METHOD OF PROTECTING A PLASTIC PIPE IN FEF INSULATION PENETRATING WALL AND FLOOR ACCORDING TO ETA-17/1061
1 - rigid wall thickness B = min. 100 mm
2 - plastic 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 a = 30 mm, filled with mineral wool with a
minimum density of 60 kg/m3
5 - gypsum mortar with a thickness of g1 = min. 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, thickness B = min. 150 mm
2 - plastic pipe, diameter "D" and pipe wall thickness "t"
3 - insulation made of flexible elastomeric foam (FEF) with a thickness of "g"
(continuous insulation)
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 or mineral wool with a minimum density of 60 kg/m3.
Mark the completed penetration seal with the attached label, mark Piro Multitube PM on it, enter the date and name.
