Construction of Engineered Wood Floor
Engineered wood floor construction commonly consist of 2, 3 or even 5 thin layers. The top layer is a laminated unit with a thickness between ¼ – 9/16 inch. Available as both strip and plank flooring, the width will usually range between 2- ¼ and 7 inches wide. Often found in random lengths of 12 – 60 inches.
- Oak, the most common species used for engineered flooring.
- Any number of species, domestic or exotic can be used as the top or finish layer.
- With engineered wood floor construction the top ply may be a totally different wood species than that of the other plies.
- During construction each of the individual alternating plies will be stacked in the opposite direction.
Construction Benefits
- Through natural forces the plies pull against one another keeping them dimensionally stable.
- This construction becomes far less effected by moisture than a 3/4″ solid wood floor.
- Greater dimensional stability and resistance to moisture allows for use in more areas.
- Engineered wood floors may be installed over concrete slabs and below ground level as long as the concrete slab is dry and clean.
