he Warmup Electric Radiant Heat StickyMat System is a series of small, threefoot wide mesh fiber mats that are extremely durable and designed to be installed under both tile and stone.

Warmup StickyMats have a thin, dual flouropolymercoated heating wire that measures less than an eighth of an inch thick and does not negatively impact floor heights like other cables do. The mats have a dualadhesive, doublesided tape as well as a pressuresensitive adhesive on the entire mesh. The adhesive allows the mat to adhere to the subfloor, resulting in a fast installation. The mats can be repositioned numerous times without losing their adhesive capabilities.

StickyMats can also be combined in a patchwork and to customize the coverage to the shape of your room.

StickyMats are available in ten sizes:
From 3’ x 3’ to 3′ x 10′
From 4′ x 3′ to 4′ x 10′
he Warmup heating mat consists of a twin conductor resistanceheating element woven onto a fiberglass mat. The heating wire measures less than 1/8” and is insulated with Fluoropolymer (FP) with high dielectric strength and high temperature properties.

The conductors are covered by a metallic sheath providing additional mechanical strength and a ground path. A final outer jacket of Fluoropolymer is given to make it sturdier and provide corrosion protection.

Prepare the Subfloor:

It’s super important that you inspect your subfloor for damage, debris, or sharp objects. All nails and screws should be countersunk and the floor thoroughly cleaned.

One major benefit of installing the Warmup StickyMat is that will not dramatically change the height of your flooring. Floor height concerns come into play at doorways or when your room meets another room. In most cases, with the addition of a 1/4 underlayment, the Stickymat heating mat, thinset, and 3/8” tile, you are usually pretty close ¾” height, which is perfect for meeting hardwood flooring or carpeting.

Tip: If the floor heights are off, chamfer the higher flooring material, or install marble thresholds at the doorways.

Ensure that the subfloor is smooth, dry and free from dust. If reusing an existing subfloor I take the time to refasten the old subfloor with screws to ensure a solid attachment, and to resist squeaks and movement.

Visually check that there are no objects on the floor, such as popped screws or nails that might damage the heating mat.

Tip: If you plan on using a level compound to deal with slanting floor, ensure that the compound has properly cured prior to installing your StickyMat system.
A lot of contractors do not use thermal insulation when installing radiant heating — that is a BIG mistake. I was one of them, and the reason was, I simply did not know that using thermal insulation makes your system heat up faster and prevent heat loss from below.

I now use Warmup Insulation Boards [WIB] for floor heat installations like this. WIBs can be used as a tile backer board underlayment on your concrete slab or wood subfloor. WIBs is made from extruded rigid polystyrene foam. The key behind the success is the rigid blue core, which is totally waterproof and requires no additional moisture barrier.

WIBs help reflect heat upwards, and prevent heat loss into the subfloor or cold slab. WIBs provide a 92% thermal break from the cold subfloor and ensure that your floor heating system operates at the highest and most efficient levels. That’s something that not only helps me sell these systems to my clients, but makes people feel like they are using electricity efficiently and getting the most out of their radiant heat system.
