Technical Editor, Bruce Meechan hears from Ged Ferris of Cembrit about the wide selection of board products the manufacturer can offer for internal and external construction applications.

The term one-stop-shop may be over used in the UK building products supply chain, but the range of boards offered by long-established manufacturer, Cembrit can provide specifiers with solutions to every sort of challenge from interior refurbishment and the creation of wet rooms within social housing units, to some of the most daunting logistical demands faced by burgeoning offsite or MMC sector.

The majority of the board options offer not just excellent physical characteristics, but a strong lineage and a long track record of service, both here and on the Continent.
As UK Marketing Manager, Ged Ferris, commented during our interview: “We have the product range to facilitate the needs of everyone from offsite system fabricators to refurbishment specialists and the growing self-build market.

Not just a Five-star range, but a range with five main stars and many product variations: Cembrit’s flat boards encompass all the key performance parameters including moisture resistance, fire resistance and structural strength, as well as providing a versatile substrate for commonly used finishes.

THE RANGE General purpose and specialist requirements solved by Cembrit’s boards

The product within the range which has shown the most rapid growth across the market is PB: a versatile tile backer or render backer board, mainly being used for the refurbishment of bathrooms, it is popular due to its low weight and ease of cutting which facilitates installation, and the robust long term performance. Cembrit has developed a version called Flex which can be fixed down to radii of just 150 mm. Both conventional PB and Flex features polystyrene spherules and an edge reinforcement detail that uses a special fabric allowing butt jointing and fixings close to edges for maximum rigidity. Flex installations might then form a column casing that would be rendered over or covered with a small format mosaic.

Where social housing providers are seeking to fit out full wet rooms for those who might need assistance with personal care, then there is also a Special Performance board which was originally developed for use in places like swimming pools.

The biggest seller still, though in terms of volume is Cempanel which is primarily specified for dry-lining and sheathing: the internal skin to a rainscreen cladding build up. Depending on dimensions, Cempanel can also take racking loads: being produced in thicknesses of 8, 10, 12 and 16 mm. It is also often used as a render carrier in exterior applications.

The FR board can provide up to 120 minutes of fire resistance and is widely specified for soffits in corridors, lift lobbies and other communal areas to buildings where the consideration of escape routes and combating the surface spread of flame are essential.

Ged Ferris added: “We see our board range as being of particular value to manufacturers of modules, pods, timber frame panel systems and other prefabricated solutions. They could even form the face to SIPs (Structural Insulated Panel) systems.

“As well as the merchant stockist, clients can also purchase through ‘optimizers’ – board cutting specialists who supply the exact sizes they need to make our standard product coordinate with elevation widths, window openings and things like flues or other service penetrations. It will also be a real advantage to customers that such a comprehensive selection is available from a single source.”

Responding to market demand, Cembrit is also making its cladding boards available as BIM objects in partnership with its Scandinavian parent company. These can be viewed via the company’s website at www.cembrit.co.uk or by contacting the company’s technical advisory service via email.

Fibre cement Cedral Click has helped a self builder in Northamptonshire achieve an architectural fusion between their property’s impressive angular design and the neighbouring Grade II listed church spire.

The facade’s ability to visually reduce the impact of the building on the landscape is based around a symbiotic relationship with the slate grey Cedral Click and honey coloured stone, which work together to make the most of sunlight, shadow and sightlines in this beautiful Conservation Area of Broughton, Northamptonshire.

This juxtaposition of facade materials was accentuated by the architects following through the angular roof design within the facade. The effect is to further reduce the building’s dominance, whichever elevation it is viewed from, creating a structure that appears less imposing, yet retains a geometry that works with the church spire in the background.

Aside from Cedral Click’s visual possibilities, the flush-fitting boards give a sense of elegance and weightlessness, avoiding the issue on some buildings where a solid facade over dominates the overall design.

Cedral Click, with its lightweight yet strong properties, enabled the designers to create a structure with complex, engaging forms, yet one that still appears deceptively at home in this Conservation Area.

The 300m², three bedroom home was the inspiration of the Manning family and Market Harborough-based Leaf Architecture. Mr Manning said: “The support from Marley Eternit has been phenomenal, our sales contact took the time to meet us and discuss exactly what it was that we wanted. We couldn’t fault their customer service and Cedral Click has far exceeded our expectations and created a striking feature.”

Cedral Click is the UK’s first and only fibre cement tongue and groove cladding system where the planks fit together flush and is offered in a range of seven colours.

With the visual appeal of natural timber and the durability of a fibre cement product, Cedral Click has good resistance to fire (A2-s1,d0 to EN13501-1). Being made from fibre cement means that it won’t warp or shrink over time like timber. The installers used a concealed fixing system to enhance the sheer, smooth facade.

Cedral Click achieves an A+ rating in the BRE (Building Research Establishment) Green Guide to Specification based on generic rating: Cedral Click – autoclaved fibre cement (calcium silicate) cladding – (Element Ref: 806220701, 806220675, 806220676).

Marley Eternit also offers Cedral Lap weatherboard, a more traditional, clapper-board aesthetic where the planks overlap. Both Cedral Click and Cedral Lap are made from fibre cement, which ensures low maintenance and a life expectancy of 50 years.
