METHOD OF PROTECTING A METAL PIPE IN FEF INSULATION PENETRATING WALL AND FLOOR ACCORDING TO ETA-17/1061
1 - rigid wall thickness B = min. 150 mm
2 - metal pipe, diameter "D" and pipe wall thickness "t"
3 - continuous insulation made of flexible elastomeric foam (FEF),
thickness "G", nominal density 45 - 70 kg/m3 and reaction to fire class
BL-s2, d0 according to EN 13501-1
4 - the gap between the pipe insulation and the partition with a maximum
width of u = 25 mm, filled with mineral wool with a density of min. 60
kg/m3 and closed with gypsum mortar with a thickness of min. 5 mm
or filled cement mortar
5 - gypsum mortar with a thickness of g1 = 5 mm
6 - Piro Multitube PM (inside) with dimensions [h x s], centrally located inside the wall
7 - cable tie or adhesive tape

1 - reinforced concrete floor with a thickness of B = min. 150 mm
2 - metal pipe, diameter "D" and pipe wall thickness "t"
3 - continuous insulation made of flexible elastomeric foam (FEF),
thickness "G", nominal density 45 - 70 kg/m3 and reaction to fire
class BL-s2, d0 according to EN 13501-1
4 - Piro Multitube PM (inside) [h x s] mm; placed in distance l = 15 ± 5
mm from the underside of the floor
5 - clamp band or adhesive tape
6 - the gap between the pipe insulation and the partition with the
maximum width u = 25 mm, filled with cement mortar

Steps 1 - 5
Read in the tables the length of Piro Multitube PM for the given diameter and the type of 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 tables.
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.
Mark the completed penetration seal with the attached label, mark Piro Multitube PM on it, enter the date and name.
