Radiant Heat Subfloors and Underlayment

The addition of in floor radiant heating systems has increased dramatically in recent years. As you may know, not all types of hardwood floors can be used over a subfloor with a radiant heat or hydronic heat systems installed. It is also difficult to find information on which flooring underlayment to use over a radiant heat.

Efloors.com has done its research on this, and has determined that the Mohawk Silent Gard underlayment, has little effect on the heat transference from the radiant heat subfloor to the top of the flooring surface. Because of it's open cell technology, they allow moisture and heat to transfer to the upper flooring layer. As long as the surface temperature of the concrete does not exceed 85 degrees F, you will not compromise the underlayment's effectiveness.

The moisture barrier component of the Mohawk Silent Guard is about 1.5 mm thick, not enough to prevent heat transfer through the vapor barrier. Also, for an underlayment to be effective for this application, it must not have an R value greater than 2.5.

However, Visqueen is normally about 6mm thick and may prevent a portion of the heat from these systems from transferring to the upper flooring layer. Also, any closed cell underlayment may block some heat transfer from radiant heat subfloors.

Lay the underlayment on the floor with the Mohawk Logo facing up. The direction of the underlayment should be parallel to the direction of the laminate floor. For the first row of laminate the underlayment should be placed so that approx 1 inch overlap to all perpendicular walls. Place the following rows next to the 1st on top of the low moisture barrier flap. Remove the adhesive slip and fold back the upper flap onto the second row. Make sure the underlayment fits together tightly. Do not leave gaps. On the last row place the underlayment 1 inch up against the wall. To join rolls on the short side of the underlayment use a moisture resistant tape to connect the two pieces so that water cannot penetrate the underlayment.
