Noistop Steel
Modular steel sound barrier with rockwool core
About Noistop Steel
Noistop Steel from ROCKWOOL is a modular acoustic fence with a galvanised steel frame, a core of sound-absorbing stone wool and a wear-resistant PE netting finish. The combination delivers 22 dB sound insulation (EN 1793-2, class B2) and 8 dB absorption (EN 1793-1, class A3). The fence is fully maintenance-free, fire-resistant thanks to the mineral stone wool and withstands wind loads up to 2.49 kN/m². Modules slide between galvanised posts in heights of 45 to 100 cm (stackable) and in galvanised steel, anthracite (RAL 7016) or jet black (RAL 9005).
