Schöck are the UK suppliers of:

Isokorb® Thermal Break for Balconies

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.

Schöck Tronsole® for impact sound insulation 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.

Thermoanker® Thermal Anchor for Precast walls

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.

Novomur® Ground Floor Thermal Bridging solution

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.

Dorn® Shear Reinforcement & heavy duty dowels

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.

Bole® Punching Shear Reinforcement

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.

Combar® Glass Fibre Reinforcement

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 Bole prevents punching shear problems at Tottenham Hale Tower

March 2020

Flat slab construction carries with it the inevitable risk of punching failure. When loads in the stress areas are increased, careful thought has to be given to criteria such as the quality of the concrete, additional reinforcement content, even enlarging the column heads. These options are neither time efficient nor cost effective, and rarely solve the problem to an acceptable performance level. In addressing any potential problems of punching shear at the major new Anthology Hale Works tower, the solution needed to be cost-effective, easy-to-install and certainly dependable.

At the heart of Tottenham Hale, one of North London’s most diverse communities, Hale Village is a multi-award winning urban development. It already includes a mixture of private and affordable homes, student accommodation and a range of non-residential uses including a gym, supermarket, community centre and church. Hale Village has been voted one of the top 30 best regeneration projects in the UK and the most Innovative Affordable Housing Scheme. The last piece of land currently being developed is Anthology Hale Works Tower. This elegant 108 metre high, 32 storey tower offers 279 homes and over 12,000 sq ft of mixed commercial use. There is a selection of studios, one and two-bedroom homes with other features including a 24-hour concierge, resident’s sky lounge and garden, expansive landscaping and private balconies. The striking design of the tower will act as a landmark for Tottenham Hale and Hale Village, whilst simultaneously achieving the highest design and environmental standards.

The prevention of punching failure is critical though
With flat slab construction and the increasing trend for thinner slabs, there is the inevitable risk of punching failure around column heads. So when loads in the stress areas are increased, consideration has to be given to issues such as the quality of the concrete, additional reinforcement content, even enlarging the column heads. These options are neither time efficient, or cost effective and rarely solve the problem to an acceptable performance level. Construction at Anthology Hale involves a single-storey basement box, partly situated above a live London Underground tunnel and bordered on one side by Tottenham Hale station, and existing buildings to the other three sides. The 32 storey building has a jump-formed core and concrete frame, with the first six levels being acoustically separated from the basement structure, due to the adjacent London Underground line. First and foremost flat slab floor is an economical form of construction, but it offers other benefits as well. The minimisation of shuttering time for example, simplification of reinforcement work, ease of underslab work such as ducting and just as importantly, the optimum use of space. However, with flat slab construction the risk of punching failure is always a critical issue. When increasing the loads in the stress areas, a great deal of consideration has to be given to variables such as the quality of the concrete itself, improving the reinforcement content and even enlarging the column heads. None of these options is necessarily time efficient or cost effective. They rarely solve the problem to an acceptable performance level either. So the ideal solution to resolving any potential problems of punching shear needs to be cost-effective, easy-to-install and certainly dependable.

Increased shear force resistance of around 70%
The reinforcement system used to prevent punching failure at Anthology Hale Works is the widely used Schöck Bole system. This reliable and trusted solution consists of double-headed studs and anchors, with spacing bars, which enable installation after the bottom reinforcement and before the top layer. Two spacer bars are welded to the vertical studs, which ensure the correct distance between uprights; and the forged stud heads guarantee a perfect finishing bond with the concrete. When compared with a typical stirrup reinforcement system, an increased shear force resistance of around 70% is achievable. It is a genuinely cost-effective and timesaving solution.

Other variants – plus Schöck design software too
In addition to the standard Bole solution, Schöck has developed three other punching shear reinforcement variants. The type U is a solution designed for installation before the lower mat; the type O is for installation after the top reinforcement layer; and the type F is designed for use in element slabs at prefabricating plants. The entire range is supplied ready for installation and provides a totally reliable solution to the problem of punching shear in flat slabs. There is downloadable user-friendly Schöck design software available too, which enables fast and simple dimensioning of the product to British Standards and the export of CAD drawings with dxf-format.

Latest Wembley success for the Schöck Isokob

January 2020

The 85 acre redevelopment of Wembley Park, in North West London, one of Europe’s largest regeneration projects continues apace. And one of the latest buildings to be completed is The Alameda (Spanish for ‘walkway shaded by trees‘), which sits next to the tree-lined Wembley Park Boulevard. The Alameda comprises two blocks, 10-storey and 15-storey, which provide 340 new residential apartments with cafes and restaurants planned for the ground level. The slide-on balconies, both at the front and rear of the buildings, are a striking feature of the new development – but critical to their structural and long–term insulation performance is the incorporation of Isokorb structural break units from Schöck. The type used in the detailing on the Alameda is a load bearing thermal element with 80 mm insulation thickness. Early involvement was necessary to ensure that the connectors were accurately cast into the building during the mainframe construction phase. A stub bracket was attached to the Isokorb units and the balcony cantilever support arm was then attached (same depth as the balcony) to the stub and the fully pre-assembled balcony chassis slid on to the cantilever arm and locked into position.

Thermal bridging is a critical issue
If there is ineffective insulation at the connection points, especially with so many balconies involved, there will be local heat loss, resulting in more energy being required to maintain the internal temperature of the building. This is a major consequence of thermal bridging, but there are other issues too. Low internal surface temperatures in the area of the thermal bridge can cause condensation, which leads not only to structural integrity problems with absorbent materials such as insulation products or plasterboard, but It also encourages mould growth, which can have serious health implications for residents, particularly older people and children, in the form of asthma and allergies. So for any project involving balcony connectivity the prevention of thermal bridging is a critical issue.

Construction dependability and freedom of design
As the leading international supplier of structural thermal breaks, Schöck has almost limitless variants available in its main Isokorb range, offering planners complete construction dependability and enormous freedom of design. The comprehensive Schöck Isokorb range offers solutions for concrete-to-concrete, concrete-to-steel, steel-to-steel, a thermally insulating connection for reinforced concrete walls – and even a maintenance free alternative to wrapped parapets. All products meet full compliance with the relevant UK building regulations; have NHBC approval; offer LABC Registration and independent BBA Certification. The temperature factor used to indicate condensation risk (fRSI) which must be greater than, or equal to, 0.75 for residential buildings, is also easily met by incorporating the Isokorb.
