METHOD OF PROTECTING AN EXPANSION JOINT IN WALL ACCORDING TO ETA-17/1059
1 - rigid wall, thickness B ≥ 150 mm, density ≥ 600 kg/m3 and D = 5 ÷ 60 mm
2 - mineral wool with a density of not less than 120 kg /m3
6 - Piro Acrylic Sealant AC120, applied on both sides of expansion joint,
thickness t2 ≥ 0.4 mm

1 - rigid wall with a thickness of B ≥ 150 mm, density ≥ 600 kg/m3 and D = 6.5 ÷ 100 mm
2 - mineral wool with a density of not less than 80 kg/m3
6 - Piro Acrylic Sealant AC120 placed on one side of the expansion joint,
thickness t2 ≥ 1.6 mm
Technical drawing 2
Fill in the expansion joint in
wall with mineral wool boards
with a minimum density of
120 kg/m3 and a thickness
equal to the width of the
partition.
Steps 1 - 4
By using a putty knife, apply
a 0.4 mm layer of Piro Acrylic
Sealant AC120 layer on the wool.
Piro Acrylic Sealant AC120
layer should be applied equally
on both sides of the partition.
Properly protected
