If you love your existing floors but wish they were warmer, Warm Your Floor is pleased to offer our customers an ultra-efficient, affordable, and easy-to-install electric radiant floor heating system from MP Global Products: QuietWarmth® radiant heat film for under subfloors.
Warm your existing floors without having to remove tile or pull up carpet. Even warm hard-to-heat floor types such as nail-down hardwood that aren’t compatible with most radiant heat products. Until now!
How does it work?
QuietWarmth under-subfloor radiant heat film installs easily between your existing floor’s joists. It’s best for anywhere the joists can be easily accessed from a garage ceiling or a basement or crawl space. QuietWarmth features a patented ultra-thin conductive ink technology that delivers low-cost heat to nearly any floor type from the joist bay beneath. A sensor installed in the subfloor combined with a thermostat will help keep your floor at your optimum temperature.
The QuietWarmth® under-subfloor system is available in two voltages (120V and 240V) and in 16 inches to accommodate the most common joist bay spacing.
Simple to Install
Installation is easy. Simply nail or staple each panel of heating film at least every 12 inches to the side of each joist (not to the subfloor itself), leaving a 2” overhang beneath the subfloor. To better fit your space, QuietWarmth film can be cut with scissors to length at each 12-inch increment. Ask a licensed electrician to connect the lead wires to a thermostat. We recommend installing a programmable thermostat with your new electric radiant heating system for maximum efficiency and comfort. Finish the installation with a layer of thermal insulation over the heating panels.

I’m purchasing a new home that has a crawl space. I’m trying to determine if the subflooring is too thick for your product or if it will still sufficiently warm the above floors. How thick can the subflooring be?
matthew@warmyourfloor.com says:
Hi Melody,
A subfloor greather than 1/2″ thick is probably going to start reducing the amount of heat the reaches the finished floor.
You’ll want to try and keep it to 1/2″ or less if possible.
Kevin Burns says:
Hi.
Wow, what a great product! My subfloor, which is accessible from my crawlspace is either 5/8″ or 3/4″ plywood and then there is standard ceramic tile on top, which is the bathroom floor. Total thickness of all material is not more than 1.00″ Is there a model that would be a best fit for my application and what is more cost effective to run, 120v or 240v and is there much of a initial cost difference between them. Lastly, what is the power consumption on both, as I’m trying to figure out just how much these will impact my electric bill.
Joey Henke says:
We have an instance where I will have access from above to install your product while the subfloor is removed and replaced. Can your product be installed from above and then the subfloor installed after?
Paul P says:
I have metal lattice joists 24” apart. Can I use this product?
Pam Cifrulak says:
We only have 3 open bays which are 8 ft. runs, the others have plumbing drains, feed lines or a heat duct. Would this provide enough warmth for a 13’ x 8’ bathroom?
matthew@warmyourfloor.com says:
Hi Pam,
The underfloor products for joist bays will work to heat the floor area directly above mats.
But the heat only radiates about 1.5″ from the heated area so it will not eventually fill the entire floor surface with heat.
If you’re trying to heat the room itself, these joist products may be able to achieve that, but they are not designed for that purpose.

Randy Hermann says:
Is this product rodent resistant? I pulled out the subfloor fiberglass insulation and there was significant evidence of mouse activity between the insulation and subfloor. Any recommendations for dealing with that issue along with the QuietWarmth installation?
Thanks
matthew@warmyourfloor.com says:
Hi Randy,
No specific rodent “deterrent” but the QuietWarmth mats are a plastic film, should not be attracting any rodents to the joists.
The SunTouch mats use an electric cable with foil that may be more durable if you’re concerned about longevity.
Both are great products though and you won’t be disappointed with either.
Matt says:
I have a an older home that has two subfloors, and tile. If I had to guess about 2 inches of thickness. Would this product heat the floor?
matthew@warmyourfloor.com says:
Hi Matt,
2 inches is a pretty thick mass to heat for these retro-fit films.
This would likely still heat the floor but it could take a considerable amount of time to get warm to the touch.
QuietWarmth states the total insulation value of the sub-floor and finished floor must not exceed R-11.
If you can verify the total insulation value of everything above the film is below R-11 then this should work for you.
Let us know if you need anything else.
Thank you, Matt!
Tam Ng says:
Can other type of insulation be used rather than fiberglass?
matthew@warmyourfloor.com says:
Hi Tam,
QuietWarmth does not specify the insulation must be fiberglass.
They only specify that proper joist bay insulation be used, that is a non-flammable material, and a minimum of 3/4″ thick.
richard marcus says:
we are trying to provide some infra red heat for a bathroom for a client.
there is thin mud layer and wood floors
we have full access to the basement.
will your system be right for this application
matthew@warmyourfloor.com says:
Hi Richard,
If you have access to the joist bays below the floor then this is the product to use.
The mats simply install into the joist bay and then are insulated underneath to help direct the heat upward to the floor above.
Let us know if you have any more questions.
Thank you, Richard!
Robert Brill says:
Can retrofit panels come into contact with existing PVC drains, pec water lines or metal heating ducts
matthew@warmyourfloor.com says:
Robert,
The manufacturer states the retrofit mats should not come in contact with any plumbing or ductwork when installed.
They advise you two have the mat stop before and ductwork or plumbing, then have another separate mat begin on the other side.
Randy Hermann says:
Is there a minimum clearance from metal such as ductwork or copper supply lines?
matthew@warmyourfloor.com says:
Hi Randy,
QuietWarmth does not specify how far away to stay from ductwork or copper lines.
SunTouch mentions just to stay 6″ away from heat-sensitive objects like toilet rings, flexible ducting, etc.
In general, you want to make sure you have enough space to properly install the mat and access it again if needed.
Let us know if you need anything else. Thank you, Randy!
