|Schluter® DITRA-HEAT Membrane Features||
DITRA-HEAT provides uncoupling through its geometric configuration, which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface.
DITRA-HEAT features a polypropylene composition which protects the substrate from moisture penetration. This is particularly important in bathrooms, kitchens, and any environment that may be affected by moisture.
Vapor Management The free space on the underside of DITRA-HEAT provides a route for excess moisture and vapor to escape from the substrate that could otherwise cause damage to the tile covering above. Support/Load Distribution Loads are transferred from the tile covering through DITRA-HEAT's column-like mortar structures to the substrate. Since DITRA-HEAT is virtually incompressible within the tile assembly, the advantages of uncoupling are achieved without sacrificing point load distribution capabilities.
|Thickness||DITRA-HEAT 1/4"; DITRA-HEAT-DUO: 5/16"|
|Standard lengths||2'7", 33', 41'1"|
|Custom lengths||Any 1' increment from 6' up to 38'|
Using a thin-set mortar that is suitable for the substrate, apply the thin-set mortar (mixed to a fairly fluid consistency, but still able to hold a notch) using a 1/4" x 1/4" square-notched trowel.
|Apply DITRA-HEAT or DITRA-HEAT-DUO to the floor, fleece side down. Solidly embed the matting into the mortar using a float, screed trowel, or DITRA-ROLLER, making sure to observe the open time of the bonding mortar. If the mortar skins over prior to matting installation, remove and reapply.Note: It may be helpful to back roll the end of the matting before installation, or place boxes of tile on top of the matting after installation, to avoid curling.|
|Lift up a corner of the matting to check coverage. Proper installation results in full contact between the fleece webbing and the thin-set mortar. Note: Coverage may vary with mortar consistency, angle at which the trowel is held, substrate flatness, etc. If full coverage is not achieved, remove and reapply, making sure to verify proper mortar consistency and application.|
|Abut end and side sections of adjacent sheets. Note: Aligning the studs on the top of the matting during installation can help make subsequent heating cable installation easier.|
Estimated thin-set coverage.
|Before the heating cable is removed from the spool, conduct the first set of required tests and record values in the heating cable tests log in the installation manual. If a break or damage is detected during the tests, contact Thermosoft customer support.|
|Thread the heating cable cold lead through a conduit (where required by code) from the base of the wall to the thermostat electrical box. Floor temperature sensors may not be threaded through the same conduit as the cold lead.|
|Mark where the cold/hot splice will be placed, cut the DITRA-HEAT or DITRA-HEAT-DUO matting, and insert the splice. It may be necessary to temporarily secure the splice to the floor with thin-set mortar or adhesive (hot glue). Once the heating cable cold lead and remote sensors are threaded to the thermostat electrical box, install a metal protection plate at the base of the wall. This will help prevent any damage from fasteners (e.g., nails, screws, etc.) in the future.|
|Embed the heating cables between studs, at a spacing of 3 studs (3-1/2"). Closer spacing may result in overheating and damage to building structures. A wider spacing (e.g., 4 studs) will not provide sufficient power to warm the floor to the desired temperature. Exception: a two-stud spacing is used when connecting the 240 V cable to a 208 V power supply.|
|Use care not to damage the cables during installation, particularly before the cables are embedded in the matting.|
|The maximum allowable length of a single run is 5 ft.; the cable must be turned or a u-shaped "jog" created at this point (see image).|
|Install the thermostat sensors evenly spaced between two cable runs, at a distance of at least 24" from the wall. Mark the sensor location on the DITRA-HEAT and cut the matting to recess the sensor. It is recommended to temporarily remove the heating cable from the area while cutting the matting. It may be necessary to temporarily secure the sensor to the floor with thin-set mortar or adhesive (hot glue). Embed the sensor wire in the matting without overlapping or crossing the heating cable.|
|Once the heating cable and floor temperature sensor installation is complete, retest and record values in the heating cable tests log.|
Waterproofing: The following 4 steps are required for waterproofing only.
Note: While the heating cable is protected by the DITRA-HEAT and DITRA-HEAT-DUO matting, be careful when applying the mortar to not damage the cable with the notched trowel. At the joints, fill the matting with unmodified thin-set mortar, approximately 8", centered over the joint.
|Comb additional unmodified thin-set mortar over the joint using a 1/4" x 3/16" V-notched trowel or a 1/8" x 1/8" square-notched trowel.|
|Apply 5" wide KERDI-BAND, centered over the joint. Using the flat side of the trowel, firmly press the banding into the mortar to ensure 100% coverage and to remove excess mortar and air pockets.|
|At all wall junctions, apply KERDI-BAND as described in steps 1-3, centered where the wall and floor meet. In some applications the vertical section of the floor/wall transition will not accept a bond to unmodified thin-set mortar. Connections to such elements can be achieved using KERDI-FIX sealant and bonding compound or suitable trowel-applied waterproofing materials, such as those that require atmospheric moisture to cure (e.g., urethane sealant). Note: KERDI-BAND must lap DITRA-HEAT and DITRA-HEAT-DUO at seams and at floor/wall transitions by a minimum of 2" in order to maintain waterproof integrity.|
Note: While the heating cable is protected by the DITRA-HEAT and DITRA-HEAT-DUO matting, be careful when applying the mortar to not damage the cable with the notched trowel.
