The StoRend Flex Cote render system was specified for use on the facades of the new Ad Gefrin buildings by Elphick Associates, to provide maximum crack resistance, weatherproofing and fade resistance.

More than 20,000m² of Sto’s external wall insulation system has been specified for two residential schemes at Cherrywood, Ireland’s largest urban development driven forward by real estate group Hines and its joint venture partners, APG Asset Management over the past seven years.Located on a 360-hectare site to the south of Dublin, Cherrywood is expected to serve a population of 25,000 people, offering more than 7,700 new homes, six schools, three parks and leisure facilities.Henry J Lyons Architects selected the StoTherm Mineral insulation system for apartment blocks forming part of the first and second phase of the residential construction. Now complete, the first scheme comprises 431 homes divided into two equally-sized blocks. The second consists of 520 units spread across three blocks and is due to be completed in Summer 2023. Sto installation work was carried out by applicators Platt Reilly.Consisting of mineral fibre insulation boards, the StoTherm Mineral system provides a high level of thermal performance and fire protection. It has been installed onto lightweight steel frames using Sto-Rotofix Plus. Thanks to a unique spiral design, these fixings help to create a seamless façade across all the blocks as well as a cavity behind the insulation board allowing any excess moisture to drain. Using the Sto-Rotofix-Plus, any unevenness in the substrate can be easily rectified by adjusting the insulation boards after they have been installed. This means there is no need for unsightly expansion joints and a smooth surface can be created ready for applying the render.All the apartment blocks will be finished with the StoSilco silicone resin render to provide high levels of water repellence and resistance to algae and fungus growth. 

Located in Tower Hamlets, Gayton House and Sleaford House are managed by housing association Poplar HARCA. Following amendments to Building Regulations, which banned the use of combustible materials in external walls of high-rise buildings above 18m, StoTherm Mineral K was specified to replace the existing EWI system.BBA-certified, StoTherm Mineral K comprises mineral fibre insulation boards and the system is classified with an A2-s1, d0 reaction to fire in accordance with BS EN 13501-1.Working on behalf of Westminster Building Company, Square 1 Architectural Solutions was responsible for removing the existing EWI and installing the StoTherm Mineral K system onto four elevations on each 23-storey block. The non-combustible mineral fibre insulation boards were secured to the existing concrete substrate using adhesive and mechanical fixings, and without the need for additional expansion joints.A StoLevell Duo Plus reinforcing coat embedded with Sto-Glass Fibre Mesh was then applied to the face of the insulation boards. This was followed by the application of 1.5mm stippled StoSilco, a silicone resin render that provides high levels of water repellence to protect the walls from weathering.

The StoTherm Classic M external wall insulation system was specified for the new Day Hospice building at Mary Stevens Hospice in Stourbridge.

An historic landmark in the Lake District has been given a new lease of life with the installation of StoTherm Mineral K external wall insulation and StoSilco finishing render. Built in 1937, the building in Keswick originally housed the UK’s first pencil factory, and now provides new headquarters and site for the Keswick Convention for the Keswick Ministries organization. After being used by the Cumberland Pencil Company the building had fallen into disrepair. Set at the entrance to Keswick, this important local landmark has now embarked on a £10.5m redevelopment project, split into four phases. The Sto materials have been used on the first phase which has seen the building’s front elevation fully restored, and they have also been specified for the remaining three stages of the work.The BBA-certified StoTherm Mineral K system combines impressive insulation with unrivalled fire protection characteristics. It features Sto-Mineral Fibre thermal insulation boards, which in this case were fixed to the substrate using StoLevell Duo Plus mineral bonding and reinforcing mortar.  “This allows any unevenness in the surface of the substrate to be accommodated and makes installation a fast and easy process,” comments Alan Rees of Eco Rend North East who installed the Sto system. This efficient single-leaf construction allows for excellent thermal performance without reducing the interior space, and as it requires no additional expansion joints, a smooth and unbroken exterior surface can be created.  An additional mineralic reinforcing coat was applied and the exterior surface was finished with StoSilco silicone resin render.  With high CO2 and water-vapour permeability, StoSilco render allows a weather- and water-repellant outer surface to be created in any of the 1,000+ colours available in the StoColor System.  

