"ductwork fire dampers and ancillaries"

This work at Holborn’s Chancery House  — The Office Group’s largest location to date spanning 127,000 sq ft — focused on a design that accommodates multiple working zones and breakout spaces, enhances wellbeing and offers an abundance of natural light.Radii’s design department provided multiple bespoke solutions for this fit out, working on four of the building’s nine floors.For glazed fronts, our elegant Parallel 50 (Rw 45 dB) double glazed partitions in emulated satin stainless steel finish — a reference to the historic London Silver Vaults that are located at the base of Chancery House — were utilised along with wraparound framing and a custom blade detail to create an eye-catching visual effect.On the Ground floor, single glazed Linear 59 partitions (Rw 39 dB) with a bespoke pocket sliding door into drywall was installed for platform lift access.Finally, E30 fire rated double doors were placed on the Lower Ground Floor to provide fire route protection.

A residential development, Timber Wharf is located on the corner of the Roman-built Kingsland Road and 19th-century Regents Canal and features commercial space as well as a canal-side restaurant.The residential area is grouped around a quiet cobbled courtyard offering a sheltered play area, while the waterfront apartments make up the courtyard’s northern edge and are set back from the canal, overlooking a very attractive, quaint and safe community garden.We worked very closely with Kier Group PLC (one of the largest regional builders in the UK) and ALU Installations (a leading installer of non-combustible decking and cladding systems in the UK) to deliver this very important remediation project.The timber boards on the walkways and balconies along the facade and the waterfront were replaced with our BalcaSmart® Aluminium and TerraSmart® Aluminium systems, which are ideal for remediation, new-build, and refurbishment projects.The refurbishment project was completed this year, delivering peace of mind to residents and owners alike, especially after the Grenfell Tower fire and changes to fire safety regulations.Installed with great care and attention to detail, seamlessly meeting stairwells and other structural elements, our BalcaSmart and TerraSmart Aluminium systems complement the overall aesthetics of the building, are lightweight, long-lasting, and most importantly able to meet the load requirements of its walkways, which also form part of the fire escape routes.Both BalcaSmart and TerraSmart Aluminium systems carry our IGNO mark of assurance for non-combustibility and reassure specifiers by way of a 30-year warranty and a 60-year design life (when used as part of a complete RYNO IGNO system).

