cut" shows typical wood movement from the "green" stage to the
Kiln Dried "red" stage. As the cut clearly shows, pieces #1,2 and 3
shrink and move unbalanced and consequently move at indifferent rates through
out the pieces of wood. There is an argument that once the wood is kiln dried
that the movement is over.
Tapertite's position is that all wood, no matter how carefully dried and conditioned in a
Kiln has memory. When wood takes on moisture during the summer months, the wood
cells "grow" comparable to how they shrink during the drying process
and the piece of wood
wants to revert towards its original state. This is what we call "wood
conclude that a narrower piece of wood is better for the radiant heat
application because there is less grain variation and we somewhat agree with
this thinking. Please bear in mind that the cut shows a fairly large log,
however in today's tree harvest, more juvenile trees are taken so the grain,
even in the more narrow flooring strip, (see pieces #3 and #2) has more movement
because of typical, smaller log diameters.
Piece #5 shows that with a quarter or rift sawn cut the movement is balanced and
this will allow a consumer the flexibility of a wider board floor without
compromising the integrity of the floor due to radiant heat or lake
that piece #4 should never be used in a plank floor under any circumstance as
you can see the movement of this cut is unacceptable.
