Schöck are the UK suppliers of:
Schöck Isokorb® is the heat-insulating load-bearing thermal break for cantilever balconies. The Isokorb® prevents thermal bridging and is used for connecting reinforced concrete to reinforced concrete, reinforced concrete to steel and steel to steel balcony decks. Isokerb can be used on both new build and for upgrading of existing balconies and even offers an effective alternative to wrapped parapets.
Staircase noise is detrimental to the quality of living conditions and can reduce the value of a building. For high construction quality it is recommended to include top-quality impact sound insulation in sustainability planning. Schöck Tronsole® is an efficient solution. The perfectly matching system of impact soundproofing elements combines dependable sound insulation with simple installation. The Schöck Tronsole® variants are perfectly matched to each other and ensure efficient impact sound insulation that encompasses all structural element subsections on both straight and winding staircases.
The Schöck Thermoanker® is the energy-efficient alternative to conventional stainless steel lattice girders when connecting the concrete skins of core-insulated sandwich and element walls. Compact and easy to install, it also improves cost efficiency when prefabricating concrete parts. The Schöck Thermoanker® can be used in conjunction with any type of insulating material, thus offering prefabricating plants and architects a construction material for thermal breaks in façades that is fit for the future.
The point between the basement slab and outer walls is a danger area where thermal bridges and damp can easily form. Novomur® is an insulated block that prevents thermal bridging and damp penetrating buildings at ground level. It serves as the first course at the point where the basement ceiling forms the ground floor outer and inner walls. Novomur® thermal block is built into the first course of brick or blockwork and is available in all regular wall thicknesses: 100 mm, 115 mm, 150 mm, 175 mm, 200 mm and 240 mm and comes in 750 mm standard lengths.
Whether you are installing concrete slabs in high-rise buildings or supporting walls in underground garages: Distributing the shear forces in dilation joints usually requires additional time and effort. Schöck Dorn® are quite the opposite. The shear reinforcement and heavy-duty dowels for transferring shear forces in expansion joints are ready for installation and dispense with the need for complex detailed solutions. This shear reinforcement is affordable, reliable and intelligent.
The Schöck Bole® is an anti-punching shear system that offers specifiers the advantages of a free floor area. Non-load bearing partition walls are possible, lower noise and reinforcement expenditure, Bole allows room to work freely right up to the ceiling and full use of storey height.
For decades, steel has been the material of choice for reinforcement in concrete construction. But in particularly corrosive surroundings or construction that must be executed without steel, conventional steel rebar does not satisfy the relevant requirements. This is where Schöck Combar® glass fibre reinforcement offers all sorts of options.
Schöck customer support offers a totally comprehensive information service which includes: software, planning, in-house training, seminars and comprehensive technical specification details.

Schöck product solution is just dandy at Regency Heights
The Old Oak and Park Royal areas of West London are undergoing a massive transformation. A £26 billion masterplan to create a new district is taking shape in this part of London and it will see around 25,000 new homes built over the next 20 years. An already advanced scheme is the First Central development, part of which is the imposing Regency Heights. Built on the former site of the Sir Giles Gilbert Scott designed Guinness Brewery, it is a residential-led, mixed use scheme providing 807 residential units in three courtyard blocks wth a public plaza. The buildings range from five to twenty-seven storeys and the design is reminiscent of the Brewery’s early modern industrial brick architecture. The southern block is anchored by a brick-clad residential tower, which when complete, will create a new 90m high local landmark. The majority of apartments are fitted with steel balconies. So it is vital that with the design detailing any risk of thermal bridging is minimised and a key consideration throughout is the use of effective structural thermal breaks.
Consequences of thermal bridging
Local heat loss is a major factor, resulting in more energy being required to maintain the internal temperature of the building. Also, low internal surface temperatures in the area of the thermal bridge can cause condensation. This can result in structural integrity problems with absorbent materials, such as insulation products or plasterboard. Mould growth is also a possible risk, which in a residential situation can cause asthma and allergies. The proven solution to any such problems is the Schöck Isokorb structural thermal break. In the case of Regency Heights, over 2500 units of the Isokorb T type SK are installed. This is a load-bearing thermal insulation element with an 80mm insulation thickness for connecting cantilevered steel balconies to a reinforced concrete slab. The innovative fastening of the support beams makes any steel structure durable, safe and visually attractive, permits a high degree of prefabrication and minimises installation time on site. The T type SK transfers positive or negative moments and shear forces. And since it can bear heavy loads, it is ideal for resolving the technical and structural issues of designing modern balconies.
The Schöck Isokorb T type SK units guarantee totally verifiable performance standards, meet full compliance with all relevant UK building regulations and offer BBA Certification and LABC Registration. When incorporated into residential buildings, the required fRsi value, the temperature factor used to to indicate condensation risk (that must be equal to or greater than 0.75) is always comfortably met. The range complies with the Government Standard Assessment Procedure, SAP 2012, concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges. The lambda values of the Isokorb also enables energy loss to be reduced by as much as 84% to 91%.
Schöck Combar ensures safer tram system and reduced noise
The southern German City of Munich is investing heavily in its public tram sys-tem. Passenger levels are likely to exceed 110m people this year and to help improve operational running, a third-track expansion is underway on the busy section outside the main central station. Traditionally, the track support slabs would be reinforced with steel, however this can create a safety problem with the sensors on modern point-blocking circuits. These function by creating a resonant circuit in the area of the crossover. As a tram approaches, its large steel mass affects the resonant circuit, which is sensed by the track control system. If the carrier plate is reinforced using steel, this disturbs the resonant circuit in a similar way and may lead to interference in the point-blocking circuit – making it difficult for sensors to identify the presence of the tram, putting safety at risk. Any such risk is avoided by using Schöck Combar reinforcing bars, as the glass fibre reinforced polymer product is neither magnetic, nor elec-trically conductive.
Operational safety and vibration reduction too
In addition to the improved safety at crossovers, Combar also offers significant benefits in reducing noise and vibration. Mass-spring systems for these types of track typically consist of a rail carrier plate and a U-Trough shaped foundation of reinforced concrete. The two components being isolated to prevent mechanical vibration. However, because of the risk of local interference with the point-blocking sensors – and the fact that Combar has a tensile strength greater than steel – it was decided to incorporate the product in the mass-spring plates. Combar was installed in the area of the U-Trough and rail carrier plate and elastomer sheeting was used to completely isolate the carrier plate from its surroundings. The elastomer layer also served as lost formwork within the trough and as Combar units have no sharp detailing, there was no risk of them penetrating the layer and causing acoustic bridges.
Historically, steel has been used as the most common reinforcement material in concrete construction. However, the material properties of steel rebar make it unsuitable for many applications and Combar continues to gain ground in more and more markets. The unique physical characteristics of the product are achieved by bundling high-strength glass fibres tightly together, pulling them through a closed chamber and impregnating them with a synthetic resin before cutting. The resultant ribbed reinforcing bar of corrosion resistant glass fibre reinforced polymer is significantly lighter than steel and is neither electrically or thermally conductive.
Combar application examples include easy machinability in tunnel construction, where boring machines cannot drill through steel reinforced shaft walls. With Combar the machine can cut directly through the head wall. High voltage transformers and power plant reactors generate inductive currents within the reinforcing steel. The heat affects the rebar strength if too close to the coils, but Combar remains unaffected. And its corrosion resistance – even from salt – is unrivalled when building bridge and harbour constructions.