Following the devastating effects of the Grenfell Tower tragedy, Hatfield Close & Gerrard House fell into the category of social housing buildings that needed to be reclad to meet safety standards and Terracotta cladding offered a solution that satisfied the required standards and ticked all the boxes. BackgroundOn the 14 June 2017, a disaster that shook the nation taking away the lives of 72 people, injuring many others and devastating families and a whole community became the core of public unrest and resulted in a mass scale enquiry that identified around 2,000 buildings over 18m tall clad in dangerous combustible materials in England alone. The cladding crisis exposed that not only did the buildings pose an immediate fire risk to residents but also saw flat owners facing building insurance premiums, extensive and costly remedial work and mortgage lenders deeming the properties unsafe and ceasing to lend money against them. The Grenfell tower tragedy resulted in the review of the building regulations nationally and internationally in countries including Australia, Malta and The United Arab Emirates and in a government pledge of over £5bn towards the remediation of fire safety problems in high rise buildings. The three Hatfield Close & Gerrard House blocks were identified as being clad with ACM, the cladding material used at Grenfell. The projectAlthough originally constructed as a concrete frame with brick infill sections, the Hatfield Close & Gerrard House buildings experienced weather penetration issues during the 1980s and the 1990s that led to a programme of improvements which included the introduction of an ACM rainscreen system in the 2000s which during the post Grenfell tall buildings cladding mass review was found unsafe. Only weeks later emergency works to strip the hazardous cladding began.  Although the primary objective of the project was to improve the fire safety performance of the three blocks, the project team took the opportunity to redevelop the buildings to also improve their aesthetic and structural and thermal properties. The nature of the project called for a holistic approach led by a multidisciplinary team which included Michael Dyson Associates Ltd, a housing consultancy firm that specialises in the social housing sector, social housing main contractor United Living, a Lewisham Homes & Fire risk manager, independent consultants and resident representatives. The team, with guidance from the planners selected terracotta cladding as the material of choice due to its non-combustible A1 fire rating and robustness. In addition to its essential non-combustible fire classification, terracotta offered a large range of tile colours, shapes, profiles and textures that gave the team design freedom and opened the possibility to improve the aesthetic appearance of the blocks at the same time as offering durability due to being a natural product with no synthetic dyes and a life expectancy of 60 years +. The terracotta cladding system offered the façade contractor Novo Facades a simple method that allowed them to deliver a clean and non intrusive installation process which was key as the residents were living in the buildings all along. The project became a construction referent of inclusion and savoir faire. It was a winner in the Inside Housing 2020 Resident Safety Campaign Awards, it was shortlisted for ‘Best Community Engagement’ and Won ‘Project of the Year £10 million to £25 million’ awards at the 2021 National Building & Construction Awards. SolutionTerracotta facade panels are one of the cladding resources of choice in the market because it is a natural and versatile material that gives architects freedom of expression whilst it gives cladding and envelope contractors the advantages of a quick and easy installation process. The Argeton system is one of the principal terracotta systems used worldwide not only because it is a natural and versatile material but also because it offers a technical and cost-effective solution for the residential, commercial and health and education sectors. Argeton is CE and UKCA marked and one of the most tested systems in the market including a BBA and an EPD. NHBC approved and not subject to any restrictions on building height or proximity to boundaries thanks to its Euro-class A1 Fire certification, it is no surprise Argeton is one of the materials of choice not only in new builds but also for refurbishment or re-clad. Durable and fully recyclable, ISO 14025 and EN 15804 (European BREEAM equivalent) certified, sustainability is at the heart of Argeton’s values. Argeton terracotta cladding systems are available in a range off the shelf and bespoke profiles, in lengths to suit and in natural, glazes, digital print and engobed finishes. https://tellingrainscreens.co.uk/profile-and-finishes/

