Description: This radiant overpour fastening system allows contractors to install heating pipe in overpour and concrete installations. The RAUPEX SPEED O2 barrier pipe with hook-and-loop wrap is walked on to the RAUPEX SPEED mat without the use of specialized tools. The mat features an adhesive backer that attaches to a range of different thermal insulation, concrete, and plywood materials without penetrating the surface, thus protecting thermal, vapor, and sound-insulation properties. Pipe can be detached and repositioned, and the system can be installed in concrete slabs, suspended slab, or thin slab overpour projects.
