Engineered or Solid?
Engineered wood is more stable and resistant to changes in humidity and temperature, making it suitable for areas like basements or kitchens where moisture might be an issue. Solid wood, on the other hand, can be sanded and refinished multiple times, providing greater longevity and a more authentic, traditional look. However, it can warp or expand in environments with fluctuating moisture levels. Both options have distinct advantages depending on the installation environment and desired longevity.
Engineered (2-7 Layers)
- More dimensionally stable than solid due to construction of cross plies.
- HDF Core is inexpensive, but only as good as the HDF used.
- Can be installed by nailing/stapling, glue, and some by floating.
- Can be glued directly to proper slab
- Fewer variety of species available
- Usually pre-finished
Solid Wood
- Can be installed on wood subfloors over a proper moisture vapor retarder with a perm rating of less than 1 when tested in accordance with ASTM E-96 Method A. Vapor retarder seams should overlap 4 or more inches.
- Can be installed indirectly over concrete using plywood on slab, sleeper or screed systems, but we recommend engineered wood when installing directly over concrete. These methods can add considerable height to the floor.
- Include strip (tongue and groove), plank, and block (parquet and end grain block).
- Greatest variety of species is available in solid wood
- Pre-finished or unfinished options available for common species
Hardness
The hardness of wood is measured by the Janka Hardness Test (the force required to embed a .444" steel ball to half its diameter in a particular wood ASTM D1037-7.)This scale is a good indicator of how well a species will withstand pressure causing dents and wear. It also is indicative of how hard a wood will be to saw, staple, or nail.
