Kember Lam™ is designed for use with below, on, or above grade installations. With concrete subfloors, the moisture level must be below 5lbs/1000ft2 in 24 hours (floating) or below 3lbs/1000ft2 in 24 hours (glue down) and wood subfloor needs to be below 12%. If the subfloor being covered is radiant-heated, Kember Kreative Floors™ recommends using KemberLam™ flooring. KemberLam™ is specially designed for use on radiant-heated subfloors.
