For this application, we recommend installing wood sleepers and using a combination of nailing and gluing to install the flooring. Highly recommended to protect your floor: 82°F (27°C) maximum floor temperature and a minimum humidity level of 40% in colder months or manufacturer recommended temperature and humidity levels.
Quarter-sawn wood flooring is recommended as it's always more stable under conditions of extreme moisture or heat, and is always a good choice over radiant heat. Plain-sawn wood will move more than quarter-sawn.
Allow proper adhesive & self-leveling cement cure times as recommended by the manufacturer before powering-up the WarmlyYours electric radiant heat system.
