The problem is, air is an insulator and Pex directly in contact with wood is a poor conductor. Will a radiant system without aluminum plates work? The best answer is “maybe.” If plates are not used then you are relying on air and the few locations where tubing is in contact with the floor to transfer the heat. So, in our opinion, it’s foolish to save a little bit of money up front and forgo an essential element that will save you money forever. This in turn will save you money every single day that you operate the heating system. We also adhere to the “keep it simple” approach so we only quote components that we believe are truly necessary. Everything we do and everything we quote is for the sole purpose of creating the most energy efficient system possible. We get it! Radiantec considers itself to be an “energy efficiency” company. We get this question a lot because let’s face it, people want to save money. Will a Radiant Floor System Without Aluminum Heat Transfer Plates Work? The basement will get too warm and you won’t get enough heat into the space above. What can happen if you don’t insulate? Since radiant heat will go in all directions, the heat will just as easily go downward. If the ceiling will not be finished, some will wait and see how the system performs and then add the insulation after if necessary. Some will insulate between the joists with fiberglass and then seal the entire underside with rigid foam. You should try to get in a minimum of R-30. If the heat loss downward is entirely wasted to a crawl space, for example, then your insulation method should be extensive. Most people don’t mind if they lose a little bit of heat downward in this scenario. If there is an unheated basement below then you should use R-19. Staple up insulation detail above a crawl space.
There is no need to tape any of the seams. Crete-heat has a built in vapor barrier and is tongue and groove so it snaps together. There is no need for spending extra time bending over and tying the tubing to the mesh or rebar. All you have to do is walk the tubing in place, step it down between the nubs and keep going. This product has nubs on top to hold the tubing in place.

Then, you are stuck with a 1/2″ of true insulation. This is a quick and easy product to install but in this case, quick and easy definitely isn’t the way to go.Ĭrete-heat is the name of one product that many of our customers use. You lose the reflective properties of the material once you pour concrete over it. These products claim a high R-value but most of this comes from its reflective properties. Some promote the use of thin sheets of foil/bubble or an insulating blanket. Typically, we recommended 2″ but some states now require 3″ or R-15.
Extruded or expanded polystyrene (rigid blue or pink board) is the material of choice. Once the vapor barrier is in, you should insulate the slab from the earth.

You should check with your code official for code compliance. Studies show that this may not be effective as other options. 6 or 8-mil Visqueen plastic (polyethylene plastic) has always been the material of choice. On top of your compacted earth or sand, you should install a vapor barrier. Preparing the Concrete Slab for Radiant Floor Heat Vapor Barrier Keep in mind that these recommendations are general in nature and you should always consult your code official for proper installation. Here are some general guidelines to follow. If it is not, you can have a floor heating system that is inefficient, costly to operate, and may not work at all. While it is simple, it is very important to do it correctly. The concrete slab installation is one of the simplest and most efficient ways to install radiant heat.
