1 - floor with a minimum thickness of 150 mm
2 - cable tray
3 - cables with a diameter of max. 21 mm
4 - PiroCoating; on both sides of the floor, length L = min. 300 mm,
depth k = min. 30 mm, thickness g2 = min. 1.2 mm
5 - PiroCoating, on both sides of the floor, with dimensions:
f = min. 50 mm, e = min. 50 mm, g1 = min. 0.6 mm
6 - mineral wool, density 50 kg/m3, thickness w = max. 40 mm
Technical drawing 1
1 - flexible or rigid wall with a thickness of min. 125 mm
2 - cable tray
3 - cables with a diameter of max. 21 mm
4 - PiroCoating; on both sides of the partition, length L = min. 300 mm,
depth k = min. 30 mm, thickness g2 = min. 1.2 mm
5 - PiroCoating, on both sides of the partition, dimensions:
f = min. 50 mm, e = min. 50 mm, g1 = min. 0.6 mm
6 - mineral wool, with a density of min. 50 kg/m3, thickness w = max. 40 mm
Technical drawing 2
Fill the hole in the wall on both sides with mineral wool boards with a minimum density of 50 kg/m³ and a maximum thickness of 40 mm.
Steps 1 - 4
By using a brush, apply a 0.6 mm thick PiroCoating layer on the wool over a length of min. 50 mm from the cable tray.
Apply PiroCoating with a brush on the cables and cable tray 1.2 mm thick layer over the length of min. 300 mm from the partition.
Mark the completed penetration seal with the label. Mark PiroCoating on it, enter the date and the name.
