"intumescent"

With fire doors under close scrutiny in the aftermath of Grenfell, the public’s trust in their ability to protect lives and assets urgently needs to be restored. Rebuilding confidence in fire rated doorsets needs a focus on every element of its construction, with one of the most critical elements being the intumescent seal. Intumescent seals have now been used in fire rated doorsets for four decades. They help to stop the spread of fire and smoke, with the most common types in the UK being manufactured from compounds of sodium silicate or intercalated graphite.

Raiz cocktail bar is a trendy nightspot in the centre of Ponta Delgada, the bustling capital of the Azores. A busy venue, popular with locals and tourists alike, Raiz bar is a modern, industrial design, featuring exposed steel beams and glass walls with steel staircases connecting two floors. It was important to the owner, Gabriel, that as a main feature of the building design, the steelwork was not only protected against corrosion and fire, but also looked good, to enhance the ambience of the bar.One night, soon after closing, a fire took hold. The fire raged through Raiz bar destroying many fixtures and fittings and causing a substantial amount of damage. Initially it was thought the cause was from an electrical short-circuit, but having been ruled out it is now being investigated as a deliberate, criminal act. The fire burned for three hours before being brought under control and finally extinguished by the fire crews. Being outside of opening hours, the building was empty and fortunately no one was hurt.As the damage was assessed, it became apparent that the steel structure remained intact. Gabriel’s choice of Hempel’s intumescent coatings not only protected the steel against the heat and flames, but allowed additional time for the Fire Department to bring the fire under control.

The Hackitt Review has brought to the broader public attention the myriad of standards and testing or assessment methods that specifiers and the fire protection sector has had to carefully navigate for many years. And whilst the debate continues about the best way forward in respect of specific applications, one positive step that fire door manufacturers can take right now is to go back to basics and check whether their supply chain for fire resisting components is opening the door to risk.Fire resistant products like fire rated glass, intumescents and core materials are composed to precise specifications.

Fireshield® vapour permeable membrane, which is designed specifically to improve the fire protection behind cladding has been chosen for a new Science Centre at Bevington Primary school in the Royal Borough of Kensington and Chelsea, London.The project includes a brand new Science Studio, plus before and after school club buildings.SIP Build UK was appointed as frame subcontractor for the project and chose the Fireshield membrane as part of the SIPS panelling system. Chris Duckworth from SIP Build UK explains: “We chose Fireshield as it provided the project with a number of really important benefits. Fireshield is a high-performance breather membrane which enables us to achieve the requirements in terms of fire protection without compromising on vapour control.Fireshield was also ideal because it is easy to use and allowed us to achieve the requirements in one process, using just the membrane, rather than the typical approach of two, cement board and a membrane.”Fireshield is the culmination of leading research to produce a vapour permeable membrane with a intumescent coated surface, which has a unique composition that actively reacts to help protect the materials underneath. The intumescent coating helps protect the substrate by reducing the risk of fire taking hold and significantly reduces the formation of droplets and smoke.The BBA Certificate awarded to Fireshield confirms that it has enhanced performance in relation to reaction to fire classification, will reduce the risk of interstitial condensation, and will have a life equal to that of the building in which it is installed.Fireshield complies with BS5250, BS4016 and NHBC requirements for vapour permeable walling underlays. It is installed and fixed to the substrate in the same manner as standard breather membranes using mechanical fixings. Applications include both commercial and residential buildings including apartments and student accommodation, as well as Rainscreen cladding and applications over 18m high (11m in Scotland).

Park of Poland is one of Europe’s premier holiday centres. Located in Wręcza, around 60 kilometres from Warsaw, the park offers a range of attractions, including an indoor water park, theme parks and other facilities such as hotels, bungalows, office spaces and apartment buildings. Park of Poland was completed at the end of 2019 and is expected to attract millions of visitors each year.Our coatings protect all 4,500 tons of structural steel at Park of Poland and include a high-quality passive fire protection system based on our intumescent coating Hempacore One FD to improve safety for visitors and staff. Applied to the structural steel, Hempacore One FD will expand if exposed to high heat, insulating the steel beneath. In a fire, this will extend the steel’s load-bearing capacity for up to three hours.

