FloorHeat Radiant EasyFloor 1.33-ft x 16-in Grid module 1.77-sq ft

Build clean, fast, and predictable hydronic radiant floors with interlocking Grid Modules that snap together on slab or over wood subfloors-no wet topping or heavy grooved boards required. Each 16 x 16 x 1 in. grid provides built-in tubing channels at 8 in. on-center to route and protect 1/2 in. or 5/8 in. PEX (1/2" PEX-AL-PEX recommended), helping deliver even surface temperatures while allowing lower supply water temps for efficiency. The modular layout supports straight runs, smooth turns, and room-by-room customization for kitchens, baths, basements, additions, and whole-home projects. Pair the grid with our Aluminum Heat Transfer Plates to spread heat quickly, evenly, and reduce striping, then add our Reflective Foil underlayer to minimize downward losses. For stable comfort, top with a cement-board thermal mass layer before your finished floor covering (follow flooring manufacturer guidelines). This dry, low-mess approach is ideal for remodels and multi-story installs where speed, cleanliness, and height control matter. Lightweight, durable, recycled polymer grids resist moisture, mold, and mildew and cut easily with common tools for on-site fitting. The organized channel pattern keeps tube placement consistent for balanced loops and straightforward commissioning. Use alone or as part of a complete radiant package with our Heat Plates, Reflective Foil, and Pre-Assembled Distribution/Control Panel for a professional, extremely high efficiency, and serviceable result.
