Why wood warps

There are many reasons why a board can be downgraded. Physiological characteristics are, for the most part, beyond our control and most mills have measures in place to minimize losses from machining problems. The other significant reason for lumber downgrade is the presence of warp.

This presentation will deal with all of the factors contributing to the development of warp and what can be done to minimize the losses.

Brief synopsis

Studies conducted at industrial drying sites have shown that up to 15 per cent of the boards placed in a kiln develop warp that is severe enough to cause those pieces to be downgraded by one or more grade levels.

There are many reasons why a board warps with some of these reasons be controllable factors whereas others being beyond our direct control. Even some of the non-controllable factors can be managed to minimize their impact on the final product.

This presentation will deal with identifying all of the root causes for warp and what can be done to minimize or eliminate their impact on mill profitability. A big part of this process is quantifying the actual losses and determining the economic impact. From there, the viability of implementing the various control measures can be assessed.

An objective for every drying operation should be to fully understand their drying losses, recognize the available control measures, and know that they are not leaving any easily recovered money on the table. This webinar on degrade losses due to warp will help you achieve that objective.

There will be approximately 15 minutes at the end for questions.

And all of this for only $25!
