification is based upon criteria used by EPA, OSHA, and WHO.
C. EPA: Environmental Protection Agency.
D. WHO: World Health Organization.
E. ASJ+: All Service Jacket composed of aluminum foil reinforced with glass scrim bonded to a kraft paper interleaving with outer film layer leaving no paper exposed.
F. ASJ: All Service Jacket (no outer film).
G. SSL+: Self-Sealing Lap with Advanced Closure System.
H. SSL: Self-Sealing Lap.
I. FSK: Foil Scrim Kraft; jacketing.
J. PSK: Poly Scrim Kraft; jacketing.
K. PVC: Polyvinyl Chloride.
L. Glass Mineral Wool: Interchangeable with fiber glass, but replacing the term in the attempt to disassociate and differentiate Glass Mineral Wool from the potential health and safety risk of special purpose or reinforcement products that do not meet the bio solubility criteria of insulation made from glass. Rock Mineral Wool will replace the traditional Mineral Wool label. Both are used in lieu of the Mineral Fiber label.
M. ECOSE® Technology: a revolutionary binder chemistry that enhances the sustainability of products. The "binder" is the bond that holds the Glass Mineral Wool product together and gives the product its shape and brown color. ECOSE Technology is a plant based sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in Glass Mineral Wool products. Products using ECOSE Technology are formaldehyde free and have greater reduced global warming potential than compared to products of the past.
N. UL GREENGUARD Gold Certification: (formerly known as GREENGUARD Children & Schools Certification) offers stricter certification criteria, considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and healthcare facilities. It is referenced; by both The Collaborative for High Performance Schools (CHPS) and the Leadership in Energy Environmental Design (LEED) Building Rating Systems.
O. UL Environment Formaldehyde Free Verification Requirements: For a product to be verified as formaldehyde free, product samples must have a measured emission factor of less than or equal to 5 µg/m²h at 24 elapsed hours or 3 µg/m²h at 336 elapsed hours. An emission factor of
5 µg/m²h corresponds to measured chamber concentration of 2.5 µg/m³ for a typical building ratio of 0.5 m²/m³. This chamber concentration is comparable to, or below typical outdoor air concentrations. This demonstrates that the formaldehyde exposure from products labeled as formaldehyde free will not contribute to airborne formaldehyde concentrations at greater levels than those found in the natural outdoor environment.
P. Declare and The Living Building Challenge – The Living Building Challenge is a philosophy, advocacy tool and certification program that addresses development at all scales. The purpose of The Living Building Challenge is to define the most advanced measure of sustainability in the built environment today and acts to diminish the gap between current limits and ideal solutions. Declare supports The Living Building Challenge by providing a transparent materials database that project teams can select from to meet Imperative 11.
Q. Imperative 11, Red List – requires that manufacturers disclose the ingredients in their products to insure that they are free of Red List chemicals and materials. The Red List represents the “worst in class” materials, chemicals and elements known to pose serious risks to human health and the greater ecosystem.
R. Underwriter’s Laboratories Environment (UL Environment): offers independent green claims validation, product assessment and certification. UL GREENGUARD provides third party credibility for sustainable products.
S. UL Environment Claims Validation (ECV): service and label tests a manufacturer’s product and validates that the environmental claims they make in their marketing and packaging materials are factual. This Environmental Claims Validation (ECV) service will allow manufacturers to verify that their products contain a quantifiable amount of recycled content and, as such, help limit raw material extraction and reduce landfill waste. It also will enable products to qualify for LEED® points under Pilot Credit 43: MR – Certified Products.
T. EUCEB: exonerated fiber from a health and safety standpoint by the European Certification Board process.
U. Recycled Content: materials such as bottled glass collected at curbside or other collection sites after consumer use and/or materials used or created from one manufacturing process which are collected as scrap and placed back into another manufacturing process rather than being placed in a landfill or incinerated.
V. Polybrominated diphenyl ethers (PBDE) such as Penta-BDE, Octa-BDE or Deca-BDE fire retardants: have been linked to adverse health effects after exposure in low concentrations.
W. UL Classified: UL has tested and evaluated samples of the product with respect to certain properties of the product. UL Classifies products to:
1. Applicable UL requirements.
2. Standards for safety.
3. Standards of other National and International organizations.
X. EPD: Environmental Product Declaration. A third party verified document that reports environmental data of products based on the Life Cycle Assessment (LCA) and other relevant information, and in accordance with the International Standard ISO 14025 (Type III Environmental Declarations).
