This step of the radiant heat panel install goes after the preparation and installation of the panels. We recommend to review the complete install guide and our supplied plan set before work begins.

Linoleum Flooring Deployment Instructions

Always install a substrate underlayment between the Warmboard and the finish linoleum.


Install method

We recommend the Stencil Method to avoid tubing damage.

Suggested Underlayments

  • 1/4″ or 1/2″ interior plywood or OSB
  • 1/4″ or 1/2″ tile backerboard (bathrooms, kitchens)

We encourage a 3/4″ thick finish floor assembly, but priority should be given to ensure matching floor heights throughout the house.

Install recommendations

When using a plywood or OSB (or equivalent) underlayment, you MUST fully acclimate the panels before installation. If the moisture content of the underlayment is too high, it will shrink from the floor heating and cause an installation failure.

  • DO NOT use adhesive with plywood or OSB, just staples or screws.
  • Surface temperatures of the finish flooring should not exceed 85˚F.
  • Failure to follow these guidelines will void any product warranty.
  • Follow all installation instructions provided by your finish flooring manufacturer.
