METHOD OF PROTECTING A PLASTIC PIPE IN PE INSULATION PENETRATING WALL AND FLOOR ACCORDING TO ETA-17/1061
1 - flexible or rigid wall with a thickness of B = min. 100 mm
2 - plastic pipe, diameter "D" and pipe wall thickness "t"
3 - PE foam insulation, thickness "g"; nominal density of 30 kg/m3
and reaction to fire class E according to EN 13501-1
4 - the gap between the pipe insulation and the partition with the
maximum width a = 30 mm, filled with mineral wool with a density of min. 60 kg/m3
5 - Piro Multitube PM (inside) with dimensions [h x s], centrally located inside the wall
6 - cable tie or adhesive tape
7 - gypsum mortar with a thickness of g1 = min. 5 mm

1 - reinforced concrete floor with thickness B = min. 150 mm
2 - plastic pipe, diameter "D" and pipe wall thickness "t"
3 - insulation made of PE acoustic foam with a thickness of = 6 mm
4 - Piro Multitube PM [h x s] mm, placed inside the floor,
at a distance of 15 ± 5 mm from the underside of the floor
5 - cable tie or adhesive tape
6 - the space between the floor and the installation, filled with cement
mortar approx. 25 mm

Steps 1 - 5
Read in the table the length of Piro Multitube PM for the given diameter of the pipe, measure it and cut it with a knife.
Wrap the cut tape around the pipe insulation. Follow strictly the number of wraps given in the table.
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 - central position along the wall axis or 15 ± 5 mm from the bottom of the floor.
Fill the space between the pipe and the partition with cement mortar in case of plasterboard fill the space with mineral wool with a min. density of 60 kg/m3 and fill with gypsum mortar with a thickness of min. 5 mm.
Mark the completed penetration seal with the attached label, mark Piro Multitube PM on it, enter the date and name.
