Video 2 of 2 to illustrate aluminium roller shutter mechanical noise.
Internal security roller shutter, CD40 slats, with nylon noise reduction strips / inserts.
This installation is within a contained space with tiled floors, so the mechanical noise is amplified. This shows as comparison to video 1, the same unit fitted with noise reduction strips.
Roller shutter mechanical noise can be influenced by a number of factors, including slat type, nylon slat inserts, motor speed and shaft diameter.