The StoVentec Glass rainscreen system featured on the upper part of this 84,000 sq ft Marks & Spencer store in Maidstone was specified by architects Corstorphine & Wright for this £25 million project. 900m2 of StoVentec Glass panels were manufactured on a completely bespoke basis and finished in a pre-specified RAL colour to complement the modern design of the building and the other construction materials that were used. The StoVentec Glass system was designed and installed by specialist contractor Southern Maze Ltd, using Sto’s innovative sub-construction that can be mounted onto virtually all substrates, with no visible frames, rails or fixings. The store is regarded as a flagship out-of-town project for Marks & Spencer and features a bakery and food hall alongside other retail spaces. 

A new Scottish residential development with a strong emphasis on offsite construction and energy-efficiency has highlighted the suitability of Sto’s external render systems for use with modern structural insulated panels (SIPS).

Some 675m2of white StoVentec Glass were installed in a three-story communal area inside the building. This reflects the natural light entering via the roof skylights to create an airy and open environment, while also contrasting visually with the exposed brickwork

One of the tallest new buildings recently added to the Bournemouth skyline has been completed with a combination of external wall insulation and render products supplied by Sto. The company’s StoTherm Mineral M system, with Sto-Rotofix Plus mechanical fixings and StoSilco exterior render were all used on the new Skyline student accommodation building, which achieved a BREEAM ’Very Good’ rating.

Sto’s specialist façade solutions have ensured a new affordable housing development seamlessly integrates with its surroundings. Located in West Kensington on the Springvale Estate, ‘Tavener Court’ comprises eight one and two-bedroom flats as well as two three-bedroom houses, spread across three floors.Externally, the scheme features the StoTherm Mineral external wall insulation system, which has been finished with StoSilco silicone render in a pale shade of yellow, and a variety of StoDeco three-dimensional profiles to add architectural detailing across the building. With 1,000 colours to choose from in the StoColor system, the Sto render offered extensive design flexibility for architecture and design company, NORR. It has also provided a high level of water repellence and water vapour permeability, making the façade resistant to the build-up of dirt and reducing the growth of algae and fungus. The StoDeco profiles were specified to create window surrounds in pure white, corner detailing around the roof area, and a decorative band course across the façade. Manufactured from Verolith, which comprises 90 per cent perlite, the StoDeco profiles are highly resistant to weather and other environmental factors. Light in weight and easy to work with on site, the products are quick to install and form a durable bond with the render. 

Two new apartment buildings in Kent have been given a thermally-efficient and visually-striking façade thanks to the use of an external wall insulation system from Sto. The two new blocks in Ashford - Stour Heights and Somerset Heights – have a single-skin construction, comprising a reinforced concrete frame with concrete block infill, and they benefit from the installation of StoTherm Mineral external wall insulation, with a StoCleyer B mineral brick slip and StoSilco render façade finish.“An alternative insulation system was originally proposed for these buildings,” says John Mahoney of Sheffield-based J Mahoney Architects. “As things progressed a different solution was required to meet the demands of the various parties involved in the project. Sto pretty much leads the pack in terms of quality, and the StoTherm Mineral system was able to satisfy everyone’s requirements, so it became the obvious choice. The fact that Sto could work with us and provide technical support was also extremely helpful.”The BBA-certified StoTherm Mineral external wall insulation system uses mineral-fibre boards to provide outstanding thermal performance, combined with reliable fire protection and effective sound insulation. Its efficient single-leaf construction and external installation do not compromise the building’s interior space, and it can be installed without the need for additional expansion joints.For the new buildings, it was installed using Sto’s unique Sto-Rotofix plus mechanical fixing system. The helical Rotofix fixings create a cavity behind the insulation board, which can be easily adjusted after installation to ensure a level outer surface is created. This system combines the ease-of-use of ETICS anchors with the flexibility of a mechanical rail system, but without the material and labour cost of installing the rails.“The StoCleyer B brick slips were specified to meet certain planning requirements,” adds John Mahoney. “An alternative brick solution was originally considered, but Sto was able to manufacture slips which were a perfect match for the proposed original. The fact that they were also fully compatible with the Sto insulation system was another significant point in their favour.”The new buildings have added 109 one- and two-bedroomed flats which are spread across the five floors of Stour Heights, and the three floors of Somerset Heights.

