New staircase impact sound insulation system from Schöck Since its formation in the 1960s Schöck has been developing product solutions that make a substantial contribution to building physics. In the UK the company is best known for its market leading Isokorb structural thermal break range (thermal insulation); but in Europe, insulating stairs and landings against impact sound (acoustic insulation) has been a high priority as well. This is largely due to the historical differences in dwelling types. In the UK only 14% of the population have traditionally lived in apartments, one of the lowest Euro percentages. Whereas the average for apartment living across the Euro area is 48% and in many cases even higher. However things are changing in the UK. Apartment living is dramatically on the rise, resulting in a marked increase in the density of residential living. And in the interests of noise health protection, exisiting mandatory soundproofing standards, of which common stairs and impact sound is an important feature, are coming under ever-increasing scrutiny. The Tronsole soundproofing system As a result, Schöck has developed an 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 conventionsal solutions, such as an unsecured individual elastomer support under the stairs, any displacement can result in a broken concrete edge due to incorrect support. 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). 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. On-site or in the prefabricating plant 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 11 For comprehensive information about the Tronsole system contact Schöck on 01865 290 890; or visit the website at www.schoeck.co.uk The full Product Brochure is available. Also, online installation videos are available that demonstrate the individual steps for installing elements for both straight and winding staircases and landings.
