Home / Electric Systems
The Inscreed Cable System is designed for use within a screeded floor construction.
The Warmup Inscreed Cable is designed to be placed within a screed of at least 50mm in thickness. The exact floor build up depends on the insulation materials in the subfloor – please see the installation manual for full details:
