Hardwood Flooring Engineered for Perfection PurezaWood Uses the Latest Technology to Prevent Movement of Hardwood Flooring & Broaden Installation Options News provided by Share this article Share this article CHICAGO, Feb. 1, 2021 /PRNewswire/ -- One of solid hardwood flooring's largest problems is the shifting that occurs when temperature and humidity levels change, causing wood to expand and contract. This can cause problems such as cupping (the edges of the wood rise) or gapping (spaces between boards). Potentially, this could damage flooring beyond repair. PurezaWood's engineered hardwood flooring has the solution. They use Flex-Oriented Technology to keep floorboards in place and prevent movement. While other hardwood floors expand and contract along with the weather, PurezaWood flooring resists; it can withstand greater temperature and humidity variations.
