1 - reinforced concrete floor with a thickness of B = min. 150 mm
2 - metal pipes with a diameter D1, D2 and a pipe wall thickness t1, t2
2a - plastic pipes with a diameter of D4, D5 and a pipe wall thickness of t3, t4
3 - Tubolit PE insulation on metal pipes, thickness "g" (continuous insulation)
4 - small cable, diameter D3, covered with PiroCoating on length L = min. 300 mm,     
     thickness a1 = min. 1.2 mm
5 - cable tie or adhesive tape
6 - Piro Multitube PM [h x s] mm band, placed inside the floor, at a distance of 15 ± 5 mm       from the underside of the floor
7 - PiroCoat I on metal pipes with PE insulation, length L = min. 300 mm
     and thickness g1 = min. 1.2 mm
8 - the space between the floor and the installation, filled cement mortar, approx. 25 mm.

Secure the Piro Multitube PM with a cable tie or adhesive tape and slide it inside the partition. Location of the tape inside the opening - 15 ± 5 mm from the bottom of the floor.

Remove 300 mm of insulation from the pipes on both sides. By using a brush apply PiroCoat I on a pipe so that a ring with a width of min. 300 mm and a thickness of min. 1.2 mm is created.
