Below listed floor covering materials can be used with lowest
thermal conductivity:
Tiles/marble/granite
Laying in screed (30-50 mm)
A
1. Tile floor covering (tiles or natural stone)
2. Adhesive
3. Watertight layer (optional for wet areas)
4. Special screed for underfloor heating systems (30 – 50 mm)
5. T2Blue heating cable
6. Metal/mesh
7. Plastic foil
8. High density polystyrene insulation (thickness 30 – 50 mm)
9. Subfloor construction (concrete, tiles, wood, PVC, ...) without
thermal insulation
Laying in self leveling compound (15-30 mm)
B
1. Tile floor covering (tiles or natural stone)
2. Tile adhesive
3. Watertight layer (optional for wet areas)
4. Special (self-levelling) mortar for underfloor heating
systems (≥ 15 mm)
5. T2Blue 10 W/m
6. Metal/mesh (optional only needed for wooden
combustable subfloors)
7. Existing floor (tiles, wood, PVC, ...) with thermal insulation
