Installation

The industrial system can be realised in two ways, first as a flat

system, the second (and preferred) by exploiting the presence of

the electro-welded mesh.

•

Install the expansion edge strip;

•

If deemed appropriate, lay a sheet of polyethylene on the

bottom to protect the insulating panel;

•

Install the INDUSTRIAL panel starting from the side walls

and bring the panels together by using the abutting edges;

If you choose the flat system proceed as follows:

•

Install clip rails every 200 cm; fix the bars to the INDUS-

TRIAL panel with the nails provided (3 per bar, one every

100 cm);

•

Install the pipe, realising the circuits as per the installation

diagram: the type of laying to use is "serpentine coil", with

installation centre distances based on the diameter of the

pipe and the consequent minimum radius of curvature (the

most common type requires a centre distance of 200 mm

with 20-mm pipe);

•

Lay the (first) electro-welded mesh;

•

Lay any other electro-welded meshes;

If you choose the mesh system proceed as follows:

•

Lay the (first) electro-welded mesh;

•

Above the electro-welded mesh, install clip rails every 500

cm; fix the bars to the mesh with suitable zip ties (3 as per

bar, one every 100 cm);

•

Install the pipe, realising the circuits as per the installation

diagram: the type of laying to use is "serpentine coil", with

installation centre distances based on the diameter of the

pipe and the consequent minimum radius of curvature (the

most common type requires a centre distance of 20 cm

with 20-mm pipe); fix the pipe to the mesh with the zip ties

provided, one every 100 cm, in order to avoid the pipe lift-

ing during casting;

•

Lay any other electro-welded meshes;

After installing the pipe, proceed with checks of the system, the

casting of the screed and first start-up:

•

Perform the leak test;

•

Proceed to pour the concrete screed (be careful not to turn

the pump sideways to the pipes to avoid pulling them).

•

After spreading and levelling the screed, proceed to making

structural cuts;

•

Carry out screed heating tests per UNI 1264 and/or as indi-

cated by the screed supplier.