A new energy centre in the heart of west London has been given a dramatic and eye-catching appearance thanks to the use of a portfolio of façade products provided by Sto.

Sto has supplied the StoTherm Mineral K external wall insulation system with StoLotusan render for the new Day Case and Eye Unit building at Chorley and South Ribble Hospital. Specified by Gilling Dod architects of Chorley, who worked closely with the main contractor Tilbury Douglas, the StoTherm Mineral K system combines impressive insulation with excellent fire protection characteristics. With an A2-s1, d0 reaction to fire classification in accordance with BS EN 13501-1, the non-combustible mineral fibre insulation is fully bonded to the substrate and therefore no additional firebreaks are required. Ideal for both new-build and refurbishment projects, its efficient single-leaf construction also means that interior space within the building is not reduced.  For this project, the system’s mineral fibre insulation boards were secured to the lightweight steel frame and sheathing board substrate with mechanical fixings and StoLevell Uni adhesive and levelling mortar. A StoLevell Duo Plus reinforcing coat embedded with Sto-Glass Fibre Mesh was then applied to the face of the insulation boards, with StoLotusan and StoSilco renders used for the final finish on different sections of the building, using light colours from Sto’s architectural colour range.  StoLotusan is the only render available that uses Sto’s patented Lotus-Effect® technology which delivers impressive water and dirt repellence. It forms a unique surface texture, similar to that of the lotus leaf, that causes the rainwater to run off the render quickly and easily, removing any dirt or dust as it goes. Providing outstanding resistance to the growth of algae and fungus, the building will retain its looks for many years to come.  The new Day Case and Eye Unit is the result of a major £17.5 million investment in developing enhanced ophthalmology and day case services. The new Day Case and Eye Unit now offers an extensive range of diagnostic and treatment facilities for patients with medical eye conditions.

Working closely together, Sto and MICAM design and manufacture wall lining and facade cladding solutions to meet the demands of today's public space built environments.When designing and constructing new transportation hubs, leisure complexes, shopping malls, entertainment venues and other public spaces, it is vital to do all we can to protect the lives of the people who use them.Today's advances in technology and engineering have led to the development and validation of structural glass and cladding systems that can ultimately mitigate the risk from the impact of blasts, as well as offering many other benefits

A combination of external wall insulation and resin brick slips from Sto has helped create a thermally-efficient and visually striking appearance for a £7.8m residential refurbishment project in London. Located on the Stockwell Park estate, Tyler House now benefits from the use of Sto resin brick slips which have been installed as the final façade finish, onto the company’s StoTherm Mineral K external wall insulation system. The Tyler House building is organised around a central courtyard, and houses 48 flats with one, two, three or four bedrooms. “The buildings underwent a significant amount of refurbishment in order to improve the living conditions of the residents, and providing effective thermal insulation was a key element in that process,” explains Richard Watson of project architects Rock Townsend. “The Sto solution allowed us to provide that insulation. We also wanted to add 13 additional flats and the Sto brick slips gave us the opportunity to create a dramatic new appearance for the existing parts of the building which would contrast with the rooftop extension.” The Sto materials were installed by Sto applicator Regency Plastering of Dartford. “The residents remained in their homes throughout, and there were no problems in installing the external insulation and brick slips whilst they were there,” explains Regency’s Paul Brown. The BBA-certified StoTherm Mineral K insulation system is ideal for refurbishment projects such as Tyler House. Its external installation means that insulation performance can be substantially upgraded without the loss of any living space inside the premises. Comprising mineral-fibre boards which deliver high thermal performance and unrivalled fire protection, the system also incorporates reinforcing layers to provide additional impact resistance. For this project the insulation was installed using StoLevell Uni adhesive and supplementary fixings to create a strong and reliable bond with the substrate. Designed specifically for use with Sto’s external wall insulation systems and StoRend systems, the Sto mineral brick slips used on Tyler House are manufactured from a rugged and durable synthetic render, and combine a realistic simulated brick appearance with reliable, weatherproof properties. They can be used to match the appearance of surrounding buildings without compromising on thermal insulation, or as in this case, to create dramatic and individual facades. For Tyler House they were specified in a white brick slip colour which contrasts with the new, rooftop extension.