Tile can be installed over DITRA-HEAT and DITRA-HEAT-DUO immediately; no need to wait for the mortar to cure. Fill the matting with unmodified thin-set mortar and comb additional mortar over the matting using a trowel that is appropriate for the size of the tile.
|Solidly embed the tiles in the setting material, making sure to observe the open time of the bonding mortar. If the mortar skins over prior to tile installation, remove and reapply.|
|Periodically remove and check a tile to ensure that full coverage is being attained.|
Once the tile installation is complete, retest the heating cable and record values in the heating cable tests log.
Allow the assembly to cure for 7 days after grouting before putting the floor warming into service.

Dan was very helpful and had great problem solving ideas. The exchange was not rushed and I felt well supported and informed in the purchasing process. Thanks Dan!
I was stuck in an installation and reached out to my account manager David Kaempf who immediately transferred me to Tech Support. Unfortunately I got the voice mail. and I tried calling back. No sooner did I could scroll through my phone, I got a message from Dan Gutierrez from Tech Support. I called him and he walked me through and troubleshoot my my problem. He made me feel like I was part of the team AND THAT SAVED THE DAY. Big kudos guys, now I no why I've been a member since 2008!
Mitch you've been a pleasure! I have not yet installed my floors but look forward to installing your heat mats in next two weeks or so
Dan was AMAZING! I had a question in online chat, and he called. Not only did he save me some money, we are happy to do business with him in the future!
The gentleman I spoke with was understanding of my problem and discussed solutions. Not rushed and listened respectfully to a lay persons explanation. I will purchase from this company. Thank you dr R
I've installed ThermoSoft products under both a marble tile floor and an engineered wood floor within my home over the last two years and am very satisfied with both results. The planning and ordering process is easy and straightforward thanks to an well designed website containing all the needed information combined with live technical consultants. The post installation support is excellent, with Dan Gutierrez addressing some initial technical questions, then following up for two weeks to ensure the product was working to my expectations. It is, and now we are enjoying the comfort of heated bathroom floors during the cold winter months.
dan was helpful
Dan Gutierrez was extremely helpful. He took multiple calls from me and also from my contractors. He was always very kind and informative. I would recommend Dan to anyone needing advice and product information
Dan was awesome. Very helpful. Walked me thru the diagnosis. Thanks!!
Absolute best experience. Love the product, great costumer service. Knowledgeable, expert advice 100% availability, all in all 5 star company. Would recommend always. Bought radiant heating in all my house in upstate NY. After the second winter is over I can say this system is much better than previous regular heating system I had. Heat is distributed evenly throughout the room, which makes for greater comfort and a nice warm feeling when you walk on it. The system is not drying the air like forced air alternative. It does not have "jumps" in temperature from too hot to too cold, instead the temperature is constant all the winter. Bought thermostats in all the rooms so everyone can choose their own "climate". In terms of money, the electrical bill is about the same as with natural gas heating before (I am not factoring the cost of installation, just bill over bill).
I called several times with various questions and every time. Each time I called i was greeted with a kind employee who answered all my questions without making me feel stupid. I have been very pleased with this company and the heating mat was very easy to put down but I had a tile company to put down the tile in my bathroom. This is definitely a 5 star company!
Both the gentleman I talked with were extremely helpful. They were very patient with me as I asked questions that I probably could have had answered through the manual or website. The whole process of working with Thermosoft has definitely been a 5 star experience!! Thanks so much (and stay healthy
Things were ordered close to last minute. I appreciate the fast shipping as my business is on the line. Products came well packaged. The best part was the customer service I received from calling in to ask questions about what I was ordering. Concise & clear information was given making my decision very easy. Thank you Thermosoft. Be using you on more of my jobs!
I was amazed as I called ThermoSoft at 7:00 PM pacific time left a message with their answering service 1/2 hour later I get a call from Doug and I know it's 10:30 pm where he's from. He answered all our questions and helped us figure out what we needed and gave us a good price. We just placed our order with him and will recommend Doug to my brother in-law as he wants to know how the product is after it's all installed.
