UNDERWOOD floor coverings are produced within 20-30 days depending on the decor and production volume. Before production starts, a sample is made for approval.
Floor coverings made of natural wood UNDERWOOD is a combination of beauty, style and quality.
UNDERWOOD solid board is made from oak, and oak is the most durable and durable type of wood.
TheEngineering Board or American Two-Ply has a valuable 4mm oak ply on high-strength plywood, making it an incredibly stable construction.
