Coming undone. Do climate extremes really cause delamination?

As engineered wood flooring becomes more prevalent, we are seeing increasing numbers of cases of delamination, especially under the extremes of dry or wet climatic conditions. Here in Germany, oftentimes floor heating is involved, and an increasing number of incidents are also observed after renovations with waterborne coatings. This led us to do some testing of these products in the lab, with somewhat surprising results.
