Project Information
The primary challenge in this Chicago home was overcoming the cold transfer from the existing concrete slab beneath the carpet. Concrete is an excellent thermal mass, but without heating, it acts like a heat sink, drawing warmth away and leaving the bedroom floor persistently cold—a major discomfort, especially during the long Chicago winters.
The homeowner required a solution that was safe, effective, and compatible with stretch-in carpeting, which ruled out many traditional heating systems. WarmlyYours recommended the Environ™ Flex Roll, a specialized, low-wattage system perfect for floating floors and installations beneath carpet or laminate. The system was designed to cover 188 sq. ft. of the bedroom floor, effectively creating a massive, evenly heated surface.
Installation was straightforward, involving laying the uncoupling membrane (not explicitly listed but required for concrete/carpet installs) and then placing the self-adhering Environ™ Flex Roll mats directly over the heated area, followed by the carpet underlayment and carpet. The result is a quiet, reliable, and energy efficient heating upgrade. The system is controlled by the programmable nSpire Touch Thermostat, allowing the homeowner to set precise schedules and temperatures for maximum comfort and minimal energy consumption. This installation successfully transformed the bedroom into a true retreat.
