RPM Mats make the installation of floor heating cable fast and easy. RPM Mats are 20” x 44” and Made in the USA from Heavy Duty 60 mil ABS plastic (80%+ recycled materials) but weigh only 2.0 lbs. Our most popular thickness is 5/16” and has been used to install thousands of WarmWire® projects providing a lightweight, quick and clean option to a traditional backer board and cable guide strap installation. Simply thread the floor heating cable onto the grid between the studs at your desired spacing and it sits safely and securely 1/8” below the top of the studs so your installation is protected from traffic and tools. Once filled with cement leveling mortar your floor has a TCNA tested and approved “heavy” rating with a lower profile than ¼” backerboard. Plus it is lighter weight and installs in half the steps! On concrete slabs, it’s rated “High Performance” as an anti-fracture membrane in TCNA testing plus RPM acts as a thermal break. Studs are ½” in diameter and spaced at 1”.
