London’s Riverwalk incorporates Passivhaus standard Schöck Isokorb

On the north side of the Thames in central London, the three riverside embankments, Chelsea, Victoria and Albert, are the result of extensive civil engineering works that reclaimed marshy land, narrowed the width of the river and provided a large-scale new area of development during the late 19th century.    Today almost 150 years later, much of the area is once again being transformed as the result of a scheme designed to replace many of the outdated buildings which have characterised these areas for so long. There will be high specification property construction, promenades and parks; and at Millbank, one of the major residential riverfront developments is Riverwalk.

Passivhaus standard Schöck Isokorb

Riverwalk features two organically shaped buildings of seven and seventeen storeys, connected by a central podium and incorporating 116 high specification one, two, three and four bedroom apartments, plus penthouses. The design focus is on light, space, service and exceptional views across the Thames.   Aesthetically the buildings are enhanced by horizontal bands of limestone on the curving facades between the glazing and ceramic panels, with the stonework wrapping around the lower parts of the balconies to create a continuous organic shape.

The avoidance of thermal bridging is critical

With such a high specification development, early consideration was given to the avoidance of the thermal bridging at the critical balcony connections. Thermal bridges would result in higher heat transfer through the assembly and colder surface temperatures on the warm side of the assembly.

Some of the consequences of this being higher energy use for heating and cooling, non-compliance with UK Building Regulations, potential building structure corrosion and the risk of mould growth and associated health concerns from respiratory problems. To help minimise any risk of thermal bridging, the structural thermal break module specified throughout the Riverwalk development is the latest generation Schöck Isokorb for concrete-to-concrete applications, the type KXT.

Isokorb type KXT

This latest example of Schöck engineering means even better performance, which is critical in meeting the inceasingly stringent EU guidelines and the imminent need for nearly zero-energy building standards. The Schöck Isokorb type KXT pushes the technical boundaries in meeting these demands.

In addition, through close collaboration with its clients, Schöck has also now optimised the load capacity of the Isokorb range. As a result, the load capacities most frequently in demand have been identified and appropriate refinements applied to the product portfolio.   The range now provides planners with not only a structurally optimised product solution for the construction of cantilevered components, but cost advantages as well.

Verifiable performance values

The product offers such a high level of insulation, that in Germany the Passivhaus Institute in Darmstadt has awarded the product with the low ‘thermal bridge construction‘ certificate and confirmed its suitability even for Passivhaus construction. The product has also just been awarded the very latest BBA certification.   All units meet full compliance with the relevant UK building regulations, which require that the temperature factor used to indicate condensation risk (fRSI) must be greater than or equal to 0.75 for residential buildings. The range also provides Local Authority Building Control Registration and there is compliance too with the UK government Standard Assessment Procedure (SAP 2012) concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges.

Here, the lambda values of the Schöck Isokorb enable energy loss in various connective situations to be reduced by as much as 84% to 91%.

Canaletto tower balconies incorporate Schöck Isokorb


The Canaletto residential tower at 257 City Road in London is located halfway between Old Street and Angel Stations in Islington, alongside the regenerated City Road Basin.  It comprises a 31-storey tower with 190 luxury one, two and three bedroom apartments built to the standards of Code 4 Sustainable Homes Level 4.   Among the many residential benefits of Canaletto living is a cinema, restaurant, entertainment centre and a sky terrace on the 24th floor.

The tower is concrete frame and has a curving facade of metal and glass that breaks the volume into a series of three-to-four storey clusters.  In turn, each cluster contains grouped balcony terraces, which are a striking feature of the building.  The balconies are of steel construction connected to the concrete frame and as always with cantilever construction elements of this nature, one of the early design considerations had to be the prevention of thermal bridging.

Thermal bridge heat losses are in fact responsible for an increasing percentage of the overall building heat loss, due to airtightness and fabric U-values having been improved in UK Building Regulations. Thermal modelling calculations show that for multi-residential projects such as large apartment blocks, thermal bridges could account for 20%-30% of thermal losses, with balcony connections being a major contributor if effective thermal isolation is not included in the design(1).

