EQ Credit 4.1 - Low-Emitting Materials, Adhesives and Sealants
General Description
Reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
Guardian 275® and Auburn®
Please note: LEED® EQ Credit 4.1 states that the adhesives and sealants which specifically apply to the credit are defined as “inside of the weatherproofing system and applied on-site.” Because of this definition, possible credit is dependent upon the installer. Major Industries’ installation manuals specify Tremco, G.E. and Dow-Corning sealants as “Approved Installation Materials,” and these companies’ standard sealants contain anywhere between 0-40g/L when applied and most reach 0g/L when fully cured – all well below the 100g/L VOC limit specified in LEED EQ Credit 4.1. (Please contact the installer for specific information on the types of sealants used on-site and refer to each product’s data sheet for VOC data.)
For those interested in factory-applied adhesives (which do not count toward the credit but are significant to the health of building occupants), Major's Guardian 275® panels feature a high strength, factory-applied proprietary bonding adhesive that has been found to have 0g/L per South Coast Air Quality Management District (SCAQMD) test methods. Materials used in the manufacturing of our Auburn® skylights are also well below the VOC limits outlined in the credit.
EQ Credit 4.2 - Low-Emitting Materials, Paints
General Description
Reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
Guardian 275® and Auburn®
Please note: LEED EQ Credit 4.2 states that the liquid paint finishes (interior) which apply for the credit are defined as “inside of the weatherproofing system and applied on-site.” When the option is available, specify factory-applied rather than field-applied paints. In addition, factory-applied paints that contain VOC's (e.g. baked enamels such as Duracron or Acrabond) can be applied using specialized equipment that captures and destroys VOC's in the painting process, with 95%+ efficiency. Major Industries works with finishing partners that utilize such equipment and documentation can be provided to the design professional evidencing use of such equipment when painting a project.
- Powder Paint Finishes (Interior). This option provides a VOC-free coating.
- Anodize Finishes (Interior). This option provides a VOC-free coating.
It may be possible to obtain EQ credit 4.1 and 4.2 by incorporating Major Industries' daylighting systems into the building's natural daylighting requirements.
