The subfloor will need to be prepared as per the instructions of the self-leveling cement (SLC) used. Please note that most self-leveling products require the use of a primer as specified by the SLC company.

Yes, our TempZone Heating Products can be used for heating luxury vinyl tile or luxury vinyl planks in any indoor application.

No, most in-floor heating is designed to be added to new flooring. If you do have existing wood floors you would like to add radiant heating to - it is possible to do so with an under-joist heating system.

The height of the membrane itself is just about 1/4" (7/32").

Yes, Luxury Vinyl Tile (LVT) is typically installed over the embedded heating element using self-leveling cement (SLC). Many people choose to use SLC when installing tile over floor heating.

We do not suggest using thinset to encase the heating wires with LVT, as it is very difficult to get thinset completely flat.

We suggest the heating product be embedded in a minimum of 3/8" of self-leveling cement (SLC). Always check with the manufacturer for specific recommendations.

LVT (Luxury Vinyl Tile), WPC (Wood Plastic Composite), and Solid Core all fall into the category of "vinyl flooring." These vinyl flooring types can be rated for floor heating, but the application will completely depend on the manufacturer's guidelines.
Please look in the installation manual and warranty documents of the LVT, WPC, and Solid Core flooring product that you are interested in to see if and what types of heating are allowed.

As for a list of manufacturers of LVT, WPC, and Solid Core products providing a warranty for their products with radiant heat -- many do provide a warranty for their products when properly installed with floor heating. The list of these is ever-changing, so please be sure to check with the flooring manufacturer for current recommendations.

We suggest removing SPC or WPC flooring before installing the floor heating system over it if possible. If that is not practical, use an underlayment designed specifically for covering these types of floors. Radiant heating can be used with many types of these floors, but check with the flooring manufacturer to confirm that it can be paired with these types of systems.

Yes, if the flooring manufacturer recommends this installation method. In most cases, the heating element will still need to be embedded in self-leveling cement before the flooring is installed.

There are heating systems designed for floating floors, such as our Environ system. However, the flooring must be rigid enough so it does not mold itself to the heating cables over time.

Check the flooring manufacturer's floor heating recommendations. In most cases, the heating system will need to be embedded beneath the flooring. Check for all "flatness" requirements for the flooring you choose. The flattest floors utilize self-leveling cement when installed correctly.

This membrane provides many benefits including speedy installation, uncoupling, crack isolation, vapor management, and load distribution.

1 person found this helpful Was this helpful? Yes No

A decoupling membrane protects the installation from differential expansion/contraction between the substrate and the flooring, relieving almost all shear stresses. Crack isolation protects the installation by isolating the flooring from minor in-plane substrate cracking.

We recommend verifying 3 things with the manufacturer of the flooring product to be heated;

1.) Is the flooring product compatible with electric floor heating?

2.) What is the maximum temperature the flooring product can withstand?

3.) What is the temperature set back recommendation of the flooring product?

No, the tile floor should be installed at the same time as the embedding of the heating cable. 

Was this helpful? Yes No

No, the Prodeso Cable Installation Membrane does NOT eliminate the need for movement joints, including perimeter joints, within the tiled surface.

Was this helpful? Yes No

The most common spacing is 3.75" (3 membrane nodules) between runs of heating cable. Occasionally, systems will be designed with 5" spacing (4 membrane nodules). 

Was this helpful? Yes No

An uncoupling membrane like Prodeso provides a flexible layer between your subfloor and tile, preventing cracks caused by natural floor movement. It also offers waterproofing and vapor management, making it ideal for bathrooms. Plus, the membrane’s studs make cable installation fast and consistent without the need for staples or glue.

The best way is to use our Radiant Floor Heating Quote Builder tool. It’s a great way to get an estimation by simply providing project information like room size and subfloor type.

Typically, an uncoupling membrane like Prodeso will be best for this application because it can be paired with accessories to effectively waterproof the subfloor. 

However, if you have a cement subfloor, then ThermalSheet synthetic cork is a good choice because of its high 1.5 R-value and moisture resistance.
