MR Credit 3: Materials Reuse
1-2 Points
Use salvaged, refurbished or reused materials, the sum of which constitutes at least 5% (one point) or 10% (two points), based on cost, of the total value of materials on the project.
How Mountain Lumber qualifies:
Mountain Lumber reclaimed materials such as antique beams qualify for MR Credit 3.
MR Credit 4: Recycled Content
1-2 Points
Use materials with recycled content such that the sum of postconsumer recycled content plus 1/2 of the preconsumer content constitutes at least 10% (one point) or 20% (two points), based on cost, of the total value of the materials in the project.
The recycled content value of a material assembly is determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value.
How Mountain Lumber qualifies:
Mountain Lumber’s solid reclaimed flooring is 100% postconsumer recycled and 20% of our engineered reclaimed flooring is postconsumer recycled.
MR Credit 5: Regional Materials
1-2 Points
Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% (one point) or 20% (two points), based on cost, of the total materials value. If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) can contribute to the regional value.
How Mountain Lumber qualifies:
This credit varies by project. We often source reclaimed heart pine and reclaimed hardwoods such as oak and chestnut from existing structures within 200 miles of our facility. For LEED projects, we can source regional wood upon request.
MR Credit 7: Certified Wood
1 Point
Use a minimum of 50% (based on cost) of wood-based materials and products that are certified in accordance with the Forest Stewardship Council’s principles and criteria, for wood building components.
How Mountain Lumber qualifies:
100% of our solid FSC® Certified Harvest flooring and 80%-100% of our FSC Custom Engineered flooring carry the FSC Mix certification.
IEQ Credit 4.1: Low-Emitting Materials—Adhesives
1 Point
Adhesives, sealants and sealant primers must comply with South Coast Air Quality Management District (SCAQMD) Rule 1168.
How Mountain Lumber qualifies:
The adhesive used in our engineered products has a low VOC content (5.6 g/L, less water and less exempt compounds) and is in compliance with Rule 1168.
IEQ Credit 4.2: Low-Emitting Materials—Coatings
1 Point
Clear wood finishes, floor coatings, stains, primers, sealers, and shellacs applied to interior elements must not exceed the VOC content limits established in South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings, rules in effect on January 1, 2004.
How Mountain Lumber qualifies:
Mountain Lumber’s pre-finished products contain zero VOCs (less water and less exempt compounds) and are in compliance with Rule 1113.

1 Point
All flooring elements installed in the building interior must meet the testing and product requirements of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda. Mineral-based finish flooring products such as tile, masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated solid wood flooring qualify for credit without any IAQ testing requirements.
How Mountain Lumber qualifies:
Mountain Lumber’s unfinished solid wood products are untreated and qualify for this credit.