One of the most effective methods of combatting thermal bridging is the Isokorb range of thermal break elements from Schöck; and for the high specification Canaletto project the Isokorb type KS20 offers the ideal solution. It is a concrete-to-steel connectivity module that sits between the outer and inner structural connection points and blocks the outflow of heat through the use of high quality polystyrene insulation foam.  There are tension and shear stainless steel bars passing through it, which take the tension and shear forces between the building frame and the balconies, enabling a thermally insulated, load bearing connection to be made between reinforced concrete and steel construction components.  The type KS provides a clean and unobtrusive connection detail, minimises on-site assembly time and enables a high level of prefabrication.


The Isokorb range provides a huge selection of solutions for concrete-to-concrete and steel-to-steel, as well as concrete-to-steel – and the entire range offers the security of BBA Certification and LABC Registration. It also comfortably exceeds the requirements of BRE IP1/06 and Part L of the Building Regulations where the temperature factor used to indicate condensation and mould growth risk (fRSI) must be greater than, or equal to, 0.75 for residential buildings.

In addition, there is also compliance with the Government Standard Assessment Procedure, SAP 2012, concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges.  Here, the lambda values of the Schöck Isokorb enable energy loss in various connective situations to be reduced by as much as 84% to 91%.

Schöck and Hollowcore innovation benefits Stoke Extra Care scheme


A PFI Extra Care complex at Abbey Hulton village, outside Stoke-on-Trent, is another UK project benefitting from a faster build time using innovative off-site manufacturing. It combines Isokorb structural thermal break units from Schöck with the Hollowcore system.

Holdcroft Fields at Abbey Hulton, provides 175 self-contained one and two bedroomed apartments with extensive communal facilities for people over 55.

Designed to meet BREEAM Excellent standards, there are two linked three-storey blocks around two central courtyards and many of the apartments feature spacious balconies. So the prevention of thermal bridging is a critical consideration.

Quite apart from heat loss, condensation can lead to structural integrity problems and may even encourage mould growth, which has serious medical implications. One of the most effective countermeasures on the market is the Schöck Isokorb structural thermal break.

It dramatically reduces thermal energy loss in connective areas and enables inner surface area temperatures to remain well in excess of those likely to cause condensation.

To meet the steel cantilever requirements on the project, the Isokorb type KS14, for concrete-to-steel connectivity is being installed in conjunction with the Hollowcore floor system. The method involves the precasters breaking out selected cores and cast reinforcement bars in their works.

The thermal breaks are then fixed to a template, to match the broken out Hollowcore,. complete modules are supplied to site, dropped into position and the broken out Hollowcore filled with insitu concrete.

The Hollowcore has voids extending its full length, with a huge weight saving over floor slabs of equal thickness or strength, and efficiencies in transportation and material costs. With slab sizes on the project typically 1.2m wide by 7.5m long, they are also faster to install and provide an immediate working platform for following trades.

Hollowcore  - HR

The Isokorb type KS14 has verifiable performance values, providing BBA Certification and LABC Registration, as well as comfortably exceeding the requirements of BRE IP1/06 and Part L of the Building Regulations.

The temperature factor used to indicate condensation risk (fRSI), must be greater than, or equal to, 0.75 for residential buildings and this is comfortably met by incorporating the Isokorb.

If the surface temperature factor (fRSi) is controlled incorrectly, thermal bridging is likely to result in condensation and mould growth problems.

