Rigid-core planks consist of a top wear layer, a decorative film, a solid structural core (SPC or WPC), and an attached backing. This rigid construction allows for a locking system that is structurally sound and less prone to gapping. Traditional flexible LVP is designed as a soft, pliable, and thinner product that often requires a full-spread adhesive installation. While flexible LVP offers a more authentic tactile feel, it is less forgiving regarding subfloor irregularities and requires more intensive preparation than rigid-core options.

What are the structural differences between rigid-core planks and traditional flexible LVP?
Rigid-core planks feature a dense, solid inner core that provides stability and hides subfloor imperfections. Traditional flexible LVP is thinner, composed entirely of vinyl layers, and requires a perfectly smooth subfloor, as the flexible material will telegraph imperfections upward.
