Delamination – Engineered Wood
Delamination (Engineered Hardwood Flooring)
Floor Detective® Claims and Conditions Guide
Summary
Delamination is the separation of bonded layers within an engineered hardwood flooring plank along an internal adhesive interface. Engineered hardwood flooring relies on adhesive bond lines to unify multiple wood layers into a composite structural panel capable of responding as a single integrated unit during environmental change and normal service exposure. When bond-line separation occurs, the affected plank may no longer function as a fully unified composite structure. Delamination is identified by separation along adhesive interfaces rather than rupture directly through wood fibers. Manifestation may include surface irregularity, movement, end lift, veneer separation, hollow response, or localized distortion depending on the location and extent of layer separation. In some conditions, fracture morphology may contain both adhesive-interface release and cohesive wood-fiber rupture as internal stress redistributes through the layered system. Proper classification requires evaluation of fracture morphology, layer involvement, environmental exposure, and overall flooring behavior rather than appearance alone.
