Wood is the way to go when heating your home or business!

The Crete-Heat™ Insulated Floor Panel System, is an easily assembled modular board insulation, vapor barrier and radiant tube holding grid that allows for simplified installation of hydronic radiant floor heating systems in basements, garages, main floor slab on grade and above grade installations where concrete or gypcrete is normally used.

The Crete-Heat™ Insulated Floor Panel System is 2 7/8" overall in thickness, with 2" of solid EPS foam providing an R-10. Independently tested by Intertek Semco in Canada. Our retrofit or above grade panel provides 2 1/8" overall in thickness, with 1" of solid EPS foam providing an R-6 with a 23db sound reduction knob on the lower surface. Each interlocking panel covers up to 8 square feet with fasteners for 3/8", 1/2" and 5/8" radiant tubing and our Ice Melt panel holds 3/4" - 1" PEX Tubing. A 10-mil polystyrene film provides the vapor barrier.


Saves Labor NOW and Energy FOREVER.

  • Cuts radiant heat install time by as much as 2/3
  • Designed to hold PEX tube securely in place with wider & deeper fastener
  • 3 thicknesses available for both new construction and retrofitting existing buildings
  • UV protected packaging for outdoor storage
  • 2 different knob designs for holding 3/8" to 1" PEX tubing
  • Special sound deadening knobs for upper floor applications

What Makes Crete-Heat™ Green?

  • Since the 1950s, EPS has always been CFC- and HCFC-Free.
  • EPS provides stable R-value and does not need to be adjusted for age.
  • Recycled content can be specified for certain building applications.
  • EPS mold resistance tests favorably in accordance with ASTM C1338.
  • EPS does not adversely affect indoor air quality.

Why Choose Crete-Heat?

  • Easy to move around site and store
  • Panels have been placed in UV protected bags to protect the panels during storage outdoors
  • Traditional 4' x 8' sheets are cumbersome to handle and create trip hazards where sheets meet because they don't lay flat or interlock
  • When using traditional 4' x 8' sheets the tube sits on top of the sheet creating trip hazards and are susceptible to damage from foot or equipment traffic
  • Tremendous labor savings. One-person PEX installation frees up others for other jobs
  • PEX tube spacing is exactly on 3" increment centers. No more "close enough"
  • No taping required
  • Minimal Waste
  • No more balky staplers to fail you

Here's how it's done!

Determine the Layout

Rectangular structures offer no real challenges in determining which direction you will work in laying the panels. If one of the dimensions is evenly divisible two or four, work along that dimension. Structures with irregular exterior wall will require you to think a little about how best to proceed.  Assuming the top of the drawing is north, keeping cuts to a minimum should be your primary concern. The west to east dimension is 11 feet. The north-south dimension is 13 feet. In general, starting at the upper left-hand corner of the room is preferred as the panels work best left to right as you would read words on a page. In the above illustration the numbers reflect the panel used with the proper layout to minimize waste.


Fill material should be leveled as close to +/- 1/4" as is reasonable. One of the benefits of using the panel is that the 2' x 4' panels will float independently of the surrounding panels thereby eliminating broken foam boards and trip hazards. You can also level as you go if you feel comfortable with the beginning grade of your fill material.

Getting Started

Using a box cutter or key hole saw, cut the tongue portion of the interlock off of the 4' dimension going along the north wall as well as the tongue portion that will butt up against the west wall.

  • Doing this ensures that you get a tight fit next to the wall with a solid 2" of foam and eliminates any air gaps.
  • The grooves of the panels should always be at the bottom of the 4' dimension and to the right on the 2' dimension.  
  • Place the panel with the 4' length against the west wall.
  • Successive panels to be placed in this row now only need the tongue along the 4' dimension trimmed.
  • Continue placing trimmed panels until you get to the east wall. You will most likely need to cut the final panel in this row to fit it in place. 
  • Place the PEX tube in the panel at the required separation points per the specifications of the HVAC designer. Installing the PEX should be a one person job using an uncoiler to hold the PEX tubing.   

TIP: When you make a turn, ensure the PEX is fully seated in the outside radius of the PEX on the knobs before beginning or continuing a run.
