Is it true the Coretec plus doesn't expand or contract? Confused by this and using 1/4" spacers. And, it does not have to go through an acclimation period? Thnx

The COREtec does not expand or contract under normal conditions. We do still recommend the 1/4" space around your install in the rare instance there is come expansion in the floor. To ensure a proper install we do recommend an acclimation period of 24-48 hours as there may be an extreme environment change between warehousing and your home.