Felt I was given good, solid buying advise from Dan G. Had some issues with the new Thermostat but was given excellent info and instructions from Dan regarding settings that I was not sure of. Got that new Thermostat up and working in no time and I then advised Dan that I may have to call back from time to time seeing this new one has so many features and needs to dialed in accurately to perform factual readings. Dan Recommended that I should call him back with ANY questions regarding this. He then added his ext.# to his email. Dans help was exceptional!! Signed his mom, Just Kidding, Kevin Scott
Easy and quick to order from and answered questions promptly and precisely before and after purchase.
My electrician recommended ThermoSoft and ordering was really easy! I am excited to have heated floors in my bathroom.
I had a wonderful experience with Thermosoft from start to finish. Doug and the Thermosoft team met with me to talk about their products, go through options for installation, and make sure that the flooring I was using would be compatible. Their customer service is top notch.
I have a problem and spoke to two different technicians. Each pulled up my project on their data base and was able to help. My experience with your personal has been very positive! Thx
I have been using Thermosoft heat mats in my tile business for years. I like that you stand by your products and have a great support team. If I need help I get to talk to knowledgeable people who will follow through and call back! Keep up the good work
My overall experience with Thermo Soft has been nothing short of "Excellent". The website was easy to maneuver through. Once I found a product that would be viable for my situation, I had a little chat session with the Tech services...namely Dan G. Dan was very informative and helped me through the process of making the right choices. As we corresponded via email, he was quick to respond. That impressed me! I deal with many clients, reps and vendors and it's one of my pet peeves waiting and waiting on a response. Maybe I'm to impatient...Anyway, thank you Dan and Thermo Soft for the great service and product.
You've been very helpful Mitch!
dan was excellent, he responded to my phone call in a timely fashion. He was helpful and willing to give advice..My experience was very good...
Dan was the on-call technician when we were installing our Thermofloor pads, on a Sunday. He responded to the call promptly, was patient and helpful, and made himself available for further questions. I texted him at least one more time on Sunday, and got a prompt, helpful response. I also emailed him, and got a response the next day, and he checked in a couple more times with me, unprompted, to see if I had any more questions. He really gave us first-rate support.
Pretty good service, with timely delivery!
Appreciated prompt response and assistance for a DIYer.
Reps were very helpful. Great personal service and prompt delivery of the items I ordered.
I called tech support because my thermostat wouldn't maintain the set temperature. Dan walked me through several steps over the course of a couple of days. He always called back when he said he would and emailed to follow up. Once we'd tried several steps he identified it as a faulty thermostat and helped me order a new one. Fantastic guy to work with.
Reps were very helpful. Great personal service and prompt delivery of the items I ordered.
Everything's been great! Thank you!
This was a completely new experience for us and Thermosoft walked us through every step of the way. So thrilled with the product and so grateful for the wonderful customer service.
Mitch has been an awesome person to work with. He has provided helpful information along the way during our selection and order process, helped us figure out the right materials and quantities we needed, was excellent at communicating and following up on open orders, was extremely efficient in getting our order processed and delivered timely and was pleasant to work with. I would highly, highly recommend Mitch to anyone needing assistance with their future ThermoSoft orders!
Like shopping in the 60's, GREAT customer Service. Doug, help me get extra padding for our addition, because of a contractor's error. He went above and beyond what a normal company does in today's market. What great products,ease of installation and SUPER customer service. I called Doug three times with questions and he had an answer right away. THanks goes out to Doug what a great customer service Rep.

Thank you for your patience and you pleasant persistence.
We're adding floor heat under floating laminate to a chilly master bedroom that the furnace doesn't seem to reach. I've previously installed Thermosoft heat in my shop. Heated floors are really pleasant, and look nicer than baseboard.
Outstanding prices and sale and large selection of products that make it easy to adapt to many applications.
That was a lot of help, thanks for guiding me through the process!

Customer service was great.
I always come to you!
The products I received appear to be made locally (USA) which is important to me. My customer service representative (Doug) is very technically adept and efficient. I interact with a large variety of people and care more about competencies than personalities. It was very refreshing to interact with a supplier that genuinely strives for excellence.
I appreciate your help!

You guys have been great! It's been good working with you. This project has taken a long time!
Customer service was polite and helpful and promised to exchange a product for a bought by mistake, I purchased additional products from them and then they never sent return information for the purchase they said I would be able to return. After several emails I have not gotten a response
Everything's been great!
Low pitch, low key, not pushy, and inform the customer. I like that very much! I have not however received the CAD layout design for the thermosoft floor heating. A followup email was not answered. Otherwise everything thing else was top notch.
This was an easy install, just as David said.... he walked me through thermostat procedures
All the reps I have spoken with have been very helpful and knowledgeable.
You have been been fabulous! Thank you so much for all your help!
