Proper storage and handling practices of lumber

January 13th 2013 in Wood Products - #lumber

You don’t have time to fuss with mold on a job pack or a builder you are supplying. Let’s keep this important topic on the radar – read our tips below and download our Technical Bulletin. Working together, we can eliminate this nuisance throughout the supply chain – from mill to consumer.

How does mold grow?

The key factors for mold growth are oxygen, temperatures exceeding 40° F, and moisture content above 19%. Since little can be done to impact oxygen or temperature levels, protecting wood from
moisture is critical to preventing mold growth.

What you can do:

  • Keep bundles in a well-drained area.
  • Protect bundles from direct moisture exposure by placing them under wrap, tarp or other vapor-permeable material, preferably under a covered structure.
  • Inspect wrap or covering regularly for holes and gaps.
  • During transit to the jobsite, ensure products stay wrapped or covered.
  • Do not store wood products in direct contact with the ground.
  • On the jobsite, do not open bundles until time of installation and re-wrap unused partial bundles.
