Lo thickness, Engaged in air floor heating "Standard" can be schematized as follows:
- Room to pass plumbing and electrical, About 5 8-cm. Before laying the insulation for underfloor heating systems must be leveled with a "pre-screed", preferably with loose insulating material (cork, perlite, expanded clay, etc.). If there is not enough space, you can opt for a "channels"Passing along the walls, at the same level the radiant system.
- + Insulating pipes = From the 3 5,5 cm. This value depends on how much insulation is placed under the pipe; this thickness is given by the dispersions that there are from the floor down (local open, closed cellar, embankment, heated room)
- Screed, Which can bind by 3 cm, with self-leveling systems type quick-drying, up to 4,5 cm for traditional solutions. In dry systems, the floor can be placed on the system, dry.
- FinishingOn average by 0,8 to 3 cm (tiles, parquet, terracotta).
So in a typical situation, to work in good condition, you need a total of about 15 cm. The choice of the "channel" side to pass the water pipes and electrical permits to work in about 8 / 10 cm, but increases the cost side plant water and electricity.
In plants lowered dry you can go down to a total between 3 / 5 cm, but we must make sure that the insulation placed under the pipe is sufficient to meet the leakage requirements prescribed by the regulations.
