| KD or KD-HT? What's The Difference? | 2007-10-30 |
When choosing whether to stamp your product HT or KD-HT it’s important to remember the difference between the two stamps .
Heat treated lumber may be marked as KD-HT or HT. If marked KD-HT, the lumber is being guaranteed as 19% or less moisture content and that it has been heat treated to at least 56 degrees C (minimum of 133 degrees F) for at least 30 minutes at the lumber core. A mark of HT signifies that the lumber has been heat treated to at least 56 degrees C for at least 30 minutes at the lumber core, without moisture content designation.
