METHOD OF PROTECTING A PLASTIC PIPE IN MINERAL WOOL INSULATION PENETRATING WALL AND FLOOR ACCORDING TO ETA-17/1061
1 - flexible or rigid wall, thickness B = min. 100 mm
2 - plastic pipe, diameter "D" and pipe wall thickness "t"
3 - Piro Multitube PM (inside) with dimensions [h x s], centrally located inside the wall
4 - cable tie or adhesive tape
5 - the gap between the pipe and the partition with a maximum width of
a = 30 mm, filled with mineral wool with a density of min. 60 kg/m3
6 - gypsum mortar with a thickness of g1 = 5 mm
Technical drawing 1
1 - reinforced concrete floor with a thickness of B = min. 150 mm
2 - plastic pipe, diameter "D" and pipe wall thickness "t"
3 - mineral wool with a density of min. 50 kg/m3 (continuous insulation)
4 - PiroCoat A paste on both sides of the floor; length a1 = min.
50 mm, thickness g1 = min. 0.6 mm, width a2 = min. 50 mm,
thickness g2 = min. 0.6 mm
5 - Piro Multitube PM [h x s] mm, placed inside the floor,
at a distance of 15 ± 5 mm from the underside of the floor
6 - the space between the floor and the installation, filled
cement mortar, approx. 25 mm

If necessary, it is possible to continue the mineral wool insulation along the entire length of the pipe:
1 - mineral wool with a density of min. 50 kg / m3 (continuous insulation)
2 - PiroCoat A on both sides of wall; length a1 = min. 50 mm, thickness
g1 = min. 0.6 mm width a2 = min. 50 mm, thickness g2 = min. 0.6 mm

Steps 1 - 6
Read in the table the length of Piro Multitube PM for the given diameter of the pipe or bundle, measure it and cut it with a knife.
Remove the insulation from the pipe, wrap the cut tape around the pipe under the mineral wool 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.
Put mineral wool insulation on the pipe so that it covers the tape. Fill the space between the pipe and the partition with cement mortar or mineral wool with a minimum density of 60 kg/m3.
By using a putty knife apply PiroCoat A on the partition and on the pipe insulation so that a ring with a width of min. 50 mm and a thickness of min. 0.6 mm is created.
Mark the completed penetration seal with the attached label, mark Piro Multitube PM and PiroCoat A on it, enter the date and name.
