Hydronic Radiant Floor Heating Product Details

Why InfloorBoard Works so Well for Radiant Floor Heating

Hydronic radiant floor heating systems being installed.Non-structural InfloorBoard (previously ThermalBoard) is designed specifically for subfloor applications. It is constructed of dense composite board covered with aluminum that spreads floor heat evenly and quickly. InfloorBoard heats the floor rapidly and is easy to control with setback thermostats for maximum energy efficiency. It contains just enough thermal mass to be effective, but not so much that it's difficult to control. No other hydronic floor heating product combines the performance, ease of installation, and cost-effectiveness of InfloorBoard.  Learn about the installation process for InfloorBoard.

InfloorBoard System Components

The InfloorBoard hydronic floor heating system utilizes three different modular boards during installation: straight piece, combo end, and utility end. The specifications for these under-floor boards are as follows:

  Dimensions: Each board is 16"x48"x5/8"
  Square Footage: 5.333 sq. ft. per board
  Weight: Approximately 2.5 pounds per sq. ft. 13.3 pounds per board
  Common Product Mix: Straight, 70%; Combo End, 15%; Utility End, 15%

Thermalboard for hydronic floor heating systems.

InfloorBoard is typically glued and screwed or stapled to a wood subfloor or glued to cement. Then PEX pipe, which carries warm water to heat the floor, is secured into the groove. Heat is transferred from the pipe to the aluminum and the board, providing evenly distributed floor heat. InfloorBoard is manufactured from MDF (medium density fiberboard) or dense OSB (oriented strand board), which are relatively conductive wood products weighing 44-50 lbs. per cubic foot. The board is grooved and then laminated with a top layer of highly conductive aluminum to efficiently disperse and transfer heat away from the groove to the surface area of the whole board, heating your floor safely and evenly.

Putting the Puzzle Together

As with any radiant floor heating system installation, the first step is to obtain a quality design and layout. This can be particularly important for first-time installers, which is why Warmzone offers this service. Warmzone can provide a detailed InfloorBoard layout showing board placement and tubing circuits for your hydronic floor heating system. The layout designs provided are professional CAD drawings of the proper panel combinations to accept the PEX radiant tubing. Contact Warmzone today to talk to one of our radiant heat specialists about this service.
