This project transformed a massive, cold 1,815 sq. ft. basement in Lake Harmony, PA, into a warm, usable, and inviting living area. The primary challenge was heating such a large, below-grade space efficiently, especially under the chosen floating laminate flooring. WarmlyYours’s Environ Flex Roll provided the perfect in-floor heating solution, delivering consistent, deep warmth and adding significant comfort and value to the home.

A Solution for a Large-Scale Challenge
The goal for this expansive 1,815 sq. ft. lower level was a total transformation. Like many basements, it suffered from a persistent, ambient cold, making the concrete slab an uncomfortable surface. The client selected durable click-together laminate for the new floor, a practical choice that can, unfortunately, feel cold underfoot without a floor warming system.
The installer, JP Houster Choice LLC, needed a reliable and easy-to-install system. The Environ Flex Roll was specified as the perfect match. Its foil-based design is engineered specifically for floating floors like laminate, and its dry installation method requires no mortars or self-leveling, which saved significant time and complexity on a project of this scale.
Even though this was the installer's first time using the product, the simplicity of the roll-out system ensured a smooth process. To effectively manage the 1,620 sq. ft. of heated space, the layout was divided into two distinct zones (870 sq. ft. and 750 sq. ft.). Each zone is controlled by its own nJoy WiFi programmable thermostat, allowing the homeowner to heat the large area efficiently. The result was a perfectly heated, comfortable basement, confirmed by the customer’s immediate feedback: "We really love your product."
Featured Products
- Environ™ Flex Roll: Our premier electric floor heating mat for floating floors. The foil-based system provides even, gentle heat for laminate and engineered wood without any messy thinset or adhesives.
- ThermalSheet Insulating Underlayment: This 6mm thick underlayment was installed over the concrete slab. It acts as a powerful thermal break, preventing heat loss into the concrete and directing nearly 100% of the warmth up into the flooring, significantly boosting the system's efficiency.
- nJoy WiFi Thermostat (UWG5-4999-WY): This programmable thermostat offers precise temperature control and can be accessed remotely via WiFi. Its floor sensor ensures the perfect temperature and safe operation.
- nJoin 2.0 Power Module (USG5-4000): For large projects like this one, power modules are used to safely and effectively expand the electrical load that a single thermostat can control, allowing for seamless operation across a vast area.
