Carpet heating insulation 3mm XPS board ISO74

3mm insulation developed for under-carpet heating. It provides faster warm-up times with a minimal buildup height. The ISO74 has a very high density; it is composed of small closed cells that deliver excellent performance under carpet heating systems. The structure of the ISO-74 prevents heat from being conducted downward, directing all heat toward the floor surface.
