Design Flexibility and Superior Comfort for Your Clients

STEP Warmfloor is unlike any other radiant heating system on the market today. The entire 12" wide, self-regulating, semiconductive core allows the entire element to conduct heat, instead of the traditional "heat mat" that relies on small wires or hydronic systems that utilizes tubes of heated water. This creates a more efficient system that requires no maintenance.  

STEP Warmfloor is easy to design around. Our thin (1.2 mm) element requires minimal floor build up. We eliminate the need for boilers and ductwork as well as unsightly radiators and baseboards. The STEP element can also be used under any flooring type, including hardwood.

The use of STEP Warmfloor can contribute points towards the LEED Credits.

The heating element is thin (1.2mm) and flexible, it gets cut on and wired on site for maximum versatility. It’s extremely durable and can tolerate the heavy traffic of a construction site. You can also nail or staple directly into the heating element.

STEP Warmfloor doesn’t use tubes or cables to heat, this means there is a 0% failure rate and it is maintenance free.

Easy Installation Under any Flooring Type

STEP Warmfloor can be installed directly under any flooring type, including carpet and hardwood. The element is safe, low voltage and since it’s self-regulated, it will never overheat. The element will not exceed 85° and will not damage hardwood, engineered wood or laminate floors. You can nail or staple directly into the element.

For installation under tile flooring, the element can be placed directly under thinset, under cement board, under waterproof or uncoupling membranes, it’s compatible with whatever installation method you prefer. For a complete guide on all flooring types, please see our Flooring Options Guide.

If you have any further assistance, our knowledgeable staff is available to answer any question you have before, during or after installation.
