RPM-V1 Radiant Positioning Mat with Holes 5/16" x 20" x 44" (6.11 Sq Ft)
Now with holes for easier installation on wood (NO staples required) and the ability to use lower cost adhesive on concrete. RPM-V1 Mats make the installation of floor heating cable fast and easy when using self-leveling mortar. RPM-V1 Mats are 20" x 44" and made 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 of your choice (not included) 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 lab tested and approved heavy rating with a lower profile than 1/4" backer board. 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 testing. Studs are 1/2" in diameter and spaced at 1".
