METHOD OF PROTECTING A METAL PIPE IN PE INSULATION PENETRATING WALL AND FLOOR ACCORDING TO ETA-17/1061
1 - rigid wall thickness B = min. 100 mm
2 - metal 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 - Piro Multitube PM (inside) with dimensions [h x s], centrally located inside the wall
5 - cable tie or adhesive tape
6 - gypsum mortar with a thickness of g1 = min. 5 mm
7 - 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
8 - PiroCoat I with dimensions: length L = min. 500 mm, thickness
s1 = min. 1.2 mm
Technical drawing 1
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
3 - Tubolit PE insulation on metal pipes, thickness "g" (continuous
insulation) thickness a1 = min. 1.2 mm
5 - cable tie or adhesive tape
6 - Piro Multitube PM [h x s] mm, placed inside the floor, at a distance of
15 ± 5 mm from the underside of the floor
7 - PiroCoat I paste on metal pipes with PE insulation, length L = min. 300
mm and thickness g1 = min. 1.2 mm
8 - space between a floor and installation, filled cement mortar,
approx. 25 mm.

Steps 1 - 6
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.
Remove 300 mm of the insulation from the pipe on both sides of the partition.
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.
Reattach previously removed insulation to the pipe on both sides of the partition.
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 penetration seal with the attached label, mark Piro Multitube PM and PiroCoat I on it, enter the date and name.
