REHAU announces the expansion of its hydronic radiant heating and cooling portfolio with the introduction of the STEPLOC™ radiant panel system, engineered to speed installation while providing greater flexibility in system design.
Designed for radiant floor heating and cooling applications where RAUPEX® O2 Barrier pipe is embedded in concrete or gypsum-based overpours, STEPLOC installs over slab-on-grade, suspended slabs, plywood subfloors, or insulation, making it suitable for a wide range of residential and commercial projects.

Unlike radiant panels with insulation permanently attached, STEPLOC allows engineers to specify the insulation type and thickness required for each project. This approach provides greater design flexibility while helping avoid unnecessary material costs when insulation is already in place or not required.
The system features a durable self-adhesive backing that bonds to concrete, plywood, and foam insulation. Engineered retention knobs securely hold 1/2 in. RAUPEX O2 Barrier pipe without clips, staples, or additional fasteners. Installers simply press the pipe into place until it clicks between the knobs, creating accurate, consistent pipe spacing with less labor.

Each box contains 20 panels covering 278.4 ft² (25.86 m²). Panels are walkable during installation and can be easily trimmed with tin snips or a utility knife to fit virtually any room layout.
By eliminating traditional fastening methods, STEPLOC helps reduce installation time, minimizes installer fatigue from bending and kneeling, and delivers clean, consistent pipe layouts that support reliable system performance.
Whether designing or installing radiant systems for single-family homes, multifamily buildings, or light commercial projects, STEPLOC delivers the flexibility engineers need and the productivity contractors demand.