.   Chris Willett, MD at Schöck Ltd, considers the issues involved

To identify areas where there is a risk of condensation and therefore mould growth in different design situations, a ‘surface temperature factor’ (fRsi) can be used. It allows surveys under any thermal conditions and compares the temperature drop across the building fabric, with the total temperature drop between the inside and outside air. The ratio is described in BRE IP1/06; a document cited in Building Regulations Approved Documents Part L1 and L2 and Section 6 in Scotland

It is a critical calculation, as the consequences of condensation and mould growth are likely to be more serious for building occupiers than any local heat loss. If low internal surface temperatures in the area of a thermal bridge are below the dew point of the air, condensation is almost certain to form.   This in turn is likely to result in structural integrity problems with absorbent materials such as insulation products or plasterboard – and of even greater concern, the occurrence of mould growth. Practically every building contains mould spores within its fabric which are dormant and completely harmless. However, given the right conditions these spores will germinate and become a potential health risk to occupants in the form of asthma and allergies.

Example of mould growth 1 - HR

Mould is not a new phenomenon of course, but a combination of circumstances is elevating interest in the problem. Primarily these are better insulated and more airtight buildings, improved energy efficiency requirements and much greater environmental awareness. Mould starts to form when the relative air humidity reaches 80%, and often before there is evidence of any condensation.

As the actual surface temperature will depend greatly on the temperatures both inside and out at the time of the survey, the surface temperature factor (fRsi) has crucially been formulated to work independently of the absolute conditions.FRSI - MOULD GROWTH - HR

Using the formula, the recommended (fRsi) value for offices and retail premises is equal to or greater than 0.5; and to ensure higher standards of comfort for occupants in residential buildings, equal to or greater than 0.75. In more extreme conditions of high humidity, such as swimming pools or other wet areas, 0.9 would be anticipated.   In summary, the surface temperature factor required will depend on the use of the building and the consequent internal relative humidity. To eliminate the possibility of condensation and any resultant mould growth, the higher the likely internal humidity, the greater the need for a higher surface temperature factor.


Schöck prevents thermal bridging in major new Irish distillery


Marketing and distribution across Ireland of the major Pernod Ricard premium wine and spirit brands, such as Malibu; Jacob’s Creek; Brancott Estate and Mumm; is big business for Irish Distillers Pernod Ricard.  However, the company’s real heritage is in its whiskey brands, particularly Jameson Irish Whiskey, which is produced at the main distillery in Midleton, County Cork.  The site has a production capacity of 33 million litres of alcohol a year, but even this is still insufficient to meet increasing international demand. As a result, €100 million is being invested in new plant to double the capacity.    When complete, Midleton will be one of the most modern distilleries in the world, boasting three 75,000 litre pot stills, and three column stills, which are used in combinations of three to produce the different types of whiskey.

Sustainability has always played a significant part in Irish Distillers Pernod Ricard’s development programmes and the current expansion is no exception. “Sustainability was a pre-requisite from the outset, from the design stage. Every element was examined from a sustainability perspective”, says Tommy Keane, head of distilling operations at Irish Distillers.   A challenge taken up by the architect John Morehead, of Wain Morehead Architects, who comments: “We were able to incorporate all the tools and techniques we used from doing passivhaus buildings and apply it to this building”.

The 21.5m high pot still hall building envelope is designed to a very high level of thermal performance and one of the design factors that had to be taken into account was the prevention of thermal bridging.  There is of course a regulatory need to reduce local heat loss and CO2 emissions. But in addition, condensation can be a potential problem too, frequently resulting in structural integrity problems – and even mould growth, which brings its own set of health risks to personnel.   The pot still hall has an overhanging roof element and this is insulated to the top, leading edge and underside on the north elevation and part return on the east and west elevations over a glazed wall.   To prevent any risk of thermal bridging at these roof overhang connectivity points, the structural elements to the primary steel are isolated from the interior environment using Isokorb structural thermal break units from Schöck.

The Isokorb is one of the most sophisticated solutions on the market, for the prevention of thermal bridging in connective situations; and has been supplied for the project by Contech Accessories, of Tullow, County Carlow, the Schöck sales partner and sole distributor for Ireland.

