Some Advantages & Disadvantages to Engineered Flooring.
Pros
Lower Cost
Compared to solid wood flooring, everything related to engineered wood flooring costs less, from materials to labor. Note this is only true for the same wood species; for example, an engineered oak floor may be less expensive than a solid oak floor, but an engineered teak floor may be cheaper than a solid oak floor.
Temperature and Moisture Resistant
Due to its composite core layers, engineered wood flooring is not as sensitive to changes in temperature or to moisture as solid wood flooring. Though there still may be some warping—typically if moisture issues are left unaddressed (as in the case of a standing pool of water)—the overall amount of swelling and shrinking is far less than that seen in a solid wood floor.
Environmentally Conscious
If you’re concerned about the environment, engineered wood floors may be the way to go. These floors use less hardwood per plank than solid wood floors, which may be a deciding factor if you are interested in exotic or rare species of wood. Combined with a reduced need for toxic glue (to adhere layers together) and little to no sawdust; these floors are eco-friendly and sustainable. That being said, this does vary from company to company, so make sure to look at the environmental certifications of the manufacturer you buy from.
Cons
Limited Resurfacing
Because of the veneer layer, an engineered hardwood floor can only be sanded and refinished a few times—and sometimes only once—before the hardwood erodes to reveal the core layers. How many times you can resurface is dependent on the thickness of the veneer layer.
High Level of Maintenance
Since the surface layer of an engineered wood floor is made of hardwood, you will need to actively maintain your floor in order to retain its quality—exactly like you would for a solid wood floor. Fading, scratches and dents are all common issues with wood floors but can be reduced and prevented by taking proper protective precautions.
Low Quality
In an effort to cut down on time and money, some manufacturers may use cheap materials in their flooring, leading to floors with poor structural integrity. Make sure to research carefully before choosing a manufacturer.
