This is the only responsible option for clients who want some kind of solid wood look in areas with potential high humidity conditions, such as a basement. Unlike solid wood, engineered wood can typically be installed over radiant infloor heating. Besides being more physically stable, engineered hardwood flooring is more environmentally responsible because the visible layer of high-end hardwood is relatively thin, extending the amount of flooring that can be made from a given log.
Tongue and groove engineered hardwood is in higher demand than click styles right now, and that’s an advantage for you. Installing tongue and groove using 1/4” staples driven at an angle through the base of the tongue is an excellent way to create a stable floor over slightly uneven subfloors.
Be sure to explain how engineered flooring is not as tough as laminate or vinyl, and it comes in widely varying grades. Explain how the high-end options have a visible top hardwood layer that’s thick enough to be sanded and refinished a couple of times. Cheaper engineered flooring cannot be refinished because the visible wood layer is too thin.
