Solid hardwood flooring is milled from single pieces of lumber, typically cut to three-quarter inch thickness. The lumber is carefully dried in kilns to reduce moisture content to approximately 6 to 9 percent, ensuring stability after installation.
Engineered hardwood is constructed with a real hardwood veneer (top layer) bonded to multiple layers of plywood or high-density fiberboard. This cross-grain construction provides superior dimensional stability, making engineered hardwood less susceptible to expansion and contraction from humidity changes.
The milling process shapes each board with tongue-and-groove edges for precise interlocking during installation. Boards are graded based on their appearance, with select grade offering the most uniform look and character grade showcasing natural knots, mineral streaks, and color variation.
Finishing can occur at the factory (prefinished) or after installation (site-finished). Factory finishes apply multiple coats of UV-cured urethane or aluminum oxide for exceptional durability. Site finishing allows for custom stain colors and a seamless appearance without micro-beveled edges.