The Isokorb offers outstanding thermal efficiency and unrivalled application options, allowing connections to be made between concrete-to-concrete, concrete-to-steel and steel-to-steel. One of the modular connection types even allows the retro-fitting of balconies in certain situations.  At Midleton, it is the KST-QST module for steel-to-steel applications that has been specified.  The KST modules are unique in being able to withstand extremely demanding loads and incorporate stainless steel components to ensure corrosion protection and minimise thermal conductivity.  Due to their thermal insulation properties, the Isokorb modules dramatically reduce energy loss in connective areas by guaranteeing that there is uniformity between cantilever structures and the internal structure at the thermal envelope. They also transfer load and maintain full structural integrity, while at the same time enabling inner surface area temperatures to remain well in excess of those likely to cause mould formation and condensation. The units are easy to fit with regular end-plate connections and all available steel profiles can be bolted on.

The entire Schöck Isokorb range provides BBA Certification and LABC Registration, and comfortably exceeds the requirements of BRE IP1/06 and Part L of the UK and Irish Building Regulations.  These state that the temperature factor used to indicate condensation risk (fRSI), must be greater than, or equal to, 0.50 for commercial buildings, a requirement comfortably exceeded by incorporating the Isokorb into the design.

There is also compliance with the Government Standard Assessment Procedure, SAP 2009, concerning CO2 emissions from buildings, and respectively heat losses through non-repeating thermal bridges. Here, the lambda values of the Schöck Isokorb® enables energy loss through balconies, canopies and other cantilever parts of the building to be reduced by as much as 84% to 91%.

There are hundreds of standard solutions available in the Schöck range and modules can be tailored to suit practically any application, with different types enabling the transmission of shear, bending moment and tension, as well as compression.

A ‘Specifiers Handbook‘ is available which provides an overview and introduction to the Schöck Isokorb®., and there is a thoroughly comprehensive 236 page ‘Technical Guide’ which displays in detail the complete range of thermal break applications for all construction types – concrete-to-concrete, concrete-to-steel, steel-to-steel and concrete-to-timber.

Kemper System showcases complete sustainable roofing solutions

Kemper System’s stand (S1520/21) at this year’s Ecobuild (4-6 March) continues to promote the market leading solvent-free, sustainable and odourless Kemperol 2K-PUR liquid waterproofing system and Stratex Warm Roof System.


Kemper System’s innovative Kemperol 2K-PUR solvent-free and odourless system is the first solvent-free wet-on-wet cold liquid waterproofing system available on the UK market and remains the only product of its kind commercially available.  The past year has seen continued growth in sales for the hard-wearing and durable waterproofing membrane, which bonds to almost any substrate to create a totally seamless, monolithic, U/V stable, elastomeric membrane. Based on an 80% castor-oil formulation derived from sustainable sources, the liquid system also incorporates a flexible non-woven reinforcement fleece, which is manufactured using 25% recycled plastic bottle content.  As the resin saturates the fleece in a single application process, the cured membrane cannot delaminate. Offered with a 20-year warranty, the ground-breaking system is both solvent-free and odourless, making it not only ideal for sustainable new builds but also perfect for upgrades to occupied buildings as the lack of nuisance odours means that work can be carried out while the building remains in normal use. Suitable for application on top of virtually all existing roofing materials, eco-friendly Kemperol 2K-PUR can even help to prevent excessive waste from being sent to landfill during roof upgrades by avoiding the need to strip out the existing failed substrate.

Complementing the sustainability credentials of the Kemperol 2K-PUR system, Kemper System’s Stratex Warm Roof System offers a completely integrated warm roof system that incorporates primers, vapour barrier, insulation and waterproofing with a range of optional surfacing. Featuring a rigid PIR insulation board with a unique tongue and groove interlocking joint, the system significantly reduces cold bridging and gives a much smoother surface finish.


