New bearing for stairs achieves soundproofing values of 31 dB

Buers, Austria. Getzner Werkstoffe is introducing its new Sylomer® SB10 bearing for concrete stairs onto the market. With a rate of impact noise reduction of 31 dB, Getzner's solution represents an effective sound control measure for residential, commercial and industrial buildings, which is easy to install. The bearing can support flights of stairs weighing up to six metric tons.

Stairs often transmit disruptive noises into buildings. Impact noise occurs when people pass up and down the stairs, which then propagates via walls and ceilings to adjoining rooms. The new SB10 bearing for stairs from Getzner rectifies the problem. Easy to install and with a rate of impact noise reduction of 31 dB according to ISO 717-2, it represents a significantly superior sound protection solution compared to other products available on the market. The Sylomer® bearing elastically decouples flights of stairs from the rest of the building, which in turn reduces the transmission of vibrations responsible for causing noise. The sound control measure is suitable for all standard concrete staircases in residential, commercial and industrial buildings as well as for in-situ concrete and precast concrete stairs. “Sylomer® has proven its worth as a bearing for stairs for more than 30 years. The new SB10 bearing is a logical development of this technology and can withstand conventional stair flight loads over a six-metre span. The maximum permitted design load of this bearing (Vd) is 75 kN/m. Sound control is thus guaranteed across the entire load range,” explains Sebastian Wiederin, the responsible project manager at Getzner.