Due to proven technology and a proven track record, AkzoNobel was chosen to supply fire and corrosion protection coatings for the Akpo FPSO.The vessel is 310 meters in length with facilities for 240 crew members and storage for two million barrels of oil. With two processing trains for the separation of oil and water, and an average production capacity of 225,000 barrels of oil equivalent per day, the Akpo FPSO is a high-value installation. The risk of catastrophic hydrocarbon fires was a significant concern during construction, as was the risk of metal corrosion in the harsh offshore conditions.With outstanding technical knowledge and a long, successful track record in the new-build FPSO market, AkzoNobel was selected as the protective coatings supplier for the project. Chosen from the market-leading Chartek range of fire protection products, Chartek 7 is a light-weight epoxy intumescent ideal for providing PFP (Passive Fire Protection) in offshore installations, due to its excellent water and chemical resistance.

Essential Protection for Tall Buildings.As one of the world's leading coatings companies, we strive to be at the forefront of design trends and our International range of protective coatings and passive fire protection products is developed to complement architectural innovations.With its curved façade and spiralling form symbolizing China’s emergence as a global financial power, the Shanghai Tower is world's second tallest building (behind Burj Khalifa in Dubai), after its six-year construction was completed at the end of 2015.Shanghai Tower is one of the most advanced sustainable tall buildings in the world and goes to great lengths to generate its own energy.Around 200,000 liters of our protective coatings and intumescent fire protection products, including Interchar 1983, were used to provide fire protection for stair steel structures and the façade’s supporting steel structures for up to 90 minutes.We were the company of choice for the owner, painting applicators and the fabricator.

Chartek 7 was specified for this project, as an epoxy intumescent coating with an outstanding track record of protection against hydrocarbon fires dating back to 1995. The PFP system had to be able withstand explosion loads in excess for 4bar while maintaining its integrity, and Chartek 7 easily met these requirements. Using Chartek also provided productivity benefits, due to its high build and simple meshing system, along with a low weight per unit area, helping to reduce transportation costs for pre-fabricated units.Pre-fabrication played an important role in this project, due to the harsh environmental conditions and remoteness of the site. Steel components were constructed at locations across Europe, with the emphasis on minimizing installation and delivery costs. The ability of AkzoNobel to provide standardized global products and a high level of technical support helped to streamline and add value to this process, complementing the productivity benefits of Chartek.

THE PROJECTThe Waterside Park project features multiple banks of a fire rated mailboxes that comply with the BS 476 Part 22 offering a one hour integrity rating that will ‘contain and form a break to a fire’.The bank of mailboxes are recessed into a wall and integrated with a finishing surround frame providing a high quality edging to the products, hiding any gaps between brick and mailbox and ensuring a high quality finish.The mailboxes feature an inward sprung flap, which is a standard feature across the fire rated mailbox range. An intumescent strip is placed on the internal side of the mail flap, which expands when the temperature increases and ensures that the flap is kept closed – stopping the oxygen flow into the mailbox and reducing the risk of fire spreading through the mailbox.Each mailbox used in this project has been fitted with a unique identification numbering vinyl with a black colouring to easily show the users (both residents and postal operatives) where each mailbox is situated.