Kemper System will also be showcasing the company’s Kempergro Green Roof System, a three-section system comprising a reservoir attenuation composite, growing medium and vegetation. The reservoir attenuation layer includes an upper filter fleece, central reservoir core and lower protection fleece, which are manufactured from 90% recycled materials and factory bonded to maximise performance and simplify installation. Suitable for use with the Kemperol 2K PUR waterproofing membrane, Kempergro has a growing medium that is 100% composed of recycled brick, tiles and green compost, which is processed and graded to support an extensive range of sedum, meadow and lawn roof media.


Visitors to Kemper System’s stand will be able to see how each of the systems have been used in practice, including how the Kemperol 2K-PUR waterproofing membrane and Stratex Warm Roof System have been used together on various high profile projects. There will also be a number of display areas where visitors to the stand will be able to view samples of the cured product to experience first hand the flexibility and durability it offers.

Oxford Brookes proves ‘common solutions’ for concrete-to-steel connections are inferior to the Schöck Isokorb

Recently there have been misconceptions in some areas of the UK marketplace that certain ‘common solution’ alternatives for concrete-to-steel connections perform just as well as the Schöck Isokorb type KS14 thermal break element.     This is not necessarily the case.   As a specialist in this sector, Schöck demands extremely high product performance standards and has a strong professional interest in ensuring that alternative solutions comply with the necessary building regulations – and that any performance claims are verifiable.

To bring clarity to the situation, an independent investigation into the various performance criteria concerning the effectiveness of steel balcony connections to concrete slabs has been carried out by the Oxford Institute for Sustainable Development, at Oxford Brookes University.   The ‘common solutions’ in question being the direct connection of balcony support brackets to a concrete floor slab using no form of thermal break; a solution using brackets in conjunction with a 10mm ‘thermal pad’; and a further connection solution using a thicker 20mm ‘thermal pad’ .

The OISD found the Isokorb type KS14 to be a superior thermal insulating element for connecting cantilevered steel components to reinforced concrete; while other comparable solutions failed to obtain the minimum amount of performance required by Part L of the Building regulations.

The first step in the independent investigation process was to determine the heat loss, minimum surface temperature – and consequently the temperature factor (fRSI) – resulting from the use of Schöck Isokorb type KS14 thermal break units connecting a steel balcony to a concrete floor slab.    The temperature factor (fRSi) is used in the UK to indicate condensation risk as described in BRE IP1/06, a document cited in Building Regulations Approved Documents Part L1 and L2.

Once established, this calculated performance (1) was then compared with that of the three structurally equivalent ‘common solutions’.   The following results table presents the minimum surface temperatures and temperature factor (2) for the cases modelled, where the temperature factor used to indicate condensation risk (fRSI) must be greater than or equal to 0.75 for residential buildings.

It is quite clear that the Isokorb KS14 unit, with fRSi = 0.904, exceeds these values by some margin and will therefore meet the requirements of Building Regulations Approved Documents L1 and L2.    Further, the results demonstrate that where no unit is used (fRSI =0.681) and also with the 10mm and 20mm pad connections (fRSI =0.713 and 0.706 respectively) – all three would fail against the criteria required for residential buildings.

Temp Distribution - KS14 - HR

The temperature results concluded:

Description                         Min.surface temp °C     Temp factor fRSi
No balcony connection                                                                   0.949
Model 1 – Direct connection              13.62                                    0.681
Model 2 – Pad connection 10mm      14.26                                    0.713
Model 3 – Pad connection 20mm      14.11                                    0.706

Specifiers, contractors, developers and those in procurement therefore need to be wary of product performance claims involving bespoke solutions.   Often they will be found wanting and the lack of transparency in determining true performance values may well mean a product being installed that is simply not fit for purpose.  Due to building site ‘tolerances’ it is vital that thermal product solutions should, at the very least, exceed minimum standards – and even that may simply not be good enough.

Schöck is a leading supplier of innovative thermal product solutions to the international construction industry and maintains its position by investing heavily in wide ranging technical research and product development activities.   This is particularly true of its Isokorb thermal break range, which has an unrivalled reputation for its ability to prevent thermal bridging in cantilever connectivity areas and increase the thermal performance of buildings.

