All that warping and twisting of Engineered Hardwood Flooring-No Thanks
Some Engineered Hardwood Floor Manufacturers are recommending and require their
Engineered wood floors be installed with minimum relative humidity of 35% to
40%. This a relative humidity higher than the minimum required by NWFA of
Maintaining a minimum relative humidity in the Northeast of 35% to 40%
is basically difficult to impossible. Some Engineered wood floors cannot manage the lower relative humidity and moisture cycles and as a result may warp, twist and/or delaminate.
Some top reasons for these Engineered wood floors not able to endure the moisture cycles of low relative humidity is that the wood flooring is manufactured with inconsistent thickness in plies and that different species used in the plies of the engineered wood flooring.
