Can you cut any of the Quietwarmth Radiant heat film mats? Well, Yes, you can… All the QuietWarmth mats are ready to go right out of the box, so if you do not need to cut to length to fit your area, you can just unroll and go. But one of the best attributes that makes the QuietWarmth radiant heat products unique from many other traditional wired floor heat products is the fact you can cut the mats to length.

All the QuietWarmth products are made from a conductive ink technology, because of this, it allows for our products to be flexible and thinner than a credit card. And it makes Cutting them is easy for all 3 product applications and they only require a regular household scissors. For Floating Floor applications – the ones labeled “float” on the package – are for floors that float over the subfloor like floating vinyl planks that are 4mm or greater in overall thickness, laminate, floating engineered wood, and floating tile installations like Mohawk’s Fast Tile. The Float mats just require cutting between the dotted lines. Do not cut into the black heating stripe. If a black stripe is cut into by mistake, simply cut off the next black strip between the dotted lines. Each boxed mat comes with 2 colored insulating discs to cover the freshly cut silver bus bar ends. Be sure to cover each side completely with the colored disks.

For traditional tile and glue-down flooring applications – the ones labeled “tile” on the package – are for floors that require thin-set mortar or other adhesives. Just like the Float mats, the Tile mats require cutting across the mat – between the black stripes just as before. After cutting, the Tile Mats do require an additional step. To get a good seal around the cut edge of the mat and to properly create a moisture-tight barrier, Cut back one black heat stripe from both sides of the panel. This will deaden the last stripe so the mat will properly be encased in the membrane. Make sure not to cut into the second black stripe. In the box, the mat comes with the 2 colored insulating disks. On each side, Fold the colored insulating disk over the ends of the silver bus bars – covering these ends completely to avoid electrical leakage. We have placed a link in the description to our video installation instructions and how to fully prepare the Tile mats for installation even after cutting.

Finally, when cutting the QuietWarmth Radiant Heat system for under subfloors – the ones labeled “joist” on the package – are for under subfloors with access below with 16” on center joist spacing. Unlike float and tile versions that you can cut almost any length off as needed, the Joist version is built upon 1ft panel increments. Only cut between the 1 ft panels that are marked “cut here”. Do not cut randomly into any part of the black stripes that are not labeled where to cut. Doing so will disable the mat from working properly. Insulate the cut ends with the provided colored discs – on both of the freshly cut silver bus bar ends

If for whatever reason you misplace or cannot locate the colored insulating discs, you may simply use electrical tape to cover the ends of the cut silver bus bars.

QuietWarmth Peel and Stick radiant heat film for traditional tile can be cut to length only. This white membrane adhered to the film heater is the watertight membrane that will protect the mat from moisture. Please understand that right out of the box the mat is NOT watertight. Now, this does not mean the mats can be used in wet areas like shower floors, it just means it is moisture tight from the adhesives or mortar you will be applying for the tile or floor covering needs. Thoughtfully, the mats have been left “unsealed” right from the factory so any needed cutting can be easily implemented before turning it into a moisture-tight membrane.

So, to customize the length of the mat, Cut the mat between the black heating stripes. Do not cut into a black stripe as that will cause damage to the mat and GFCI tripping at the Thermostat. The next step is crucial in cutting the mat. To get a good seal around the cut edge of the mat and to properly create a moisture-tight barrier, Cut back one black heat stripe from both sides of the panel. This will deaden the last stripe so the mat will properly be encased in the membrane. Make sure not to cut into the second black stripe. In the box, the mat comes with these 2 colored insulating disks for any cutting. On each side, Fold the colored insulating disk over the ends of the silver bus bars – covering these ends completely to avoid electrical leakage.

Finally, the last step of cutting the mat is equally important. Seal the edges of the mat so the mat is moisture tight. What happens if you did not need to cut the mat? No problem, this last step will need to be performed as it was left open with the flexibility to cut to length. So, peel back the bottom release liner on the inside of the flap and adhere the heating element by pressing down firmly. Once the heating element is adhered to the bottom of the flap carefully peel back the upper release liner and press down to seal the edges of the membrane. Do this to both sides of the mat. MAKE SURE TO PRESS OUT ANY AIR BUBBLES AS YOU ARE ADHERING THE TOP FLAP TO THE BOTTOM. Once this is complete, install the QuietWarmth peel and stick mat as per the rest of the instructions.

So as a reminder – There are 3 main steps to cutting the QuietWarmth Peel and Stick Radiant Heat Film for Tile mats. Cut between the black stripes Deaden the last black stripe with an insulated cut back bar Encase the white membrane with the removal of the release liners.

1. Cut between black stripes
2. Deaden the last black stripe with an insulated cut-back bar
3. Encase the white membrane with the removal of the release liners