Creative solutions from Schöck at new University Design Centre

The new £14.7m East Park Design Centre at Loughborough University is a striking addition to the campus and the first project in a wider master plan for the modernisation of the mainly 1960’s East Park area.


Designed by Burwell Deakins Architects, the 7,500m2 development is rated BREEAM excellent and offers a wide range of facilities including teaching and lecture spaces, research laboratories, workshops, computer suites, offices and a café.

A highly distinctive feature of the building is the saw-tooth design on the south façade and the extensive use of zinc cladding and sheer glass surfaces on the external envelope.  On the south and west elevations there are external solar fins (or shades) to protect against excessive glare and heat gain; and the curtain walling specification incorporates opaque insulated glazed units which minimise excessive heat loss in winter.  Internal ducts enable the deep plan workshops to be naturally ventilated, reducing the requirement for mechanical ventilation.


A critical consideration in the design is the prevention of thermal bridging and its consequences.   Quite apart from the regulatory need for a major reduction in local heat loss and CO2 emissions, there are other factors too.  If low internal temperatures around the thermal bridge are below the dew point of the air, condensation will form.  This in turn can lead to structural integrity problems with absorbent materials.  Worse still, it encourages mould growth, which has serious implications for building occupants and may cause them to develop certain medical conditions such as respiratory problems and dermatitis.   

The most sophisticated solution for the prevention of thermal bridging, in connective  situations, is the market leading Isokorb® range of thermal break modules from Schöck.  Quite apart from its unique design characteristics and outstanding thermal efficiency, it is a range with unrivalled application options.   The Isokorb® allows connections to be made between concrete-to-concrete, concrete-to-steel and steel-to-steel; with one of the modular connection types even allowing the retro-fitting of balconies in certain situations. 

The East Park Design Centre is a concrete frame construction, and three variants of the Isokorb® range for connecting reinforced concrete-to-reinforced concrete have been incorporated.  The Isokorb® type Q30 has been installed to serve as a shear force transfer element where ‘cold’ external staircases or landings connect to an internal ‘warm’ structure in the building.  The Isokorb® Q30 also has F90 fire protection.    .Additional stability for the walls is required in certain areas of the new Design Centre and this is achieved through the incorporation of standard HPC load bearing thermal insulation units, which are connected to the slab.   Bespoke Isokorb® units complete the picture, designed to separate corbels attached to the internal slab.

These three different solutions demonstrate that although the Isokorb® range is best known for its effectiveness at balcony and walkway connections, it performs equally well when other structural design features demand thermal separation.

The Isokorb® range comfortably exceeds the requirements of the UK regulation (BRE IP1/06) which stipulates that the temperature factor used to indicate condensation risk (fRSI), must be greater than, or equal to, 0.75 for dwellings, residential buildings and public buildings.


Also, there is compliance with the Government Standard Assessment Procedure, SAP 2009, concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges.  Here, the lambda values of the Schöck Isokorb® enable energy loss in various connective situations to be reduced by as much as 84% to 91%.   All products provide BBA Certification and LABC Registration.

The proven high technical performance values of the Isokorb® range have been the main driver in helping establish and maintain the current market position for Schöck in the UK.  However, developing its support services plays no small part either. Significant attention is being given to providing specifiers, structural engineers and contractors with a high level of design and technical input.  The growing Schöck Technical Team, based in Oxfordshire, is becoming increasingly project orientated and working more closely with clients on day-to-day job related issues.


Further support is available in the form of a complete library of information available as hard copy, or downloadable information from the website.   This includes a 20 page ‘Specifiers Handbook‘, which provides an overview and introduction to the Schöck Isokorb®; and a comprehensive 236 page ‘Technical Guide’ which displays in detail the complete range of thermal break applications for all construction types.
