Installation methods vary depending on wood format and site conditions, but here are some general guidelines:
- Solid wood is typically nailed, or nailed and glued, to a plywood subfloor.
- Engineered wood is typically glued down to concrete or plywood subfloors, with or without an underlayment such a sound abating mat or a moisture barrier, depending on site conditions/requirements.
- Engineered floors are also usually the best choice for gluing down over radiant heat installations.
- In either format, when planks are particularly wide, gluing and nailing is always good practice if possible.