This scheme was designed by the architects Hawkins Brown and constructed by Mace, who were very easy to work with and have a great project team.One of the main challenges of the project was the fact that is was being constructed during lockdown, and both design team and project team were all working from home, but because of such good communications across the teams, everything flowed very well. N06 East Village is located at the site of the former 2012 Athletes Village and close to the London Olympic Park 2012, so there’s plenty of sports locations nearby!The façade sections were constructed using a modern method that involves some manufacturing and assembly being completed offsite. They were pre-assembled and fixed offsite onto the precast concrete floor units and this new high rise construction solution, removes the need for scaffolding Because each floor is fully enclosed, it reduces project time and the risk of site operatives working at height and increases project speed time with less labour needed on site. This was especially beneficial considering construction was during the Covid-19 pandemic. It is believed that throughout this project there was 40% less vehicle movements to and from site and 70% less site waste created.*We supplied the original Quadra metal riser doors throughout the two residential towers however we have since improved the doorsets and they are now Quadra+. N06 East Village project has a modern interior with bright, bold colours featured on both the inside and the outside façade. Selo’s concealed riser doors were a perfect fit with their interior design providing a sleek, flush solution throughout the corridors.This project was one of the first major projects that we supplied our Quench fire-stopping protection to after they requested a factory fitted fire stopping solution. Quench is a safe and reliable solution that is pre-fitted to the riser door frame, removing the need to apply intumescent mastic. It has a 120minute fire resistance rating when used in conjunction with Selo’s Quadra+ riser door system. This solution removes the need to work inside the riser to apply the intumescent and thus removing the fall risk and hazardous working environments.*Source: https://www.cast-consultancy.com/knowledge-hub/plot-n06-east-village/

Promat has played an instrumental part in the fire protection of the latest unit of GLP’s warehouse and logistics facility, G-Park, Northampton - providing a tailored 240-minutes fire resistance solution for Unit 4, a132,000 sq. ft speculative warehouse/distribution unit.  Situated within the popular Moulton Park industrial estate just north of the town and within 10 miles of J15 of the M1, G-Park has exceptional transport links, access to national markets, a locally skilled workforce and is home to a wide range of regional and national companies.   At short notice, the latest and final unit within the park required a solution that provided 4-hour fire resistance for the steel frame construction. Sub-contractor FAA Installation Ltd traditionally uses intumescent paints in its projects, but as this method was unable to meet the 4-hour fire protection required for the steelwork structure it was decided that boarding would be a more suitable alternative.  Promat VERMICULUX®-S and TD Boards® were specified for the project by Encon, a leading Promat distributor, as they knew that these were two of a limited number of products on the market that could meet the project’s requirements.   Promat worked closely with Encon and FAA on the final specification to provide a solution that could not only achieve the 240-minute requirement, but could also overcome the design complexities of the project, including fixing to both the structural steel and cladding rails, which most traditional boards were unable to accommodate. The completed installation demonstrates how VERMICULUX®-S and TD Boards® can interface together to create robust fire protection for warehouse and industrial applications. 

The FM company of a large Yorkshire Hospital engaged with wall & door protection specialists, Yeoman Shield, to resolve the unsightly and problematic damage that was occurring to fire doors in a busy specialist unit.Such damage, caused by the everyday passage of people, trolleys and equipment, if not attended to, may have become detrimental to the functioning of the fire doors.Yeoman Shield were able to provide a comprehensive fire rated door protection system, which when installed does not affect the fire integrity, to help combat and break the damage cycle, helping to prolong the life of the doors.Door Edge protectors, either FD60 or FD30, according to a doors rating, were installed to the vulnerable leading and hinged edges of the door to prevent chipping and splintering and helping to maintain the recommended 3mm gap between doors and frames.The leaves of the doors were covered with Yeoman Shield’s 2mm thick FalmouthEx protection panels at either full or half height dependent on where the impact was more prevalent, preventing dents or holes from manifesting in the future.Standard glazing beads were replaced with PVCu clad units, complete with corresponding intumescent strip, helping to protect an element of the door much prone to damage.A further part of the fire door refurbishment project was the addition of an Architrave and Stop Lath protection system. These systems come complete with hardwood (stop lath) or MDF core (architrave) with a PVCu cover and as such not only becomes resilient to impact damage but eliminates the requirement for redecoration and repair.Yeoman Shield were able to provide fire certificates for all parts of their fire door protection system offering compliance assurance to the client.For more information on Yeoman Shield cost effective wall & door protection systems go to www.yeomanshield.com or call 0113 279 5854.