Twice the height of any other building in Cyprus, the ONE Tower commands the skyline of Limassol. Sitting on the palm tree lined seafront close to both the city’s bustling business district and its quaint old town, the new development offers 83 luxurious residences, leisure and commercial opportunities set across 37 floors. Its award-winning curved design reminiscent of a yacht’s sail, stands at 170 m high which, coupled with its coastal location, presented a unique set of passive fire requirements for its facade. Key informationCompletion dateSummer 2020SectorResidential | Retail | LeisureEnd clientPafilia Property Developers Ltd.Main contractorArabian Construction Company (ACC) | JV Partners | Joannou & Paraskevaides Group (J&P Group)Facade contractorGlassline Industries LtdArchitectWKK ArchitectsDistribution PartnerDPS TechnoIndustrial Ltd Products usedSiderise RH Horizontal Cavity Barriers for Ventilated CladdingSiderise RVG Vertical Cavity Barrier (galvanised mild steel brackets)Siderise OSCI Open State Cassette Insert DesignThe sheer height of the tower meant it was vital to ensure the facade construction contained adequate passive fire protection, complying with local regulations and ensuring ongoing safety throughout the building’s lifetime. After working with our products and our Cypriot distribution partner DPS for a number of years, facade contractors Glassline specified a combination of open state Siderise cavity barriers and cassette inserts. The RV vertical and RH horizontal cavity barriers are designed to allow the facade system to maintain airflow and drain away any moisture within its construction but, in the event of a fire, rapidly close the ventilation gap to create an effective hot smoke and fire seal. Both products achieve Class A1 to EN 13501-1 and provide 120 minutes fire integrity. The barriers are complemented with the use of OSCI Cassette Inserts which are Class A2 rated. All these products have undergone rigorous third party testing to ensure dependable performance. These include single product tests and testing as part of a large-scale system, such as BS 8414 (1&2) and NFPA 285, demonstrating their performance within a complex, high-rise cladding system such as that used on the ONE Tower. For more detail about the standards the products meet, please visit the individual technical data pages. In addition to providing straightforward passive fire protection, the stonewall lamella core of the RVG vertical cavity barriers allows them to accommodate the natural movement associated with rainscreen facades. This is especially important on this exposed seafront project. It is also for this reason that the cavity barrier brackets were specified in robust galvanised steel, protecting them from corrosion caused by the sea air.InstallationAll Siderise products are designed to be easily installed— a key benefit on this large-scale project, enabling it to be finished to a high standard without compromising the project timeline. The RV vertical barriers and then the RH horizontal barriers were cut to the correct size and installed by Glassline using Siderise galvanised steel brackets and foil tape. Where the two products met, they were simply tightly abutted, and the joints sealed with foil tape to ensure continuity of intumescence and therefore fire protection. The OSCI cassette inserts were then fitted as part of the cladding system, installed directly behind the cassette panels and in parallel and centrally aligned to the RVG and RH cavity barriers. This helped to simplify detailing and ensure the ventilation gap met the project requirements. Technical support and site services were provided by our partner DPS throughout the design and installation process, in-keeping with the Siderise ethos of standing by the side of our customers to deliver optimum results.Final CommentsCreated in collaboration with a number of renowned international and local firms and suppliers, ONE Limassol Tower not only stands as a symbol of the city’s exciting future, but also of what can be achieved when diverse skills, expertise and vision are brought together. The selection of tested Siderise products chosen for the project will help to ensure that the building remains a safe and beautiful home and landmark for the people of Limassol for many years to come.Image copyright (C) Pafilia www.pafilia.com

Close to the historic market town of Nantwich, renowned for its medieval timbered architecture, Chamberlain Developments in association with DEP Architects have created nine bespoke two, three and four-bedroom homes in the wonderful bucolic village setting of Acton. Eighty intricate Keystone brick slip feature lintels feature across the ground and first floor door and window openings on the phase two development.ChallengeThe new homes are sympathetically placed around the restored and converted traditional 18th century farmhouse, ancillary barns and outbuildings from the initial phase one development, situated near the 13th century St. Mary’s Church. The architecture plans specified a combination of bespoke brick slip flat gauge arches, parabolic arches and bullseye lintels, each requiring a flawless brick surround finish in keeping with the heritage sensitivity of the site.The plans received from T G Builders Merchant originally included brick slip lintels for the front and rear elevations only, however, Keystone’s team were able to offer Chamberlain Developments a solution for the other more intricate brick details and the specification was therefore increased to include additional brick slip flat gauge arches and bullseye lintels for the side elevations.SolutionKeystones dedicated technical team ensured each bespoke lintel was manufactured to size, shape and aesthetic requirements within the project build schedule. A consignment of bricks were collected from site, cut and bonded offsite onto load bearing lintels using a BBA approved construction adhesive. The weatherproof controlled environment helped to guarantee a high quality brick finish and eliminated delays onsite from disruptive weather conditions.The flat gauge arches were designed with a 70-degree brick skew and all lintels were suited to a wall construction of 325mm, 215mm brick height and 102.5mm soffit return, removing the need for skilled labour onsite. The prefabricated brick slip lintels were delivered to site ready for final pointing, with larger and heavier lintels including lifting hooks for an easier and safer installation.Testimonial“We have specified Keystone many times before and have always been impressed with both the company’s products and customer support. At our Church Farm development, the brick slip feature lintels played a key part in the design of the new build homes. They look fantastic and the excellent detailing ensures they blend seamlessly with the rest of the brickwork.”Richard BullockContracts Manager at Chamberlain Developments
