STRAIGHT TALK ABOUT
FRAMER SERIES

LUMBER
Weyerhaeuser’s Framer Series
™
lumber is mechanically graded to virtually eliminate
warping, and each board comes with the crown clearly marked to speed up
installation. With lumber like this, framing goes up fast, crews won’t spend valuable
time culling, and there’s less material waste when the job is done.
Each piece of Framer Series
™
lumber is performance tested to meet specic strength
and density requirements. Because it's more stable than commodity boards,
Framer Series
™
lumber is ideal for any application—even those where vertical-use-only
products aren’t allowed. That gives crews more exibility at the job site and helps
reduce the potential for red tags.
Only Framer Series
™
Lumber offers so many benets:
• Limited warranty against warping
• Floors, walls, and ceilings stay at and even
• Fewer callbacks to repair drywall cracks
• Crown edge clearly marked on each board
• Full lateral shear wall capacities—no species reduction needed
• Meets or exceeds all building code requirements for framing lumber
• Mold inhibitor helps material stay clean and bright, reducing product loss
and callbacks
