iLevel by Weyerhaeuser is the First to
Receive the NAHB Research Center "Green Approved" Product
Seals of Approval.
The NAHB Research Center "Green Approved" product seal of
approval recognizes structural frame products from iLevel
by Weyerhaeuser with the first certificates under the new
designation. The mark is intended to provide third-party
evidence that building products meet specific scoring
criteria for homes seeking certification to the National
Green Building Standard™ (the Standard), a
consensus-developed standard that was recently approved by
ANSI.
iLevel’s full range of engineered wood products and
solid sawn lumber are now designated as NAHB Research
Center Green Approved products. These include TJI®
joists, TimberStrand® laminated strand lumber (LSL),
Parallam® parallel strand lumber (PSL), Microllam®
laminated veneer lumber (LVL), iLevel Framer Series™
Lumber, iLevel Premium Joists™ and all other wood
structural framing products.
The Green Approved mark indicates third-party documentation
and approval by the NAHB Research Center that a building
product contributes to compliance of specific green
practices for National Green Building Certification to the
Standard. Such products carry a certificate from the
Research Center that identifies the specific sections of
the National Green Building Standard under which the
products can earn points. The Green Approved mark helps
bridge the gap between manufacturers who make green
products and builders and designers who want to use them.
Green Approved products can be found from links on the
Green Scoring Tool at www.nahbgreen.org.
