Schöck has developed a new integrated impact sound insulation solution for all structural subsections on both straight and winding staircases.
Known as Tronsole, it is a system that combines dependable sound insulation with straightforward installation. Providing optimum standard-compliant soundproofing in apartment blocks and multi-use buildings.
With conventional solutions, such as an unsecured individual elastomer support under the stairs, any displacement can result in a broken concrete edge due to incorrect support. This in turn means the risk of dirt and gravel getting into the gap between staircase and floor slab, or landing, which can easily reduce acoustic insulation performance by around 10 dB. Schöck Tronsole, by contrast, is a system that envelopes the entire staircase, totally minimising the risk of acoustic bridges.
The system consists of seven main product types that can be mixed and matched to form a fully integrated impact soundproof system either on-site, or in the prefabricating plant. Central to the performance of the Tronsole system is Elodur, an elastomer support formulated to ensure optimum acoustic insulation and low deflection.
Compared with conventional strip supports, Elodur assures an impact sound level difference of approximately 32 dB, which constitutes an improvement of around 10 dB. The Tronsole system is suitable for emergency exits and complies with the requirements for fire resistance class R90 (subject to appropriate on-site additional reinforcement of the landing).
