The Forbo Cinch Loc is okay for use with hydronic radiant heat only. When installing over a concrete subfloor or any subfloor with underfloor heating, always cover the subfloor with a vapor barrier. The edges of the vapor barrier should extend up the walls at least 2� with a minimum overlap of 8". Before installing Marmoleum Click over a subfloor with underfloor heating, you must install a moisture barrier that is at least 0.2 mm thick. Note that this construction will slightly reduce heat radiation. The maximum permissible surface temperature for Marmoleum Click is 85�F (27�C). Keep in mind that loose rugs may function as heat accumulators and so raise the temperature of the Marmoleum Click floor above the maximum surface temperature allowed.
