Did you end up choosing this floor? I am also considering it and wondering how your experience was

A high quality engineered floor will have the same or longer wear life as a solid wood floor. This isn't usually a big deal in residential as you are talking at least 45 years of life... Engineered wood flooring can cope with changes in moisture better than a solid wood floor, but if you have a good HVAC system and monitor the humidity in your home, both will be fine. Solid wood floors are not recommended below grade, for example in the basement. Our standard 5/8" thick engineered floor will give you 3-4 sand and refinishes. This floor can be glued to the slab and will line up with carpet and most tiles. This means you don't have to drop the slab (money saver!) or use transition pieces. Some areas where it is very dry have had issues with the thicker engineered floors (3/4" with 6mm wear layer) as the plywood base dries out at a different rate to the wear layer. One of our clients (Flooring installer) in Arizona is replacing engineered with solid as it handles that climate better. Since it sounds like you are doing a remodel, you are probably best to go with an engineered floor. A 5/8" thick engineered wood floor from our company has a 4mm wear layer and will give you 3-4 sand and refinishes. This you can glue to the slab and will take up around the same amount of thickness as the travertine did. This means you will not have to replace the trim, cut off the bottoms of doors etc. Typically a solid wood floor is installed on a plywood sub-floor. On a new build the slab would be dropped on those areas to allow for the extra thickness. A quality engineered wood floor is not inferior to a solid wood floor in anyway. Once it is installed you will not be able to tell the difference. If you have further questions, feel free to reach out!

The in-floor radiant heat is going to be the BIGGEST issue. I would look at a high-end laminate that is relatively thin (8mm or so). The thinner the material the BETTER the heat will move THROUGH the product and into the air. Carpet does well with in-floor radiant heat because it airy (lots of holes in the weave of the carpet to allow heat to pass through). Most vinyl products do NOT like radiant heat. Many engineered wood floors do not like radiant heat (it is a very 'dry' form of heat = very hard to keep wood moist and happy). A beautifully manufactured laminate will give you all the wear and tear necessary and will be LOW VOC (or no-voc if you work with Swiss manufacturing = www.lico.ch). I've seen the chemical report for Lico floors...it is MIND BLOWING how low the VOC content is. It is better than E0 (the highest known rating for flooring Europe has = 20 years ahead of CARB II). Anyway...your infloor radiant heat is a cursed blessing. The curse is your limitations for your flooring (carpet is awesome; laminate is fine; vinyl is super picky and engineered hardwood is sometimes allowed with plenty of caveats that are hard to maintain).
